“I was struck by how clean,<br />

natural and quiet the receiver sounded in<br />

comparison to some DSP based radios. I found<br />

the Omni-VII a real pleasure to listen to –<br />

in any mode.” – W1ZR, in the ARRL<br />

Product Review, QST July 2007 “What a neat little package!<br />

I’m having more fun with this<br />

thing!” – K1SA<br />

“High quality<br />

manufacturing…overall<br />

a very impressive<br />

transceiver” – W9AC<br />

“As an avid CW operator, it is<br />

like listening to your favorite music<br />

while operating.” – N1SW<br />

“I can say that in my 30+ years of<br />

operating I’ve never enjoyed a rig more than the<br />

Omni-VII. The audio is superb as is the QSK, ergonomics,<br />

receiver characteristics and<br />

on and on.” – W7TEA<br />

“Close-in dynamic range<br />

unsurpassed by any other general coverage<br />

radio.” – Radio Society of Great Britain<br />

– K6LE<br />

“Once again, Ten-Tec has<br />

produced a superb transceiver,<br />

with great SSB audio and their<br />

famous QSK.” – K4SQR<br />

“My Dad, KB2LAU, in Florida has<br />

become active again using my Omni-VII in<br />

Vermont. He is enjoying daily contacts [via<br />

Internet remote control]. Being a ham with<br />

limited to no antenna options, this has been<br />

a great opportunity.” – W1ZN

Our “Better Halves”<br />

This summer, I had the pleasure of<br />

attending the WØDXCC convention in<br />

Rochester, Minnesota. It was a fun day<br />

with both a DX track and a contesting<br />

track. I had a chance to chat with K9LA,<br />

K7BV, KX9X, N6BV and many others.<br />

The day was capped off by an evening<br />

banquet attended by more than 150. At<br />

the banquet, I was humbled and honored<br />

to receive the WØ Contester of the Year<br />

award. I harbor no belief that this means<br />

I’m the most accomplished contester in<br />

WØ-Land. Perhaps, however, it was more a<br />

recognition of how much I love contesting<br />

and enjoy promoting it any way I can.<br />

When I returned to the table after receiving<br />

the award, my wife Marianne looked<br />

at the plaque and said, “Congratulations<br />

but, you know, I think there should be<br />

an award for contesters’ spouses.” As I<br />

thought about it, I realized that Marianne<br />

was right on the money. Speaking for<br />

myself, I wouldn’t be able to be anywhere<br />

near as active in radiosport if it were not<br />

for my wife.<br />

In the fall and winter, she gives up a<br />

fairly sizeable number of weekends to<br />

allow me to participate in contests. For<br />

those contests where I have not abandoned<br />

her to do a multi somewhere, she<br />

asks me what times I want my meals and<br />

what I want for snacks during the contest.<br />

When I used to run the amplifi er a lot, it<br />

meant that the TV and telephones were<br />

all but unusable during the weekend. More<br />

recently better technology and fi lters have<br />

helped to resolve this problem. When I put<br />

up my tower and beam last year and was<br />

scouring the Internet for used towers and<br />

antennas, she said to me “Look, why don’t<br />

you just spend some money, buy new and<br />

do it right?”<br />

Perhaps an example that best typifi es<br />

this support is one that those in the Minnesota<br />

Wireless Association still kid me<br />

about. One of the statements on my plaque<br />

says, “Silver Fist and Silver Zipper.” Here’s<br />

the back story.<br />

When Marianne and I married in 1991<br />

and I started operating the ARRL November<br />

Sweepstakes from our new home, she<br />

noticed that I wore the same sweat suit every<br />

time I operated CW SS. It’s extremely<br />

comfortable, and I sort of consider it my<br />

“lucky SS sweat suit.”<br />

After one Sweepstakes a number of<br />

years ago, I mentioned to Marianne that<br />

I might have to retire my favorite contesting<br />

sweat suit because the zipper was<br />

broken. Nothing more was said, but the<br />

following November, as I came out of my<br />

pre-SS shower, lying on the bed was my<br />

favorite contesting sweat suit — cleaned,<br />

pressed and with a brand new silver zipper<br />

installed!<br />

I know I’m not alone in appreciating the<br />

contribution that our better halves make to<br />

our hobby. We discussed this a while back<br />

on our local refl ector, and there were some<br />

other interesting testimonies to true love.<br />

Several wives of MWAers volunteer to<br />

drive their husbands around the entire<br />

state of Minnesota all day on a cold Saturday<br />

in February to allow them to play<br />

rover in the Minnesota QSO Party. WØAIH<br />

tells how his wife Mary accompanies him<br />

on tower projects and spends the day operating<br />

the electric winch sending Paul up<br />

and down the tower. She refers to herself<br />

as his “winch wench,” and Paul could not<br />

do what he does without her help. I know<br />

that there are many others out there who<br />

are able to enjoy contesting even more<br />

because of the support we receive from<br />

our spouses.<br />

Some spouses have gone on to become<br />

hams themselves, but even if they haven’t,<br />

I hope we will all continue to realize how<br />

important they are to the success and<br />

enjoyment of our radiosport passion.<br />

If you have similar stories of support, I<br />

would be interested in hearing them.<br />

New Louisiana Contest Club<br />

In the past I have mentioned my belief<br />

that contest clubs are crucial to the continued<br />

growth and enjoyment of contesting.<br />

Earlier this year K4RO addressed the<br />

benefi ts of contest clubs in his “Contesting<br />

101” column. It was great to hear how a<br />

group of contesters in Louisiana last spring<br />

decided it was time to form a contest club.<br />

I contacted Scott, W5WZ, with my congratulations<br />

and asked if he might write an<br />

article on the process they went through to<br />

form the Louisiana Contest Club. His story<br />

appears elsewhere in this issue. For me,<br />

Alan Dewey, KØAD<br />

kØad@arrl.net<br />

it was fun and informative to hear about<br />

the process they went through to birth the<br />

LCC. I hope their story will be an incentive<br />

to other “pockets of contesters” out there<br />

who have been thinking about forming a<br />

contest club.<br />

Mini WRTCs<br />

WRTC <strong>2010</strong> is less than two years off.<br />

As the event approaches and the teams<br />

are selected, contesters will continue to<br />

debate the fairness of the selection process.<br />

Nonetheless, the teams selected<br />

by and large will represent an extremely<br />

accomplished level of achievement in contesting.<br />

But what about the rest of us?<br />

One solution might be to compete in a<br />

“mini WRTC.” Although it may not compare<br />

realistically with the level of planning and<br />

logistics that characterize a real WRTC<br />

operation, it still can be a fun event for local<br />

contest groups to fi eld some two-person<br />

teams during the IARU World HF Championship<br />

event in July. One such mini WRTC<br />

took place on the West Coast this summer<br />

and is described elsewhere in this issue.<br />

Maybe this is something your local contest<br />

club may want to try next summer.<br />

Getting It Right<br />

Readers pointed out an inadvertent<br />

omission in the <strong>Sep</strong>tember/October issue<br />

of NCJ. In Table 1 of “A Simple 2-Element<br />

Vertical Array for 160 Meters,” by John<br />

Barcroft, K6AM, the front-to-back ratio<br />

for the fi rst quarter-wave entry should be<br />

40 dB.<br />

In addition, a schematic diagram in the<br />

same article contained some incorrect<br />

data. In Figure 3, the impedances at the<br />

input of the reversing relay should be Z =<br />

31 + j94 and 171 + j37. John thanks CN2R<br />

for catching the error.<br />

Contest University 2008 at<br />

Dayton Adds Graduate Courses<br />

Building on its fi rst-year success, Contest<br />

University (CTU), www.contestuniversity.com,<br />

returned to Dayton this year<br />

with a curriculum that included courses<br />

for new and returning students. I had the<br />

pleasure of attending CTU this year for the<br />

fi rst time and, like many, I was impressed<br />

with the organization and professionalism<br />

with which it was executed. With more than<br />

200 attendees, the fi rst-year courses and<br />

graduate courses were located in adjacent<br />

rooms at the Crowne Plaza Hotel in<br />

Dayton on the Thursday prior to Dayton<br />

Hamvention®. See Figure 1 for the class<br />

rundown.<br />

Through careful scheduling, it was<br />

possible to organize the program so that<br />

some courses could be presented to both<br />

fi rst timers and grad students with the<br />

room divider removed, while other classes<br />

were taught separately to fi rst-year and to<br />

graduate enrollees.<br />

The day began with a great talk by<br />

Randy, K5ZD, to the entire group on<br />

contesting ethics. This was an extremely<br />

strong start to the day. Feedback from CTU<br />

attendees affi rmed that this was one of<br />

the most important and well-received of<br />

the day’s presentations. I think Randy really<br />

drove the point home when he asked<br />

simply, “What do you do when no one is<br />

looking?”<br />

First and second-year students then<br />

broke into separate groups for classes<br />

addressing station design, antennas and<br />

propagation, QSO party and mobile contesting<br />

and RTTY contesting. After lunch<br />

Doug, K1DG, gave a brief talk to the entire<br />

group on an extreme shack makeover,<br />

followed by the eyeball sprint. The eyeball<br />

sprint was a great way to get students out<br />

of their chairs and moving before any postlunch<br />

sleepiness set in.<br />

Following separate sessions on station<br />

design, advanced RTTY contesting,<br />

basic and advanced VHF contesting, and<br />

DXpeditions, the fi rst year and graduate<br />

students joined up again for the fi nal class<br />

of the day. This was a very interesting and<br />

useful presentation on contest radio performance<br />

by Rob Sherwood, NCØB.<br />

All CTU attendees received a very welldone<br />

printed and spiral-bound notebook of<br />

the day’s presentations. This was not only<br />

a great aid for taking notes but a handy<br />

reference after CTU was over. I’ve already<br />

referred to it a number of times. CTU also<br />

posted revised slides to all attendees<br />

after the event concluded, to make sure<br />

students had the latest information about<br />

the topics covered.<br />

4 November/December 2008 NCJ<br />

Figure 1 — The class agenda for Contest University 2008 at Dayton.<br />

As a first-year attendee of Contest<br />

University, I felt the instructors put a tremendous<br />

amount of time into preparation.<br />

All the presentations were fi rst-rate. Like<br />

many things in our hobby, this was a labor<br />

of love as they gave back to the contesting<br />

community. I encourage all to give a<br />

big “thank you!” to K3LR, K5ZD, K1DG,<br />

W3LPL, NØAX, K8MR, WØYK, W3ZZ<br />

and NCØB the next time you talk to them.<br />

Better yet, come to CTU 2009, and do it<br />

in person!<br />

Finally, it is important to recognize some<br />

of the sponsors that helped make Contest<br />

University 2008 such a success. These<br />

included Icom America, DX Engineering,<br />

SuperBertha, CQ Magazine, Comtek Systems<br />

and QTH.COM — KA9FOX.<br />

Comments from Attendees<br />

Using a list from K3LR, I sent a request<br />

to most CTU 2008 graduate students<br />

soliciting comments on their experiences.<br />

Here’s a representative sampling.<br />

♦ The programs in year one and two<br />

were both fun and informative. There was<br />

something for contesters at every level<br />

and interest. It doesn’t get any better than<br />

to have the opportunity to listen and talk<br />

with expert presenters who really know the<br />

sport. During session breaks you get to<br />

meet a large room full of other contesters.<br />

How great is that? It’s a blast and an allaround<br />

super program. — Ralph, K1ZZI<br />

♦ I enjoyed the grad level as much<br />

as I did the introductory level. I’m a little<br />

pistol, but I can apply a lot of what was<br />

presented even on a modest scale. —<br />

Randy, K9OR<br />

♦ It was good to get a lot of contesters<br />

Al Dewey, KØAD<br />

together in one room [to interact], as you<br />

hardly meet some of them face to face.<br />

The sprint idea tried to help with that, but<br />

I am not sure it succeeded as it brought<br />

out the naturally competitive nature of the<br />

contester. I think the talks were good, and<br />

of course, there wasn’t enough time for<br />

everything. Organization was great; Tim<br />

kept things rolling. — Ed, K1EP<br />

♦ I attended the graduate school this<br />

year. The most useful part was the discussion<br />

on contest station design [and]<br />

how to be effi cient in that aspect. [CTU]<br />

was more effi ciently run this year than in<br />

the fi rst year. I think in future years more<br />

and longer classes on one topic such as<br />

contest station design would be useful.<br />

Giving less than an hour for a topic is nice<br />

for an intro, but then you really need the<br />

intensive class to carry through. — Steve,<br />

K7AWB<br />

♦ This second year I got to talk with<br />

others who had put into practice some<br />

of the items gained in the fi rst session. I<br />

too had changed some things around in<br />

my station and started trying new things<br />

I picked up the fi rst time around. With the<br />

sunspot cycle on the way up, just talking<br />

with and hearing the best in the business<br />

talk about their experiences was worth the<br />

day spent. — Jerry, K1SO<br />

♦ My comments must start [by commending]<br />

Tim’s precise planning and<br />

attention to detail. Everything is done to<br />

make this an exceptional learning experience.<br />

I have been an amateur for nearly<br />

50 years and always learn tons of stuff.<br />

Ward, NØAX, is entertaining and informative<br />

2009 Plans from K3LR<br />

CTU Chairman Tim Duffy, K3LR, has offered<br />

some thoughts of his own regarding<br />

CTU 2008 and what is planned for 2009.<br />

He expects CTU 2009 registration to open<br />

in December. “Based upon two outstanding<br />

years of Contest University at Dayton,<br />

plans are under way to make CTU 2009<br />

the best ever,” he promises. “The schedule<br />

will be updated over the next several<br />

months as CTU 2009 professors come<br />

on board and the CTU Board of Directors<br />

meets to approve the curriculum.”<br />

Tim says CTU has received a lot of<br />

feedback from students over the past<br />

two years. “The CTU support team really<br />

focuses on those comments to determine<br />

what contesters want to learn and how<br />

CTU can help them to enjoy contesting<br />

more,” he said. “As a result, CTU 2009 is<br />

planning to include several ‘deep dives’<br />

into specifi c contest-operating techniques.<br />

We are working on some ‘lab’ environments<br />

along with demonstrations to help<br />

convey the information.”<br />

He also noted that CTU 2009 plans call<br />

for building upon K5ZD’s acclaimed CTU<br />

2008 presentation on contesting ethics.<br />

“Expect to see CTU 2009 take on ethics<br />

discussions in small working groups,<br />

which will spur conversation and learning<br />

among the attendees,” he explained,<br />

adding that discussions would emphasize<br />

contest rules.<br />

Other CTU presentations will address<br />

optimum contest station design with an<br />

increased focus on ergonomics. The<br />

program will include discussion regarding<br />

what technical specifi cations really mean<br />

to contesters who want a “good” radio.<br />

“CTU 2009 is looking such topics such<br />

as CW Skimmer and software-defi ned<br />

radio (SDR) applications and may include<br />

presentations on these timely topics,” Tim<br />

says.<br />

He further notes that the CTU 2009<br />

team is looking into ways to incorporate<br />

papers that will discuss Field Day technical/interference<br />

topics that could benefi t<br />

home contest stations. Keep an eye on<br />

the offi cial Contest University Web site,<br />

www.contestuniversity.com, for information<br />

updates. In the meantime, if you have<br />

ideas for CTU 2009, pass them along to<br />

NCJ Review: The Elecraft K3<br />

Revisited<br />

A year ago, NCJ presented a contester’s<br />

perspective on a pre-production version of<br />

the new Elecraft K3 (“NCJ Reviews: The<br />

Elecraft K3 — First Impressions,” <strong>Sep</strong>/Oct<br />

2007 NCJ). The review radio was great, but<br />

it lacked some important features in terms of<br />

both hardware and fi rmware. This article updates<br />

those fi rst impressions, commenting<br />

on production version differences, added<br />

components and features, the assembly<br />

and support experience and published lab<br />

tests. It also editorializes a bit on software<br />

defi ned and modular radio experiences that<br />

might be of importance to contesters.<br />

Production Release<br />

Subsequent to the fi eld test review, Elecraft<br />

released many additional items, fi rst<br />

to the testers and then, after ironing out<br />

the wrinkles, to general availability. When<br />

the first K3 production run shipped in<br />

October 2007, the radio included a 100W<br />

power amplifi er, hardware noise blanker<br />

and a higher-precision TCXO. Rigs were<br />

available either factory-assembled or as a<br />

no-solder semi-kit. Later, Elecraft released<br />

a full-function sub-receiver, additional fi lters<br />

and many fi rmware upgrades. The last<br />

included FM, ESSB, auto notch, selectivity<br />

presets, diversity receive and continuous<br />

improvement of nearly everything. Delivery<br />

delays have declined to about three<br />

months, and Elecraft continues to work on<br />

production processes in order to reduce<br />

the backlog.<br />

Elecraft zealots report deliveries on the<br />

company refl ector (elecraft@mailman.<br />

qth.net) and track them via an independent<br />

Wiki, www.zerobeat.net/mediawiki/<br />

index.php. The Wiki includes product<br />

descriptions and resource material. By<br />

unoffi cial count, Elecraft had shipped more<br />

than 1800 K3s through <strong>Sep</strong>tember 2008.<br />

Hardware Additions and Corrections<br />

Very few updates were needed to bring<br />

fi eld test units up to production standards. I<br />

made most of the modifi cations in the fi eld,<br />

and today I can barely distinguish between<br />

my fi eld test unit (serial no 12, June 2007)<br />

and the full-production radio I built in April<br />

2008 (serial no 744).<br />

The most significant feature absent<br />

from my fi eld test radio was the 100 W<br />

power amplifi er. The K3’s PA is considerably<br />

lighter than the one in the K2, and<br />

it’s very easy to install. The heat sink is<br />

entirely inside the K3 case, cooled by two<br />

large, rear-mounted fans. These variablespeed<br />

fans are temperature controlled and<br />

6 November/December 2008 NCJ<br />

quieter than those in my laptop. I literally<br />

never hear them.<br />

The K3 PA has very level power output,<br />

thanks to a strong ALC algorithm that<br />

evolved nicely during fi eld testing. Power<br />

foldback in response to high reflected<br />

power is gradual and effective. Below an<br />

SWR of 2.5:1, I can get 100 to 120 W output<br />

on 160 through 6 meters. An informal<br />

check at 3.5:1 showed 50 W out. If you<br />

reduce the target power below 13 W, the<br />

100 W PA shuts down altogether, and you<br />

have a very effi cient QRP rig.<br />

Sub-Receiver<br />

The most important addition in the<br />

wake of the K3’s initial release is the<br />

KRX3 sub-receiver. Initially, Elecraft was<br />

not satisfi ed with signal isolation between<br />

the main rig and the prototype KRX3.<br />

The manufacturer delayed shipment for<br />

several months while it designed a full<br />

wraparound steel enclosure, tested it and<br />

got it into production. The delay was well<br />

worth it. The sub-receiver is, as advertised,<br />

every bit as good as the main receiver. In<br />

fact, its additional shielding may make it<br />

slightly more immune to external noise<br />

and unwanted signals than the alreadyoutstanding<br />

primary receiver.<br />

The sub-receiver has its own DSP, synthe-<br />

Figure 1 — The KRX3 sub-receiver open; the KPA3 power amplifi er is at top center.<br />

sizer, noise blanker and sockets for up to fi ve<br />

crystal roofi ng fi lters. Although some owners<br />

have equipped the KRX3 with a full fi lter<br />

complement, matching the main receiver, I<br />

haven’t found that necessary. So far, I am<br />

just using the included 2.7 kHz fi ve-pole fi lter.<br />

Since ultimate selectivity is DSP-derived,<br />

this is acceptable except in the presence of<br />

very strong, nearby signals.<br />

The 2.7 kHz fi lter is essentially indistinguishable<br />

from the 2.8 kHz eight-pole fi lter<br />

in my main receiver except when attempting<br />

diversity reception. Because of different<br />

delays through those fi lters, there is a funny<br />

phase shift that’s quite audible in the headphones<br />

when the two receivers are tuned<br />

to the exact same frequency. This latency<br />

disappears when listening to different frequencies,<br />

as in a DX pileup, my primary use<br />

for the sub-receiver. Phase shift is not an<br />

issue when the two receivers are equipped<br />

with matching fi lters. I intend to reconfi gure<br />

my fi lters so that the two receivers have<br />

some in common — probably 2.7 and 1.0<br />

kHz. Although it’s not diffi cult to add and<br />

exchange fi lters, the KRX3 does introduce<br />

additional disassembly to this process.<br />

The K3 is no longer a svelte eight<br />

pounder. The heavily shielded KRX3 has<br />

pushed a fully-loaded K3 up to almost ten<br />

pounds. Some people like that, since the


adio no longer budges when you’re stabbing<br />

buttons. I haven’t had that problem<br />

since Elecraft went to softer rear rubber<br />

feet, but it certainly feels “beefi er” now.<br />

Instability or Continuous<br />

Improvement?<br />

Contesters are always looking for an<br />

edge. In the past, we’ve looked most often<br />

for antennas, accessories, operating tricks<br />

and station-integration techniques while<br />

our transceivers and amplifi ers remained<br />

relatively static. Perhaps we would add the<br />

occasional, non-sanctioned “magic modifi -<br />

cation.” Few of us can justify the expense<br />

of a new rig each time a manufacturer<br />

makes an incremental improvement, so<br />

most of us have tended to wait 5 or 10<br />

years for an entirely new generation radio<br />

that could entice us to write the big check.<br />

The K3 changes this paradigm.<br />

As described in my “fi rst impressions”<br />

article, the K3 is highly modular. You can<br />

buy what you need today and add options<br />

to fi t evolving needs and budget later. The<br />

firmware driving this software-defined<br />

radio changes frequently, adding new<br />

features and performance enhancements<br />

— all for free!<br />

A few critics have declared their intention<br />

to “wait until it is stable” before<br />

investing in a K3. They will have a long<br />

wait. Elecraft shows no sign of abandoning<br />

its continuous engineering program.<br />

Updating is safe and easy, and that’s one<br />

of the radio’s most endearing features to<br />

progressive contesters. Fortunately, the<br />

manufacturer rarely “breaks” anything<br />

along the way. The notion that a radio must<br />

be static in order to be stable is simply<br />

obsolete, in my opinion.<br />

Assembly and Support<br />

As part of the process in developing the<br />

K3 assembly manual, Elecraft assembled<br />

the fi eld test radios itself. My second K3 —<br />

a production unit — was a kit, and I was<br />

delighted with the assembly experience.<br />

As is typical with Elecraft kits and manuals,<br />

there were many “ah-hah!” moments.<br />

It took about 10 to 12 hours to assemble<br />

the kit, including the PA, taking my time and<br />

recording notes for this article. The only<br />

diffi cult part was attaching the front-panel<br />

assembly to the chassis the fi rst time. Lacking<br />

good leverage points to push on, I found<br />

it tricky to align several long headers and<br />

get the stiff, new connectors to mate. With<br />

reasonable care and patience, though, it<br />

came together without incident. After two<br />

subsequent disassemblies, the connectors<br />

have loosened up enough so that it’s now<br />

easy to reassemble.<br />

The field test sub-receiver went together<br />

in a few hours. The sub includes<br />

its own DSP board, which goes inside the<br />

front-panel module. This requires partial<br />

disassembly of that unit. The sub-receiver<br />

also includes its own synthesizer module,<br />

Figure 2 — The KRX3 installed.<br />

Figure 3 — The KPA3 installed.<br />

G4AON with permission<br />

hardware noise blanker, optional generalcoverage<br />

band-pass fi lter board and a few<br />

other small boards. (I declined a second<br />

general-coverage board; one is fi ne for<br />

casual SWLing.)<br />

There was one step that required caution<br />

— nesting the fully assembled KRX3<br />

module into the radio among a half-dozen<br />

miniature coax interconnects. It only took<br />

a few careful minutes, though, and as the<br />

cables acquired a “set,” subsequent insertions<br />

became easier.<br />

As I anticipated in my earlier article, Elecraft<br />

support for the K3 has been superb.<br />

Supplicants using the company-sponsored<br />

refl ector frequently enthuse about sameday<br />

and even weekend responses. Many<br />

issues get resolved even faster with help<br />

from non-employee correspondents. Expectations<br />

are so high that it’s occasionally<br />

amusing to see people grumble when an<br />

Elecraft with permission<br />

Elecraft staffer actually takes a day off!<br />

Integration<br />

The K3 is proving to be every bit as<br />

fl exible as forecast in earlier reviews. For<br />

example, there are at least three ways to<br />

extract band data for antenna, fi lter and<br />

accessory switching:<br />

♦ Top Ten Devices, Unifi ed Microsystems<br />

and Elecraft KRC2 decoders accept<br />

BCD data from the ACC connector.<br />

♦ The KRC2 interfaces with Elecraft’s<br />

proprietary AuxBus.<br />

♦ KRC2, microHAM and other station<br />

controllers support serial port frequency<br />

communication, and a menu option confi<br />

gures the K3 to send frequency data<br />

periodically without prompting from logging<br />

software.<br />

The K3 has proven easy, safe and clean<br />

to set up for FSK, AFSK, PSK, FM, transverter<br />

use, multiple headsets, sound cards,<br />

IF output, receive antenna input/output,<br />

diversity reception with fl exible antenna options,<br />

and more. You can confi gure the K3 to<br />

use serial port RTS and DTR lines as FSK,<br />

CW keying or PTT inputs. You can build a<br />

cable to let the K3 bandswitch amps like<br />

the Yaesu Quadra. Transformer coupling<br />

and various other devices protect I/O lines<br />

against overload, hum and RFI. My only<br />

integration nitpick is that the many sockets<br />

are densely packed on the rear apron; you<br />

may have to unplug some connectors in<br />

order to reach others. Take the time to do<br />

this rather than tugging on the cables!<br />

Software and accessory vendors are<br />

jumping on the K3 bandwagon. SoftRock<br />

offers a custom SDR buffer amp for the<br />

K3, and N8LP sells a full panadapter kit.<br />

Top Ten, microHAM, US Interface and<br />

NCJ November/December 2008 7


others offer custom cables to connect<br />

their decoders, keyers and controllers.<br />

MicroHAM’s multi-device Router software<br />

provides explicit support for the K3.<br />

The logging programs WinTest, N1MM<br />

Logger, DX4WIN, Winlog 32, Logger32,<br />

DXLab, WriteLog and MacLogger DX all<br />

recognize the K3, as do the rig-control<br />

programs Ham Radio Deluxe, N4PY,<br />

N3FJP, TRX-Manager and DXLab. Rose<br />

Kopp, N7HKW, makes custom rig covers<br />

and carrying cases. Nifty Accessories<br />

publishes a laminated, spiral-bound,<br />

quick-reference guide.<br />

Lab Tests and Reviews<br />

Press reviews of the K3 have been quite<br />

favorable:<br />

♦ Performance guru Rob Sherwood,<br />

NCØB, published his measurements of the<br />

K3 in February 2008, and it topped the 75+<br />

rigs on his “Receiver Test Data” chart (see<br />

www.sherweng.com/table.html). Rob<br />

measured a minimum noise fl oor of –138<br />

dBm, two-tone third-order IMD dynamic<br />

range of 95 to 101 dB at 2 kHz spacing<br />

and blocking dynamic range of 140 dB at<br />

100 kHz spacing. Rob is well known for his<br />

groundbreaking critiques of radios and the<br />

measurement techniques used to assess<br />

them. At Dayton in 2007 he focused on<br />

the poor transient response of most thencurrent<br />

DSP radios. Elecraft improved the<br />

K3 AGC to a level that Rob describes as<br />

“perfect” against his lab test that aggravates<br />

a receiver with nanosecond-range pulses. 1<br />

In 2008 he came down on intermodulation<br />

and harmonic distortion in RF power and<br />

audio amplifi ers. It will be interesting to see<br />

which vendors respond most quickly and<br />

effectively to his concerns.<br />

The ARRL review appeared in April<br />

2008 QST and is available to League<br />

members at www.arrl.org. It corroborates<br />

the Sherwood tests within a dB or<br />

so and notes 132 to 139 dB blocking gain<br />

compression, 98 dB fi rst IF rejection and<br />

109 dB image rejection on 20 meters. The<br />

review said, “Overall receiver performance<br />

is right up there with the best radios the<br />

Lab has ever measured, and this is the<br />

fi rst receiver we’ve tested with better than<br />

100 dB IMD dynamic range at the closer<br />

signal spacings.”<br />

In its review, the RSGB’s RadCom called<br />

the K3 “an impressive radio” and “one of the<br />

leading radios for close-in dynamic range<br />

and with excellent features.” The RadCom<br />

review judged the K3 “an ideal radio for use<br />

at home, Field Day or DXpeditions.”<br />

Dave Johnson, G4AON, has published<br />

an extensive online review with detailed<br />

product description, his own informal test<br />

results, photos and scope plots (www.<br />

astromag.co.uk/k3/).<br />

Operating Results and Feedback<br />

The K3 is almost becoming a cult radio.<br />

Perhaps the most visible endorsement was<br />

8 November/December 2008 NCJ<br />

the record-setting February 2008 VP6DX<br />

Ducie Island DXpedition, which used K3s<br />

exclusively to make 183,686 contacts. The<br />

VP6DX team reported, “The outstanding<br />

receiver and transmitter characteristics allow<br />

us to run two positions simultaneously<br />

on any band — even the very narrow 30<br />

meter band — with absolutely no interference.<br />

Good design makes the complex<br />

appear simple: the ins and outs of this<br />

sophisticated radio were quickly mastered<br />

by the operator team, none of whom had<br />

seen a K3 before the expedition.”<br />

At Field Day 2008, the K6NV 2A group<br />

(MLDXCC + Team Truckee) ran three K3s<br />

in a fi re lookout with no inter-station interference.<br />

Most participants were new to the<br />

K3 and had received little or no briefi ng.<br />

They enjoyed the rig from the start, but I<br />

did fi nd myself inserting hints from time to<br />

time to demonstrate features the others<br />

had not yet discovered.<br />

WØYK and AE6Y took three K3s to<br />

Aruba, where they joined W6LD and<br />

KX7M in a 4333-QSO multi-two operation<br />

in the 2008 CQ World Wide WPX CW as<br />

P4ØL. Although they had two radios and<br />

two operators at each position, they often<br />

had the second op listening on the main<br />

K3 sub-receiver for in-band mults. WØYK<br />

remarked that conditions were poor.<br />

the noise level, and the superiority of the<br />

K3 receiver really made a difference in<br />

letting us make at least some contacts,”<br />

he said afterward. “Two of our four operators<br />

had never used a K3. Not long into<br />

the contest, most of us avoided using the<br />

PROII because the K3 was so much more<br />

pleasant to listen with.”<br />

WØYK went on to say, “The exceptional<br />

dual receive in the K3 provides outstanding<br />

ability to simultaneously run and<br />

search and pounce the same band.” He<br />

judged the enhanced radio “a joy to use<br />

with negligible learning curve.”<br />

The P4ØL gang used some external<br />

audio switching to achieve a high level of<br />

operator coordination and station fl exibility.<br />

Operators said they also look forward<br />

to planned ability to use the main and<br />

sub-receivers on different bands. They<br />

complained that some front-panel controls<br />

are still locked out while transmitting. This<br />

situation has been improving since fi eld<br />

testing, however.<br />

N5RZ, K5OT and K5TR teamed up for<br />

the 2008 ARRL June VHF QSO Party<br />

using a K3 as the 6 meter radio. They<br />

made 1392 QSOs on 6 meters, noting<br />

that the K3 performed well. They forecast<br />

increased 6 meter contest activity, thanks<br />

to the emerging trend of top-level contest<br />

rigs to include 6 meter capability.<br />

What’s Left?<br />

The “to-do” list at Elecraft remains long,<br />

even though the K3 is now almost feature<br />

complete with respect to its original specifi<br />

cation. It seems so easy to add features<br />

through fi rmware that requests for refi nement<br />

never cease, and Elecraft listens very<br />

well. Some planned additions include:<br />

♦ digital modes other than FSK, AFSK<br />

and PSK 31 2<br />

♦ a band-display panadapter 3<br />

♦ variable-bandwidth roofi ng fi lters<br />

Conclusions<br />

The K3 continues to delight and amaze<br />

its users. The promised feature set is<br />

nearly complete, but regular updates offer<br />

continuous improvement that contesters<br />

demand. The radio is a self-contained,<br />

software-defined radio that does not<br />

require an external computer. It’s a “mustconsider”<br />

radio for contest and DXpedition<br />

rig selection. For many of us, the decision<br />

is a no brainer. Another manufacturer may<br />

leapfrog Elecraft some day, but in 2008<br />

the K3 looks like the hands-down winner<br />

in cost vs performance, size, weight, fl exibility<br />

and absolute performance.<br />

The Birth of the Louisiana<br />

Contest Club<br />

It seemed a “contesting vacuum” existed<br />

here in Northeast Louisiana, where very<br />

few hams regularly participated in contesting.<br />

Mark, K5ER, and I were the most<br />

active HF contesters in the area. We had<br />

learned from one another what two rookies<br />

could learn but had only reached a pretty<br />

low plateau in terms of our contesting skills<br />

and knowledge. Sometime in the late fall of<br />

2006, we learned that Tim, K3LR, had organized<br />

the fi rst Contest University (CTU)<br />

in conjunction with Dayton Hamvention®.<br />

With enthusiasm and no mercy, Mark<br />

twisted my arm into planning a road trip<br />

to CTU and Dayton in 2007.<br />

Thus began our quest to put Northeast<br />

Louisiana on the contest map. We wanted<br />

contesters everywhere to recognize that<br />

Louisiana had some competitive operators<br />

and stations. Among Louisiana’s hams are<br />

many acknowledged and skilled Amateur<br />

Radio contesters; some of them have even<br />

won national and world contesting awards.<br />

W5WMU, AA5AU and KC5R certainly<br />

have been recognized across the US for<br />

their multi-op, RTTY and QRP contesting<br />

accomplishments.<br />

After Dayton 2007, Mark commented<br />

that simply attending CTU and spending<br />

time in the Contest Super Suite were worth<br />

the trip. With no contest mentors near<br />

home, we found it hard to believe that we<br />

could sit there and discuss station design<br />

and contest tips with the likes of K1TTT,<br />

K8CC and K5ZD or catch W3LPL in the<br />

hall discussing antenna-stacking theory. It<br />

was almost overwhelming. We went home,<br />

put what we had learned into action and<br />

saw our scores increase.<br />

For 2008, we looked forward to returning<br />

to Dayton to visit with the friends we had<br />

made and to learn more. Visiting the Contest<br />

Super Suite and seeing most major clubs<br />

represented, we realized one of our problems:<br />

DX, public service and other groups<br />

regularly met around our state, but there were<br />

no gatherings of experienced contesters. We<br />

later met with several other Louisiana hams,<br />

including KI5XP, NA5Q and KC5R, and they<br />

expressed the same sentiments.<br />

During the conversation that followed,<br />

we all pretty much looked at each other<br />

and said, “If nobody else, then how about<br />

us?” A very rough outline of the state was<br />

penciled onto a napkin (Mark’s favorite<br />

writing tablet), and active contesters were<br />

pinpointed. As the evening progressed<br />

(and pizza consumed), we transitioned<br />

from “Should we?” and “How can we?”<br />

and “Is it worth it?” to an attitude of “We<br />

probably should” and “Yes, we can!” and<br />

“Chomps Boo-TAY,” and our motto is<br />

“Laissez les contest roulez!” (Let the<br />

design and artwork.<br />

fi nally, “You bet we did it!” Lots of smiles<br />

and handshakes followed, and what was<br />

just an idea in May now is a reality.<br />

There was a lot of fi nger pointing in<br />

Dayton as to who were the biggest “suckers”<br />

— that is, who would be the initial<br />

offi cers of the new club. As it turned out<br />

the elected offi cers are K5ER, president;<br />

Scott Dickson, W5WZ<br />

KI5XP, vice president; W5WZ, secretary/<br />

treasurer; W5WMU, director, and NA5Q,<br />

director and webmaster. The LCC would<br />

never have gotten off the starting blocks<br />

without this enthusiastic group that exchanged<br />

countless e-mails as the constitution,<br />

by-laws and other organizational<br />

matters were ironed out.<br />

K5ER really spearheaded the drafting<br />

of the constitution. He started with some<br />

Yankee 1 documents, and then whittled<br />

away to meet our needs. The fi rst draft<br />

circulated just three days after returning<br />

from Dayton. W5WZ worked on locating<br />

the club’s geographical center by geocoding<br />

and mapping all ham radio call signs<br />

in Louisiana, Texas, Arkansas and Mississippi<br />

found in Super Check Partial to<br />

fi nd active contesters. NA5Q and KI5XP<br />

offered valuable suggestions, some of the<br />

best coming via e-mail well after midnight.<br />

To NA5Q goes the credit for the artwork<br />

and design of our mascot, which my wife,<br />

KW5MOM, named “Chomps Boo-TAY.”<br />

The Louisiana Contest Club was formally<br />

organized at the Leesville, Louisiana hamfest<br />

on August 9, 2008. Charter members<br />

signing the club constitution and by-laws<br />

their contesting skills and strategies<br />

while allowing them to share their collective<br />

knowledge and experiences through<br />

mentoring. The LCC is a special-purpose<br />

Amateur Radio club devoted to the pursuit<br />

of operating and technical excellence. Our<br />

goals are simple:<br />

� To promote the fun, satisfaction and<br />

competitive thrill of radio contesting<br />

� To assist members in developing their<br />

operating and technical skills<br />

�To foster increased friendly competition<br />

and sportsmanship<br />

� To become a competitive force in Amateur<br />

Radio contesting club competition<br />

� The LCC has chosen to mark the center<br />

of its membership circle near Marksville,<br />

Louisiana, at coordinates 31.226894°<br />

north latitude and 91.944580° west<br />

longitude. Consequently, the entire<br />

populated area of Louisiana along with<br />

much of southwestern and west-central<br />

Mississippi and southeastern Texas fall<br />

within the 175-mile radius imposed by<br />

many contest rules (see www.louisianacontestclub.org/maps.htm).<br />

Solving the Long Rotator Cable<br />

Problem for Larger Rotators<br />

Editor’s note: An earlier version of this<br />

article appeared in April 2008 edition of<br />

"The Black Hole," the newsletter of the<br />

Society of Midwest Contesters. It’s being<br />

published here with the author’s permission<br />

— Al Dewey, KØAD<br />

Hams have struggled for years with<br />

fi nding cost-effective methods to address<br />

the necessity of long rotator cable runs. A<br />

variety of methods have been proposed<br />

for the ubiquitous Ham-M family. For short<br />

runs of up to 100 feet or so, the traditional<br />

method has been to use a specifically<br />

designed cable having two AWG 18 wires<br />

for the brake solenoid/motor common and<br />

six AWG 22 wires for direction sensing,<br />

limit switches/motor windings and starting<br />

capacitor. For longer runs, more expensive<br />

cables with AWG 16/20 or even AWG 10/14<br />

wire are available at a substantial increase<br />

in cost.<br />

Other hams have substituted multiple<br />

runs of Romex house wiring cable, which<br />

generally starts at AWG 14. Some also<br />

suggest adding a “booster” transformer.<br />

This transformer is wired in series with the<br />

leads from the control box to the brake solenoid/motor<br />

common. The key is to make<br />

sure the voltage adds to (boosts) rather<br />

than subtracts from (bucks) the normal 24<br />

V ac output of the control box.<br />

Hams who have used larger rotators,<br />

such as prop pitch motors, seem to have<br />

relied upon one of two methods to deal<br />

with long cable runs. The fi rst uses large<br />

wire. At my station I have a run of approximately<br />

500 feet from the shack to the top<br />

of the tower. When I used an M 2 Orion,<br />

the AWG 12 Romex was barely adequate.<br />

When I upgraded to a prop pitch, I couldn’t<br />

get any rotation at all. Doubling up with<br />

another run of AWG 12 — for an equivalent<br />

cross-section of AWG 9 — still left the<br />

antenna motionless. With the increase in<br />

the cost of copper, further investment in<br />

wire seemed unwise.<br />

A second approach to dealing with long<br />

runs of cable has been to install a remotely<br />

controlled power supply at the tower base.<br />

At the 2007 Dayton Hamvention®, Green<br />

Heron offered such a unit. Whether commercially<br />

manufactured or homebrewed,<br />

this generally requires a run of cable to<br />

carry 120 or 240 V ac to the tower. In addition<br />

to the safety and code considerations<br />

involved with such high voltages external<br />

to the shack, there is a complication with<br />

many of the newer-style control units.<br />

Both M 2 and Green Heron use pulsed<br />

power to produce a ramped startup<br />

and slowdown of the antenna to reduce<br />

Figure 1 – Wiring diagram for using<br />

large rotators with long cable runs.<br />

stresses on the tower and rotator. This<br />

means the pulsed-control circuitry needs<br />

to be housed at the base of the tower. This<br />

is a duplication of cost, however, since the<br />

circuitry already exists at the control end<br />

and generally cannot be separated from<br />

the display electronics of these units.<br />

I verifi ed that my prop pitch worked by<br />

temporarily connecting the control box at<br />

the base of the tower. Stationing my XYL<br />

outside to run the box during a contest, however,<br />

seemed undesirable, since I choose to<br />

Terry Zivney, N4TZ/9<br />

n4tz@arrl.net<br />

enter the single-operator category.<br />

Being short of funds and wanting to<br />

keep my spouse happy, I opted for a third<br />

approach (Figure 1). This is nothing more<br />

than a version of the bucking voltage used<br />

years ago with the Ham-M. Because the<br />

prop pitch and newer Orions use dc motors,<br />

I inserted an inexpensive spare 12 V<br />

dc power supply in series with the negative<br />

(common) lead at the control box. The<br />

positive lead of the external power supply<br />

is connected to the negative lead at the<br />

control box. The wire from the rotator that<br />

went to the negative lead at the control<br />

box now goes to the negative lead of the<br />

external power supply.<br />

I’m using a cheap Samplex switching<br />

supply purchased some years ago from<br />

RadioShack for a packet radio no longer<br />

in use. You can buy one for less than $100,<br />

far cheaper than a long run of Romex or<br />

an external Green Heron controller. All<br />

features of the control box remain unchanged,<br />

including the pulsed dc for the<br />

speed control. It really is that simple.<br />

As a side note, my TIC rings nicely turn<br />

my 10/15 duobanders through 450 feet of<br />

AWG 18 wire (doubled to be equivalent<br />

of AWG 15) and one dc motor. The same<br />

ring with a full-size 5 element 20 and 2<br />

element Cushcraft 40 needed the Romex<br />

treatment (doubled AWG 14 to be equivalent<br />

to AWG 11) to enable rotation with the<br />

standard TIC box.<br />

Today, I would use the smaller wire<br />

and boost the voltage with an external dc<br />

power supply. TIC uses only two power<br />

wires, and switches the polarity inside<br />

the control box, so a small modifi cation<br />

would be required inside the control box<br />

to insert the boosting voltage at the correct<br />

location.<br />

Distributing Receiving<br />

Antennas — Part 2<br />

In late 2007 the VP6DX Ducie Island<br />

DXpedition project team began working<br />

out the designs of low-band receiving<br />

antennas. Some expedition requirements<br />

replicate those of contest stations, especially<br />

SO2R, multi-op and Field Day stations.<br />

The solutions tested on Ducie may<br />

help contesters improve their low-band<br />

receive abilities. The fi rst installment of<br />

this two-part article appeared in the <strong>Sep</strong>/<br />

Oct 2008 issue of NCJ. It described the<br />

detailed system requirements for the<br />

low-band receiving antennas at Ducie as<br />

well as the approach we chose to meet<br />

these requirements. This installment describes<br />

the band-pass fi lter, switching and<br />

preamplifi er implementation we used to<br />

optimize the design as well as the results<br />

we achieved and some ideas for potential<br />

improvements.<br />

Band-Pass Filter Splitter<br />

The homebrew band-pass fi lter splitter<br />

box accepted as an input the signal from<br />

one direction of a Beverage. The circuit<br />

extracted to separate outputs — one for<br />

160 and two for 80/75. These fi lter splitters<br />

were installed at the central switching<br />

hub. Figures 6a and 6b, available in an<br />

expanded version of this article at www.<br />

ncjweb.com/bonus.php, show the circuit.<br />

It consists of two W3LPL band-pass<br />

fi lters — one for 160 and one for 80/75,<br />

in parallel. The 80/75 meter output fed a<br />

Mini-Circuits splitter to clone two copies,<br />

one for the CW operator and one for the<br />

SSB operator.<br />

The W3LPL fi lters can be paralleled<br />

because of their relatively high stop-band<br />

impedance. 1 The W3LPL design also tolerates<br />

a fairly wide range of input and output<br />

impedances. That’s important because<br />

temporary antennas may not adhere<br />

closely to the nominal design impedance<br />

and because receiver impedances can<br />

vary substantially from nominal values.<br />

The component values used for these<br />

fi lters are for a nominal 50 Ω impedance.<br />

We didn’t have time to scale and test the<br />

fi lters for a Z o of 75 Ω. Figure 6c shows<br />

the measured response of the assembled<br />

fi lter splitter in a 75 Ω environment. Despite<br />

the Z o deviation, the package shows very<br />

good rejection and tolerable in-band loss.<br />

The 160 meter output exhibited 2.1 to 2.7<br />

dB in-band loss between 1800 and 1900<br />

kHz and 47 to 56 dB rejection between<br />

3500 and 3850 kHz. The 80/75 meter<br />

output exhibited 4.8 to 12 dB in-band loss<br />

between 3500 and 3850 kHz, and 76 to 99<br />

12 November/December 2008 NCJ<br />

dB rejection from 1800 to 1900 kHz.<br />

Note that the 80/75 meter outputs suffer<br />

an additional 3 dB loss because of the passive<br />

splitter used to clone signals on that<br />

band for the two operating positions. Not<br />

every contest station requires this cloned<br />

output, and the board layout allows the<br />

builder to omit that splitter and its accompanying<br />

F connector. For contest stations<br />

with two operators listening on each band,<br />

the board layout permits the 160 meter<br />

fi lter output also to be cloned with a passive<br />

splitter. The rejection values assume<br />

particular importance in protecting the<br />

downstream electronics from out-of-band<br />

transmitted signals picked up by these<br />

antennas. More on this topic later.<br />

Construction Notes<br />

Eric laid out this circuit on a doublesided<br />

board. To improve isolation between<br />

the two bands, he placed the 160 meter<br />

fi lter on one end of the board, and the<br />

80/75 meter fi lter on the opposite end.<br />

Figure 2 shows the assembled board. A<br />

gas tube surge arrestor with a low fi ring<br />

voltage provides some input protection<br />

against lightning.<br />

Because a filter splitter could live<br />

outdoors, construction employed temperature-compensated<br />

capacitors in an<br />

attempt to maintain performance over a<br />

wide temperature range. A unit was stored<br />

in the refrigerator’s freezer compartment<br />

for a few hours to allow the components to<br />

stabilize around –10 C. Measurements at<br />

this temperature showed no material difference<br />

in performance compared to room<br />

temperature. This range of temperatures<br />

would not be expected at Ducie Island but<br />

could occur at a contest station or other<br />

expedition sites.<br />

Trimmer capacitors don’t possess the<br />

temperature stability of fi xed capacitors.<br />

The W3LPL fi lter design relies on tweaking<br />

the toroid windings in order to tune each<br />

stage of the fi lter for a fl at passband over<br />

the desired frequency range. Eric used a<br />

network analyzer to view the passband’s<br />

characteristics while making adjustments<br />

to the spacing between turns on the toroids<br />

(other methods can also be used).<br />

After attaining a satisfactory passband,<br />

coil dope locked the turns in position.<br />

Remotely Controlled Switch<br />

For expediency, the VP6DX Ducie Island<br />

expedition used six (two per operator)<br />

off-the-shelf Ameritron RCS-10 remote<br />

control coax switches. The RCS-10 is<br />

Eric L. Scace, K3NA<br />

k3na@arrl.net<br />

George Cutsgeorge, W2VJN<br />

a large transmit power-level unit using<br />

SO-239 connectors. The design team<br />

anticipated a 700 meter control cable run<br />

between the remote switching hub and the<br />

selector boxes at each operating position.<br />

Shielded, stranded-wire Ethernet cable<br />

connected the selector box to the remote<br />

switch. This cable is available relatively inexpensively<br />

in bulk (eg, 1500 meter reels).<br />

Reels are about as heavy as one strong<br />

person could safely manage while unloading<br />

in the surf. To speed assembly at the<br />

island, we pre-installed and tested RJ45<br />

connectors on the cable, operator selector<br />

boxes and remote switch boxes.<br />

A signifi cant voltage drop occurs over<br />

this length of control cable. We exploited<br />

an advantage of the RCS-10 system by<br />

confi guring its control box to accept 24<br />

V dc. Measurements and calculations<br />

prior to departure showed that over this<br />

distance the control box and Ethernet<br />

cable — with two paralleled conductors<br />

per control signal line — would deliver<br />

suffi cient power to run the relays in the<br />

remote switch box. Behavior at the island<br />

confi rmed the calculated design. We used<br />

adjustable replacement laptop power supplies<br />

as a 24 V dc source with a battery<br />

backup for use during generator outages.<br />

To save assembly time, supplies and<br />

equipment were pre-wired with PowerPole<br />

connectors. (Blue and black connector<br />

colors and prominent labels warned operators<br />

that these lines carried 24, not 13,<br />

volts.) West Mountain Radio’s RIGrunner<br />

dc distribution boxes joined a power supply<br />

with subtending equipment such as<br />

these remote coax switch control boxes.<br />

(With care, the RIGrunner’s PowerPole red<br />

connector housings can be replaced with<br />

another color, such as the blue we used<br />

to fl ag 24 V dc lines.)<br />

Not all remotely controlled antenna<br />

switch designs work properly for this<br />

application. The remote switch must not<br />

short unused antenna ports to ground,<br />

as these signals might be used by the<br />

second receiver. 2<br />

While the RCS-10 units offered an<br />

off-the-shelf solution that could meet our<br />

needs, quality control and signal isolation<br />

were relatively weak aspects of this<br />

particular equipment. As delivered, the<br />

hardware exhibited many poor solder<br />

joints. One switch box had to be completely<br />

disassembled and re-soldered to<br />

work properly. Fortunately we were able to<br />

perform this major undertaking at home,<br />

as the manufacturer rivets the SO-239


connecters to the chassis. Replacement<br />

rivets were not on hand, and reassembly<br />

after repair took a lot of fi dgeting in close<br />

quarters with short screws, nuts and lock<br />

washers.<br />

The RCS-10, like many remotely controlled<br />

switches, uses a rotary switch with<br />

a mechanical stop to select the desired<br />

antenna. This stop prevents the operator<br />

from easily comparing signals between<br />

the two antennas at either end of the<br />

switch range, however. Sometimes the<br />

mechanical stop can be removed or the<br />

switch replaced with a model without a<br />

stop. If that’s not possible, arrange the<br />

choices so the two affected antennas are<br />

the least likely to be compared. At Ducie<br />

Island we sequenced the switch selections<br />

in this order (clockwise): 195°, 2<strong>25</strong>°,<br />

270°, 305°, 15°, 45°, 90° and 1<strong>25</strong>°. The<br />

195° direction, used only near sunrise<br />

for long path, was never compared to the<br />

1<strong>25</strong>° direction, as that direction was in full<br />

daylight at the time.<br />

Preamplifi er<br />

The output of each remotely controlled<br />

switch fed a co-located, low-noise preamplfi<br />

er. The preamps compensated for<br />

losses in the system. The highest frequencies<br />

— 3750 to 3850 kHz — exhibited the<br />

greatest losses:<br />

� 1.7 dB for 100 meters of RG-6 cable<br />

between the antenna feed point and<br />

the fi lter splitter input. Only the 90°/270°<br />

Beverage had this long run to the central<br />

switching hub.<br />

� 6 to 12 dB in the W3LPL band-pass fi lter<br />

plus Mini-Circuits splitter.<br />

� 12 dB for a 700 meter run of RG-6 from<br />

the remote switching hub to the operating<br />

position.<br />

Other parts of the system, including the<br />

coax shield current choke and the antenna<br />

switch, exhibited negligible losses. Overall<br />

losses added up to 20 to 26 dB between<br />

the antenna feed point and receiver on<br />

75 meters. Beverage signal output on the<br />

80/75 meter antenna at the feed point is<br />

greater than that on the 160 meter Beverage,<br />

which helps offset a bit of this loss. To<br />

overcome most of these losses we used<br />

the DX Engineering RPA-1 preamp, which<br />

provides about 16 dB gain, 3.5 dB noise<br />

fi gure and +43 dB third-order intercept.<br />

Voltage fed down the RG-6 from the radio<br />

tents provided power to the preamp. This<br />

preamp draws 140 mA at a nominal 13 V<br />

dc, yielding a nominal internal resistance<br />

of 93 Ω. Belden fl ooded RG-6 coax offers<br />

about 5 Ω per 100 meters of dc loop<br />

resistance (center conductor plus shield).<br />

With the 700 meter runs planned for Ducie<br />

Island, 35 Ω of cable resistance would<br />

drop the voltage delivered to the preamp<br />

by about 3.5 V, below its operating range<br />

of +10 to +18 V dc. To compensate, the<br />

higher supply voltage of 24 V dc used for<br />

the remotely controlled switch also fed<br />

the preamps.<br />

Preamp Protection<br />

As mentioned earlier, one must protect<br />

the preamp input from strong signals<br />

picked up while transmitting. At Ducie<br />

Island up to seven full-power transmitters<br />

could be on the air simultaneously. Three<br />

systems worked together to provide this<br />

protection: the band-pass fi lter splitter,<br />

power interruption and in-band rejection.<br />

The band-pass fi lter splitters knocked<br />

down signals outside the operator’s own<br />

band. For a preamp used on the output of<br />

a 160 meter remotely controlled switch,<br />

for example, the 160 meter portion of the<br />

band-pass fi lter splitter reduced signal<br />

levels for transmitters on any other band by<br />

about 50 dB, low enough not to bother the<br />

preamp. After the fi lter splitter, the preamp<br />

remained exposed only to the operator’s<br />

own 160 meter in-band transmit signal.<br />

When the operator transmits, he is not<br />

listening; therefore, the preamp can be<br />

turned off during transmission. A homebrew<br />

“power interrupter” sat next to the<br />

radio. It injected the preamp supply voltage<br />

(24 V dc in this implementation) into the<br />

two RG-6 coax runs (one for each receiver)<br />

to the remote switching hub. Figure 7,<br />

available available in the expanded article<br />

at www.ncjweb.com/bonus.php, shows<br />

the circuit. A 13 V dc control line, when<br />

grounded, triggers two relays to remove<br />

the preamp supply voltage from the coax,<br />

disabling the remote preamps for both<br />

receivers. On Ducie Island the microHam<br />

microKeyer II’s LNA PTT port manipulated<br />

this control line. We confi gured the microKeyer<br />

II to turn off the preamp about 20<br />

ms before triggering the transmitter’s PTT.<br />

This guarantees that the preamp would<br />

be off well before transmission starts (the<br />

use of VOX was forbidden at VP6DX; the<br />

microKeyer would not connect the microphone<br />

to the transmitter until the operator<br />

stepped on the footswitch).<br />

The vast majority of amateur transceivers<br />

provide mediocre isolation between<br />

their antenna port(s), including their receiver<br />

input ports. Isolation is typically in<br />

the range of 40 to 45 dB. When transmitting<br />

100 W via the transmit antenna port,<br />

the radio also leaks a signal at about 10<br />

mW (10 dBm or S9 + 77 dB) from the<br />

receive antenna port. That signal leakage<br />

includes harmonics, IMD products and<br />

their phase noise sidebands, typically 50<br />

dB below the leaked carrier (–40 dBm or<br />

S9 + 27 dB).<br />

The power interrupter box uses smallsignal<br />

relays not only to interrupt the voltage<br />

supplied to the preamps but to short<br />

the receive antenna ports to earth ground.<br />

This additional function substantially reduces<br />

signal leakage. For the 160 meter<br />

operator, the band-pass fi lter and preamp<br />

power interrupter together protect the<br />

remote preamps from all the other on-site<br />

transmitters. The 80 meter CW preamps<br />

remain exposed to one transmitter, however.<br />

That’s the 75 meter SSB transmitter,<br />

with signals falling within the passband<br />

of the band-pass fi lters preceding the 80<br />

meter CW preamps. In similar fashion, the<br />

75 meter SSB preamps remain exposed to<br />

the 80 meter CW transmitter’s signal.<br />

George, W2VJN, solved the remaining<br />

problem of in-band rejection with notching<br />

fi lters. These fi lters place a sharp notch<br />

(greater than 40 dB) on the unwanted<br />

transmitter’s frequency while introducing<br />

little additional loss (less than 1 dB) to the<br />

desired receive frequencies. George discusses<br />

the design and implementation:<br />

In December 2007, K3NA asked if I<br />

knew of a way to operate on 75 and 80<br />

meters with separate stations for the<br />

upcoming Ducie Island operation. Eric<br />

was concerned about the close proximity<br />

of the Beverage antennas to all of the<br />

transmitting antennas. I had been working<br />

on some new stub ideas, and I knew they<br />

could provide 15 to 20 dB of attenuation<br />

between the CW and the SSB ends of the<br />

band. This seemed somewhat marginal.<br />

In addition there would be 5 to 8 dB of<br />

on-frequency attenuation, which seemed<br />

excessive as the signal levels coming from<br />

the Beverage antennas would already be<br />

quite low. A quick preliminary design of<br />

a simple band-stop fi lter with the Elsie 3<br />

program showed a possible solution.<br />

A three-element Butterworth design<br />

could provide 40 dB attenuation at the<br />

null frequency and would not attenuate<br />

the desired listening frequency by more<br />

that a dB or so. The inductor requirements<br />

were modest, as a Q of 75 or more at the<br />

operating frequency would be adequate.<br />

Two of the inductors were in the 50 to 60<br />

µH range, while one was in the less than<br />

500 nH range. A few commercially available<br />

inductors having values in the desired<br />

µH range were obtained, and a selection<br />

was made based on Q measurements.<br />

The design then was tweaked to use the<br />

selected inductors. The nH chokes that<br />

we tested had miserably low Qs and were<br />

deemed unsuitable. A few turns around a<br />

type 2 powdered iron toroid core showed<br />

more promise, and that’s what we used in<br />

the fi nal design.<br />

To optimize the null depth, each element<br />

(tuned circuit) must be adjustable.<br />

Shunt elements L 1 and C 1 require only a<br />

small variation in capacitance for tuning,<br />

and trimmer capacitors can do the job.<br />

The trimmers were padded with a series<br />

capacitor and a shunt capacitor to reduce<br />

the sensitivity of tuning as the null is very<br />

sharp.<br />

Construction was done on readily<br />

available prototype PC boards, as there<br />

was not enough time to do custom work.<br />

NCJ November/December 2008 13


Figure 1 — W2VJN in-band notching<br />

fi lter schematic diagram.<br />

Simple point-to-point wiring is adequate.<br />

Four units were built to meet the requirements,<br />

two for 80 meters and two for 75<br />

meters.<br />

Figures 1 and 3 detail construction<br />

and performance details, and<br />

Table 2 provides a list of components.<br />

These units needed to be rugged enough<br />

to withstand the long journey via air, sea<br />

and ground to the operating positions on<br />

Ducie Island. Small aluminum boxes were<br />

used. The boards were mounted on four<br />

threaded standoffs. Type F connectors<br />

were used according to the 75 Ω system<br />

requirements.<br />

A three-element fi lter is simple enough<br />

so that formal methods are not required,<br />

and alignment can be done by alternately<br />

adjusting each tuned circuit. Watching the<br />

loss at the desired pass frequency and the<br />

null depth on a network analyzer while<br />

adjusting allows a good compromise to be<br />

found. Figure3 shows the sweep response<br />

of one of the units.<br />

As Built on Ducie Island<br />

As mentioned earlier, we did not build<br />

out the entire system at the island. With<br />

just a single receiver in the Elecraft K3 radios,<br />

we required only half of the switching<br />

matrix. We built the second parallel leg for<br />

the 45°/2<strong>25</strong>° Beverage. While this antenna<br />

performed superbly, we did not feel very<br />

strongly that we needed the second leg<br />

on the other Beverages. We also worried<br />

that adding the second leg — for example<br />

to the 15°/195° Beverage — might introduce<br />

a gap in coverage between the two<br />

Beverage arrays, especially on 80/75 with<br />

its narrower beamwidths. That gap would<br />

run right through the middle of both the<br />

US and Europe.<br />

Results<br />

Overall this system performed superbly.<br />

There’s no question that it improved signalto-noise<br />

ratio. The Beverage systems<br />

delivered superior s/n ratios compared<br />

to the transmitting antennas for these<br />

bands. Dietmar, DL3DXX, summed up the<br />

situation one evening around midnight,<br />

after he had fi nished a lengthy 160 meter<br />

operating session with Europe on a band<br />

fi lled with static: “No Beverages? Then no<br />

14 November/December 2008 NCJ<br />

Figure 2 — Notching fi lter assembled unit.<br />

Figure 3 — Typical notching fi lter measured response.<br />

QSOs,” he said.<br />

An operator could tell when sunrise occurred<br />

in the Caribbean by comparing the<br />

45° and 15° Beverages. The static level on<br />

the 45° Beverage dropped signifi cantly as<br />

sunrise moved across the Caribbean and<br />

D-layer absorption attenuated QRN from<br />

the thunderstorms in that region. The 15°<br />

Beverage still heard plenty of static from<br />

sources within its main beam.<br />

This was the fi rst DXpedition where we<br />

felt we could hear anyone calling us on<br />

Top Band. In fact, at times we could hear<br />

stations calling us much better than they<br />

could hear us.<br />

In terms of reducing QRM and dividing<br />

pileups, the Beverages’ patterns appeared<br />

to behave exactly as expected. The ARRL<br />

International DX Contest (CW) occurred<br />

early in the DXpedition, and station location<br />

is part of the contest exchange. If a W6<br />

called but was weaker on the 15° Beverage<br />

(which covered California) and louder on<br />

the 45° Beverage, we could be certain he<br />

would be in the Eastern US, not on the<br />

West Coast. The transition area where<br />

stations exhibited equal strength on these<br />

two particular Beverages was distinct and<br />

narrow — from Texas through Arkansas<br />

to Indiana and Michigan. These distinct<br />

patterns meant that the operator could<br />

focus on East Coast US stations during


their sunrise enhancement using the 45°<br />

Beverage that displayed relatively weak<br />

response to closer, louder West Coast stations.<br />

In similar fashion the 15° Beverage<br />

favored Scandinavia, Eastern Europe and<br />

western Siberia over Western Europe — a<br />

big advantage for us right after Ducie Island<br />

sunset. We had a two to three hour window<br />

to work these remote parts of the world on<br />

unfavorable polar paths before their local<br />

sunrise. On the next DXpedition, I’m defi -<br />

nitely looking forward to trying directional<br />

diversity reception with a similar Beverage<br />

array feeding the K3’s dual receivers!<br />

The system also supported three operating<br />

positions without problems. During<br />

the second half of the DXpedition demand<br />

for 75 meter SSB from North American<br />

and even Europe dropped off. On some<br />

nights we removed the notch fi lters and ran<br />

just one station on 80/75 meter CW/SSB.<br />

The freed-up operating position became<br />

the second station on 30 meters.<br />

Further, we avoided damage from on-air<br />

transmitters. Not only were the preamps<br />

adequately protected, the operators could<br />

not detect the presence of any other on-air<br />

transmitter.<br />

The 80/75 meter QSO total represents a<br />

new record for a DXpedition, and the 160<br />

meter total stands second in the record<br />

books behind 5A7A’s 7653 QSOs, which<br />

included many Europeans worked on a<br />

short hop from Libya (see Table 1).<br />

The 440 meter long east-west Beverage,<br />

also with a narrower beamwidth, appeared<br />

to be too long; the main beam seemed too<br />

narrow. Stations from the extreme southern<br />

Caribbean or northern South America<br />

(P4, YV) often had poor signal-to-noise<br />

ratios compared to others further north<br />

(good copy on the 45° Beverage) or south<br />

(closer to the center east-west Beverage’s<br />

main beam). Callers from Australia and<br />

Southeast Asia left similar impressions to<br />

the west. Milt, N5IA, and Robin, WA6CDR,<br />

later rerouted the eastern half of that Beverage<br />

to form a very shallow bent V shape<br />

in order to widen the beam. Unfortunately,<br />

few stations called us from these areas,<br />

making it diffi cult to form an opinion about<br />

any improvement.<br />

The system enabled us to cover all<br />

directions. Europe, North America and<br />

Asia made up 98 percent of our 160<br />

meter contacts and 94 percent of 80/75<br />

meter totals. With the exception of some<br />

long-path contacts with Eastern Europe,<br />

two or three single-wire Beverages could<br />

handle many of these contacts. One might<br />

question whether the results justifi ed the<br />

additional hardware for and incremental<br />

work to install two-wire Beverages and<br />

the fourth east-west Beverage. While small<br />

in percentage terms, we were happy to<br />

work the DXers represented in those 1300<br />

QSOs. The long path QSOs on the 195°<br />

and 2<strong>25</strong>° Beverages with Ukraine and<br />

European Russia stations on Top Band,<br />

across more than 22,000 km and into their<br />

afternoon daylight, represent an unforgettable<br />

DXing experience.<br />

Based on DXpedition experience in<br />

Burma (Myanmar), the team also brought<br />

materials to construct a low dipole for listening<br />

to high-angle signals on 160. This receive<br />

antenna was never built, however, since<br />

none of the Top Band operators found any<br />

opening where they might be able to better<br />

copy signals using a high-angle antenna.<br />

The ability of each low-band operator to<br />

choose his listening direction without concern<br />

for the impact on another operator was<br />

much appreciated by the low-band team.<br />

The Beverage distribution system delivered<br />

better-than-expected signal levels<br />

to the receivers. When comparing signals<br />

received on the transmit antenna to the<br />

same signals on the appropriate Beverage,<br />

the absolute signal strengths were about<br />

the same. Static levels, however, dropped<br />

dramatically on the Beverage. The transceiver’s<br />

internal preamp was unnecessary.<br />

Signal suckout did not occur. Operators<br />

never detected a change in receive signal<br />

level when one of the other operators selected<br />

the same receiving antenna.<br />

Potential Improvements<br />

Every implementation can inspire ideas<br />

for improvements. Readers contemplating<br />

the use of some of these techniques in their<br />

own stations might consider the following<br />

possibilities and, we hope, will share their<br />

results with the rest of the contesting/DXing<br />

community. If someone wants to help<br />

us with some of these ideas, we will be<br />

very grateful for the assistance!<br />

General<br />

Weatherproofi ng any kind of box-mounted<br />

coax connector takes time and care,<br />

and both can be in short supply during a<br />

DXpedition, during Field Day or during the<br />

rush to prepare a station for a contest. An<br />

alternate approach would place box(es)<br />

inside a NEMA IP67 enclosure using cable<br />

glands to seal out the weather.<br />

For fi eld connections, consider using<br />

watertight RJ45 connectors with an IP67<br />

environmental rating. Although more<br />

costly, these connections speed assembly<br />

time.<br />

RG-6 coax paired with a CAT-5 cable<br />

and molded into a single assembly suitable<br />

for outdoor use is available. This cable<br />

appears to be more costly than individual<br />

runs of RG-6 and CAT-5. However, in a<br />

situation where assembly time is limited,<br />

the time saving may justify the incremental<br />

expense. Flooded cable is preferable in the<br />

outdoor environment.<br />

Beverage Array<br />

If planning to use parallel Beverages<br />

with their narrower beamwidths, consider<br />

using more Beverage systems — for example,<br />

fi ve or six two-wire systems for ten<br />

to twelve directions. This choice affects the<br />

choice of selector switch. If space permits,<br />

parallel Beverages are preferable to long<br />

Beverages.<br />

Coax Shield Current Chokes<br />

To avoid cabling errors in the fi eld, label<br />

the coax connector to go to the antenna<br />

and the connector for the coax run to the<br />

receiver.<br />

Band-Pass Filter Splitter<br />

For those wishing to share a receiving<br />

antenna on three bands, Frank, W3LPL,<br />

reports success in paralleling three of his<br />

band-pass fi lters — for example, 160, 80<br />

and 40 — without too much in-band loss.<br />

We plan to investigate a modifi ed design<br />

for 75 Ω characteristic impedance.<br />

Remotely Controlled Switch<br />

One can easily design a smaller,<br />

better-performing switch unit using sealed<br />

small-signal relays. Constructing this unit<br />

with F connectors would eliminate the<br />

large number of F-to-UHF adapters used<br />

at Ducie Island. Daisy chaining a pair of<br />

relays and careful board layout can boost<br />

isolation among the various antennas. A<br />

single box could contain both switches for<br />

the two receivers on a band, dramatically<br />

reducing the number of coax jumpers.<br />

We plan to investigate sending selection<br />

signals down the coax, along with dc<br />

power. This would eliminate the expense<br />

and construction time associated with<br />

NCJ November/December 2008 15


the control line. If selection signals were<br />

transmitted down the coax, the same box<br />

could include the dc power injection/interruption<br />

tasks as well as shorting to earth<br />

ground the receiver antenna ports when<br />

transmitting. One should be able to create<br />

such a box of a smaller volume than two<br />

RCS-10 control boxes.<br />

LED indicators identifying the selected<br />

switch position can speed acceptance<br />

testing and troubleshooting in the fi eld.<br />

Use bright LEDs to enhance visibility on<br />

sunny days. Additionally, include a pair of<br />

test points for quick fi eld checks of voltage<br />

delivered to the box.<br />

An operator selection box with a circle<br />

of illuminated push-buttons would permit<br />

quick comparison of short and long-path (or<br />

any other two non-adjacent choices). Two<br />

such circles of buttons would allow control<br />

of antennas for both receivers; this should<br />

include a “slave” button to allow both receivers<br />

to use the same antenna selection.<br />

Chassis-mount F connectors often loosen<br />

frequencies around 3802 and 3784 kHz,<br />

worked well for our DXpedition. In a typical<br />

contest station the notch needs to be<br />

adjusted to track the transmitter around the<br />

band, and George’s fi lter design certainly<br />

permits such adjustments. We haven’t<br />

tried doing this in real time, however.<br />

Notes<br />

1 In contrast, other band-pass fi lter designs such<br />

as those by W3NQN have very low stop-band<br />

impedances. When paralleled, the low stopband<br />

impedance of one band’s fi lter short<br />

circuits the desired frequencies for the input<br />

of the other band — and vice versa.<br />

2 Shorting one output of the band-pass fi lter<br />

splitter might also increase somewhat<br />

the attenuation of the other output(s),<br />

an undesirable result in this application.<br />

This observation is speculative, as the<br />

condition was not tested when measuring<br />

the performance of the fi lter splitter.<br />

Simplifying the Four-Square<br />

The four-element square antenna<br />

array of quarter-wave vertical elements<br />

with quadrature current drive — or “foursquare”<br />

— has become very popular<br />

among low-band DXers. For many of us,<br />

however, its site area requirements have<br />

been a negative factor in its adoption.<br />

More compact versions generally require<br />

more complex drive circuitry, such as<br />

that in Figure 2a, and this can also be a<br />

disincentive.<br />

Have you been put off building a<br />

four-square array by the multiple towers,<br />

elaborate ground system, complex feed<br />

circuits and fi nicky adjustment procedure?<br />

Here’s an alternative that works as well<br />

as the real thing but only needs one<br />

tower, a single radial ground system, no<br />

phasing lines and no L networks, and it<br />

tunes easily.<br />

Construction<br />

Photo 1 (right) shows one of the four<br />

elements that are deployed every 90°<br />

around a single quarterwave-tall support.<br />

Element shape and size is chosen to<br />

simultaneously minimize horizontally<br />

polarized radiation, provide suitable<br />

spacing between points of maximum<br />

current and present a 50 Ω feed point<br />

impedance 1 . Ideally the support should<br />

be insulated to reduce the possibility of<br />

pattern distortion by current induced by<br />

the radiators, but there are ways to make<br />

grounded towers transparent at the array’s<br />

working frequency 1, 2 . I use three 6-meter<br />

steel scaffold poles to support my 80<br />

meter array. The elements are made of<br />

inexpensive steel-core satellite coaxial<br />

cable because this has minimum stretch<br />

and provides a large effective diameter<br />

to minimize loss with light weight. At<br />

the mast base the wires terminate on a<br />

piece of insulating-sheet material and<br />

connect — inner and outer conductors<br />

together — via feed-through insulators at<br />

the control box.<br />

A ground system of buried radials, as<br />

many and as long as you can fi t onto the<br />

site, radiates from the array’s center. The<br />

element wires are pulled away with 2 mm<br />

Nylon twine to posts, trees or buildings.<br />

You can change the shape of the elements<br />

if necessary to reduce the pulling radius,<br />

but it will degrade the radiation pattern.<br />

That takes care of the construction details.<br />

Now, the theory.<br />

How it Works<br />

The elements are effectively 0.4 λ<br />

when the dielectric loading by the cable<br />

maximum current on each element are<br />

0.<strong>25</strong> λ from the top, which makes their<br />

effective spacing about 0.15 λ. If we drive<br />

this array as a conventional close-spaced<br />

four-square it requires relative currents<br />

of 1.3 A at 0°, two of 1 A at -120° and 1<br />

A at -240° for the rear, center and front<br />

elements, respectively. Because all these<br />

currents return to a common ground<br />

point, the Earth connection loss is only<br />

that due to their vector sum of 0.8 A at<br />

-230°. Consequently the ground system<br />

is less important from a loss standpoint<br />

than for a conventional four-square with<br />

individual ground returns. Conventional<br />

all-driven-element operation requires a<br />

feed system like that in Figure 2. Here L 1 /<br />

C 1 handle input matching for the feeder. L 2 /<br />

C 2 and L 3 /C 3 are dual-purpose networks<br />

that determine phase delay and voltage<br />

ratio.<br />

The 90° coaxial phasing lines are used<br />

to convert the voltages at their input ends<br />

into corresponding currents in the elements.<br />

In this case, because the elements<br />

are longer than 0.<strong>25</strong> λ, we also need to<br />

match them with series capacitors C 4 to C 7<br />

of equal value in order to keep the VSWR<br />

low on the phasing lines.<br />

We do not have to do it this way!<br />

Simplifying the Feed System<br />

If we don’t drive the front and rear<br />

elements, we have a parasitic array. By<br />

adjusting the matching capacitors in this<br />

confi guration, we can control the current<br />

amplitude and phase. In fact we can<br />

find values that will give the optimum<br />

amplitudes that we could have calculated<br />

for all-driven-element operation. Because<br />

this array is relatively close spaced the<br />

Figure 3 — Direction control and tuning<br />

circuit for the G3LNP four-square.<br />

18 November/December 2008 NCJ


optimum phase angles for the currents<br />

in the elements tend to correspond with<br />

the optimum amplitudes. This can be<br />

confi rmed by computer modeling, which<br />

shows no difference in the radiation<br />

pattern for either the all driven-element<br />

confi guration or the parasitic confi guration.<br />

The drive circuit now simplifi es to that<br />

in Figure 2B. All we have to add are the<br />

direction-switching relays.<br />

Direction Switching<br />

Unless operating very low power<br />

(QRP), voltages at the ends of the wires<br />

are high and beyond the capability of<br />

conventional relays to handle. Vacuum<br />

relays with changeover contacts might<br />

simplify the circuit, but I found their self<br />

capacitance led to unwanted coupling<br />

between elements. This resulted in poor<br />

directivity. High-voltage dry-reed relays<br />

designed for electro-medical applications<br />

are the only type I have found to be suitable.<br />

These represent the primary expense in<br />

constructing this antenna. High-value<br />

resistors are added to discharge static<br />

electricity from the elements and from<br />

the tower if it is insulated. Figure 3 shows<br />

the switching and drive circuit, which<br />

is built in an ABS weatherproof box as<br />

Figure 4 — Construction detail for the circuit in Figure 3.<br />

in Figure 4. Construction objectives<br />

are to keep the wiring length as nearly<br />

constant as possible for each direction<br />

and to minimize stray capacitive coupling<br />

between elements.<br />

Setting to Work<br />

To tune the array you must be able to<br />

measure the current amplitude in any pair<br />

of adjacent elements at their feed point. I<br />

use 20 turn current transformers, a dualtrace<br />

’scope and a fraction of a watt of<br />

RF input. Low-impedance devices such<br />

as automotive lamps or RF ammeters<br />

should also work. Confi rm that all relays<br />

are working correctly. Set the director<br />

Tips for Tuning a Full-Size<br />

160 Meter Vertical<br />

I’m often asked how to match a quarter-wave<br />

vertical for 160 meters to a<br />

50 Ω transmission line, what to do about<br />

lightning protection and even how to take<br />

RF measurements with powerful AM<br />

broadcast signals in the vicinity. This article<br />

will describe how to make a basic — but<br />

elegant — matching device for a quarterwave<br />

vertical which does additional duty<br />

as a static bleed device and a surge arrestor<br />

with a lightning loop. I’ll also explain<br />

how it’s possible to take the antenna measurements<br />

needed to make the matching<br />

device and to tune the antenna correctly<br />

while in the presence of strong RF from<br />

nearby AM broadcast stations.<br />

Antenna Matching on 160 Meters<br />

I’ve seen antenna matching solutions<br />

that range from just attaching the coax to<br />

the antenna and living with the result to<br />

adding a series capacitor to allow tuning<br />

the antenna over the band or even using<br />

an L network to match the antenna’s approximately<br />

30 Ω to the feed line’s 50 Ω.<br />

Let’s look at a very simple solution that<br />

I’ve found useful.<br />

My own quarter-wave 160 meter vertical<br />

is sort of an inverted L. It rises up from<br />

ground level to 50 feet as a free-standing<br />

aluminum tube. At that point I’ve attached<br />

a #12 wire that slopes upward at a 45°<br />

angle to my 150 foot tower. The system<br />

has 64 buried radials. Fortunately we have<br />

Figure 1 — Connecting the probe to the coax.<br />

excellent ground here. Due to the sloping<br />

wire the antenna’s feed-point impedance<br />

is lower than the theoretical 36 Ω.<br />

What we will attempt to do is tune this<br />

antenna for a 50 + j0 Ω resonance at 1.830<br />

MHz using an LC network. For a capacitor<br />

we will just shorten the antenna length<br />

a small amount to create the necessary<br />

“phantom capacitance.” I don’t like to use<br />

series capacitors, since they’re prone to<br />

fail at high currents and in lightning events.<br />

Then a single inductor across the feed<br />

point is all we need to match the antenna<br />

to the transmission line. This technique is<br />

a great way to handle this sort of matching<br />

situation.<br />

Issues with Nearby AM Broadcast<br />

Station RF<br />

There are many AM broadcasters in<br />

my area, and one station even operates<br />

on 1700 kHz! These stations place 10 V<br />

peak-to-peak RF onto my antenna during<br />

the day and even more at night. Figure 1<br />

shows how to attach a ’scope probe to the<br />

coax stub going to the Heliax feed line.<br />

Figure 2 shows the scope reading at the<br />

unterminated end of 150 feet of half-inch<br />

50 Ω Heliax. Trying to take an accurate<br />

measurement using any of the impedance<br />

meters available to hams is impossible.<br />

They overload, and some will even blow<br />

their diode bridges, requiring a trip to<br />

the factory. The AIM 4170B analyzer we<br />

Figure 2 — 10V peak-to-peak RF<br />

market at Array Solutions, www.arraysolutions.com,<br />

will not blow up, but simply<br />

hooking it to the feed line won’t let you<br />

take any measurements in the presence<br />

of strong RF either. It does, however, have<br />

a neat feature that can be used to take this<br />

measurement accurately, and we will use<br />

it to help us tune this antenna.<br />

The 10 V peak-to-peak RF represents<br />

0.<strong>25</strong> W of power into 50 Ω. The AIM 4170B,<br />

on the other hand, puts out microwatts of<br />

RF to enable measurements. So, how can<br />

this device override the power that’s showing<br />

up in the antenna system?<br />

When we attach the AIM 4170B to this<br />

antenna and coax and do a scan from 1.5<br />

to 2.5 MHz, we see the plot in Figure 3.<br />

The bold line above the X axis is VSWR.<br />

The lighter line highlighted with squares is<br />

resistance (R), while the lighter line highlighted<br />

with dots is reactance (X).<br />

Due to the RF overload, the plot is full<br />

of noise and totally useless; we need to<br />

alter our measurement technique if we<br />

are to get accurate information to allow<br />

us to adjust this antenna. What we need<br />

is a good broadcast-band high-pass fi lter.<br />

W3NQN makes a superb fi lter for this<br />

purpose, and I connected it to the RF connector<br />

of the AIM 4170B analyzer. Before<br />

using it, however, it’s necessary to null out<br />

its transfer function so the measurements<br />

we take are not affected by it.<br />

High-order fi lters like these have phase<br />

shifts and other linear parameters due to<br />

their design. We must normalize them.<br />

To do this the AIM 4170B has a “custom<br />

calibration” feature. This is the "neat feature"<br />

I mentioned. The software leads you<br />

through a “super” calibration using the<br />

short, open and load technique through<br />

the fi lter over a limited frequency range<br />

of interest. To create a very accurate<br />

calibration table requires lots of sample<br />

points. I used 500 points of measurement.<br />

The software will create a very detailed<br />

Figure 5 — The sidebands show about<br />

1<strong>25</strong> mV of RF still getting through the<br />

fi lter.<br />

calibration table that essentially moves<br />

the measurement point from the analyzer’s<br />

RF connector to the input connector of the<br />

broadcast band high-pass fi lter.<br />

Once the custom calibration is run, it can<br />

be saved in a fi le for future use. Now that<br />

we have the analyzer and fi lter fully calibrated,<br />

we can retest the antenna and coax<br />

system. Figure 4 shows the plot obtained<br />

while scanning through the fi lter. Note that<br />

I added 8× averaging (see the “AVG=8” in<br />

the upper right-hand corner of the trace) to<br />

the measurement to get rid of any residual<br />

noise. This way we can eliminate the effect<br />

on the measurement of the AM broadcast<br />

station’s ever-changing sideband power.<br />

As a further check, I looked at the antenna<br />

through the fi lter with the ’scope.<br />

Figure 5 shows approximately 1<strong>25</strong> mV<br />

peak-to-peak RF is getting through the<br />

fi lter. That’s still pretty high, but the AIM<br />

4170B can handle it.<br />

Adjusting the Antenna to Create the<br />

Phantom Capacitor<br />

To create a “phantom capacitor” as<br />

part of a matching network, we need to<br />

adjust the antenna’s resonant frequency<br />

to make it short or capacitive. Instead of<br />

resonating the antenna at 1830 kHz, we’ll<br />

move its resonant point up in frequency.<br />

Since I don’t care about operating above<br />

1875 kHz, I use 1900 kHz as my target<br />

frequency so the antenna exhibits a capacitive<br />

reactance at 1830 kHz. Using an<br />

L-network program like the Network program<br />

we offer, it’s easy to create a match<br />

for this antenna.<br />

First we need to fi nd the impedance at<br />

our desired frequency. Figure 6 shows a<br />

plot with a vertical line marker at 1830<br />

kHz. The corresponding resistance is 41.6<br />

Ω and the corresponding impedance is<br />

–41.5 Ω (capacitive reactance) at the end<br />

of the transmission line.<br />

To obtain the exact reactance at the antenna<br />

we could take the AIM to the antenna<br />

and measure the input terminals, or we can<br />

just use the “Refer to Antenna” function in<br />

the software, describe the 150 feet of 50<br />

Ω Heliax, the cable loss (a lookup table)<br />

and its velocity factor (also a lookup table).<br />

Plugging these numbers into the software<br />

prompts and rescanning will now give the<br />

measurement as if we were at the feed<br />

point all from the comfort of my air conditioned<br />

shack! The R and X values turn out<br />

to be almost exactly the same as at the<br />

transmitter end of my cable. At 160 meters<br />

this is probable, but you cannot assume<br />

they will be the same at higher frequencies;<br />

they could be drastically different.<br />

The L-network software calculates that<br />

we need a shunt coil of about 5.8 µH to<br />

match this impedance to 50 Ω. Using a<br />

three-inch piece of PVC pipe as a coil<br />

form, I wound 12 turns on it per the network<br />

Figure 7 — The inductor attached<br />

to the insulated vertical element is<br />

grounded at its far end (not seen).<br />

Figure 6 — With the marker at 1830 kHz, R = 41.6 and X = –41.5 (capacitive reactance). The measurement is referred to the<br />

antenna by the AIM 4170B software.<br />

attenuation in the fi lter at these frequencies. Everything above 1.7 MHz is valid.<br />

Figure 10 — The VSWR = 1.03 at 1832 kHz.<br />

software’s coil-design program. Initially you<br />

might want to make the inductor larger<br />

and tap down for the best match. Figure<br />

7 shows the inductor at the base of the<br />

antenna, while Figure 12 is a schematic<br />

diagram of the coax feed system.<br />

Re-running the plot (Figure 8) shows<br />

that we now have matched the antenna.<br />

The inductor acts just like a hairpin match<br />

on a Yagi, and the loss in the coil is only<br />

about 5 W at 2000 W input. But the coil<br />

serves another function: It also works as<br />

a static bleed choke that will defi nitely<br />

help to save your equipment in the event<br />

of a direct or nearby lightning hit. This is<br />

a pretty elegant solution for a matching<br />

device, a static-bleed choke and a surge<br />

arrestor in a single component!<br />

You can make the design even more<br />

lightning proof by adding a loop — or one<br />

turn of copper pipe — to the center conductor<br />

of the Heliax to create a lightning<br />

loop and perhaps even a spark gap from<br />

the vertical element to ground. A suitable<br />

spark gap can be fashioned from bolts<br />

and rounded acorn nuts opposing each<br />

other. The gap is adjusted so that a 700 V<br />

RF signal will not arc. This may be a good<br />

topic for a future article.<br />

Measurement Accuracy?<br />

Figure 9 shows a wideband sweep from 1<br />

to 2.2 MHz. Note that the fi lter’s attenuation<br />

is so large that it perturbs the measurements<br />

below 160 meters. This is fi ne, since<br />

we don’t care about the AM band anymore;<br />

the fi lter’s attenuation of the broadcast<br />

band RF allows the AIM 4170B to take<br />

the measurement on 160. The question<br />

remains: How accurate is the measurement<br />

considering the nearby RF turmoil?<br />

I used a NIST-calibrated PowerMaster<br />

watt/VSWR meter and my ICOM IC-781<br />

transceiver to verify the readings of the<br />

AIM 4170B. The AIM plot, Figure 8, shows<br />

the VSWR is 1.027 at 1832 kHz. Tuning the<br />

IC-781 to 1832 kHz and putting out some<br />

RF, we see in Figure 10 that the calibrated<br />

VSWR meter shows 1.03. That’s pretty<br />

darn close to unity and well within the margin<br />

of error of these measurements. Keep<br />

in mind that some of the other components<br />

in line — amplifi er, coax cables, wattmeter<br />

coupler, etc — could affect the reading.<br />

Now let’s check the bandwidth of the antenna<br />

with the VSWR meter and compare<br />

it with the plot seen in Figure 11. I moved<br />

the VFO to both 18<strong>04</strong> kHz and 1859 kHz<br />

and checked the VSWR with the rig and a<br />

wattmeter. The VSWR meter shows almost<br />

the exact same VSWR readings, and the<br />

bandwidth is exactly the same. As a matter<br />

of fact, these measurements are identical<br />

at higher VSWR.<br />

I’d like to express my appreciation and<br />

gratitude to Grant Bingeman, KM5KG, and<br />

Bob Clunn, W5BIG, for their assistance in<br />

developing this article.<br />

NCJ Profi le: Bob Naumann, W5OV<br />

Tis the season for CQ World Wide and<br />

ARRL November Sweepstakes, while<br />

the qualifying for World Radiosport Team<br />

Championship <strong>2010</strong> in Russia concludes<br />

this spring. Past WRTC operators always<br />

have interesting stories to tell about their<br />

passion for ham radio, contesting and the<br />

social aspects of the hobby. I fi rst met this<br />

month’s profile subject and WRTC-96<br />

participant Bob Naumann, W5OV, in the<br />

fall of 1986. I was 17 at the time and more<br />

than a little intimidated by being invited to<br />

operate at a big multi-multi (K2GL/N2AA)<br />

for the CQ WW SSB Contest. Bob may<br />

not remember, but because I was a little<br />

nervous about the whole thing on Friday<br />

afternoon I said — with N2AA standing<br />

right there — something like, “Gee, thanks<br />

for inviting me up here to watch all this.”<br />

Bob chuckled, as if to say, “What? You’re<br />

here to operate,” while Gene<br />

shook his head and said,<br />

“Hope you didn’t plan on<br />

sleeping.” All it took was a<br />

kind word, and I felt right<br />

at home.<br />

Have you ever at least<br />

once in your life thought, “If<br />

I had a job doing something<br />

involving Amateur Radio,<br />

that would be for me.” Bob,<br />

who now resides in Sachse,<br />

Texas, is an employee of<br />

accessory manufacturer<br />

Array Solutions as well as<br />

a veteran contester. He<br />

started off contesting in New<br />

Jersey, was present for the<br />

salad years of the K2GL/<br />

N2AA operations and then<br />

found himself living in Texas<br />

and concentrating on going<br />

to the Caribbean. Here’s his<br />

story in his own words.<br />

I started in Amateur Radio in 1972<br />

when I was a freshman in high school.<br />

My parents had given me a CB radio as<br />

a graduation present from eighth grade.<br />

One of the friends I made via CB — Sal,<br />

now KM6JD — had a Radio Shack short<br />

wave receiver. He was listening around on<br />

the receiver one day while I was visiting,<br />

and we heard some guys talking. They<br />

were having two-way conversations, but<br />

it wasn’t CB. I asked him what that was,<br />

and he said, “Oh, they’re hams.” I knew<br />

that was for me. We both learned the code<br />

shortly thereafter, and we were licensed<br />

in early 1973 — he as WN2LFC and I as<br />

WN2OVE.<br />

I met my fi rst real contester via a telephone<br />

call. It was on a Saturday morning.<br />

My mother told me some guy was on the<br />

Bob Naumann, W5OV<br />

phone, and he was really angry about my<br />

radio. Oh, boy. Whose TV was I messing<br />

up? Boy was I wrong! He was upset about<br />

my DX60’s key clicks messing up his European<br />

SSB run on 15. He was WB2VYA,<br />

and I stopped transmitting immediately. I<br />

was scared. Of course, he is now KR2Q,<br />

and Doug has been an Elmer to me in<br />

addition to being a very good friend for<br />

35 years.<br />

My fi rst contest operation was Field Day<br />

in 1973, when I operated as WN2OVE/1<br />

while on a family camping trip. I made 66<br />

QSOs. While I was there, I bumped into<br />

some slow-speed CW guys in the New<br />

England Slow Net. This led me into traffi c<br />

handling, where I met most of the big-time<br />

traffi c and contest guys in W2 Land, such<br />

as (then-) WB2RKK, WB2RJJ, WB2FLF,<br />

WA2SRQ and WA2UOO among others.<br />

Then there were the ARRL CD parties.<br />

I loved those contests. I operated Sweepstakes<br />

and DX contests too, but I was<br />

never really too serious about contesting<br />

until 1979 when WB2VYA asked me to<br />

come with him to K2GL’s to see the N2AA<br />

station there. I was overwhelmed. Over the<br />

years I met many people at K2GL’s who<br />

have been most infl uential on my development<br />

as a contester and as a person. Of<br />

course, these included KR2Q and K2GL<br />

as well as operators like N2AA, K2SS,<br />

K2TT, K5NA, K5DU, K2UR, K2TW, K2XR,<br />

K1KI, K3EST, W3ZZ, KU2M, KR2W,<br />

NA2AA, and others. The list includes a<br />

couple of guest appearances by people<br />

like K3LR and W4PA.<br />

Sadly, one of my favorite members of<br />

the K2GL gang left us not too long ago.<br />

He was Dave Rosen, K2GM. Dave also<br />

Scott Robbins, W4PA<br />

provided an opportunity for me to operate<br />

at 4U1UN, which I will never forget.<br />

He had an enthusiasm for life that was<br />

unique. It’s a shame that he’s gone. Away<br />

from the K2GL scene, my relationship with<br />

the other contesters in the Northeast grew<br />

too. Some of those traffi c handlers, such<br />

as N2NT, W2RQ, W2GD and others, were<br />

serious contesters too.<br />

I also met a lot of good friends when I<br />

joined the Yankee Clipper Contest Club. I<br />

met K1AR and K1DG then, along with one<br />

of my closest friends, W2YV. Dave and I<br />

have not spoken in a long time, but he was<br />

one of my best pals for many years. Some<br />

of the people I got to know during those<br />

years have left us too — W2PV, AJ1I,<br />

K2OY, K1EB and — very sadly and most<br />

recently — Stu, KC1F.<br />

Following the K2GL and YCCC days,<br />

I operated with the N2RM<br />

team in Southern New Jersey.<br />

N2RM, N2NC, WM2H,<br />

N2AA, K2TW, N4HY, K3UA,<br />

WT3Q, KA2AEV, K2BM,<br />

N2EA, N2NL, NA2AA, N7BG,<br />

WC4E, K8GL, K3EST, NQ4I<br />

and KR2Q were all part of<br />

that era. We had a lot of fun<br />

(I mean a lot!) and we won a<br />

lot of contests. N2NC and I<br />

became close friends during<br />

that time, and we still room<br />

together in Dayton every<br />

year. Around the same time,<br />

I played golf with K3TUP and<br />

his friends — such as W9XR,<br />

W3GH, VE3EJ, N3BJ, K3UA,<br />

N2NT, WM2H, N5KO et al —<br />

at a few “TUP Opens” in Erie,<br />

Pennsylvania.<br />

Dayton Hamvention also<br />

has had a huge impact on<br />

me, mostly because of those whom I have<br />

met there and continue to see year after<br />

year. My good friend Jim White, K4OJ, was<br />

a fi xture for me in Dayton since the fi rst<br />

time I went there. Of course, Jim’s passing<br />

was tough on me, and I did not go to<br />

Dayton for two years as a result. I have met<br />

so many great people in Dayton over the<br />

years I cannot possibly list them all.<br />

In 1995, I went on my fi rst real DX contest<br />

operation to Antigua with the V26B<br />

multi-multi team. What an exciting time<br />

that was! During that CQ WW Contest,<br />

K3MM and I did something that may have<br />

been unique but certainly was a lot of fun.<br />

I had a 348 hour on 15 SSB, while Tyler<br />

had a 329 hour on 20 at the same time<br />

while we were sitting next to each other.<br />

It was awesome!<br />

The following year, Tyler and I were<br />

NCJ November/December 2008 29


teammates at the 1996 WRTC in San<br />

Francisco. We came in ninth place, but<br />

we beat a lot of really good guys so we<br />

felt vindicated. I have been back to Antigua<br />

numerous times since operating as<br />

V26B with W3CF, WT3Q, KA2AEV, AB2E,<br />

WXØB, W2UDT, N2TK, K3MQH, NM5M,<br />

N3BNA, N2SR, W3FV, K3MM, N3OC and<br />

NA2AA among others. In 1999, K3MM,<br />

K3RA and I did the ARRL CW contest as<br />

a multi-two as V26O (my Antiguan call<br />

sign), and we, at 7.8 M, were beaten by<br />

HC8N, with 8.7 M. Not a bad operation<br />

to lose to.<br />

On another occasion, Brian, N3OC,<br />

and I operated a WPX CW contest from<br />

Antigua as V<strong>25</strong>A. That was a great deal<br />

of fun, and I got to know Brian very well<br />

then too. If you’re doing any kind of contest<br />

operation, N3OC would be a great person<br />

to have on your team.<br />

The last time I operated from Antigua<br />

was in 20<strong>04</strong> as V26DX from the Royal<br />

Antiguan Hotel. KM9M, WXØB, DF2BO<br />

(owner of Optibeam) and I operated the<br />

ARRL SSB contest multi-two, low power<br />

from the hotel, and we made nearly 7000<br />

QSOs. That was really a fun trip because<br />

the XYLs were along (see www.contesting.com/articles/5<strong>25</strong>).<br />

When I moved to Texas in 1996, I continued<br />

to fl y back East to operate from<br />

N2RM a couple of times and more recently<br />

to K3LR. Most of my contest operating in<br />

Texas has been from AA5NT, where we did<br />

multi-two most of the time, enjoying Marian,<br />

N5TVL’s hospitality and having a lot<br />

of fun. I have also operated at K5MR and<br />

WXØB as well as some limited operation<br />

from my own QTH.<br />

A few years ago, I became less and less<br />

enamored with my corporate IT career,<br />

and WXØB needed some help at Array<br />

Solutions. With a lot of arm-twisting on my<br />

part, Jay relented and took me on to help<br />

him on a part-time basis with a couple of<br />

larger commercial deals. Of course, hams<br />

were involved in those deals. KR9U, K1XX<br />

(whom I have known since my YCCC days)<br />

and K3VN were among those I crossed<br />

paths with on those early assignments.<br />

A few months later — and coincidental<br />

with my savings running pretty low — Jay<br />

and his wife Sharon, N5CK, offered me a<br />

full-time position as operations manager<br />

for Array Solutions. I’ve been doing that<br />

job for more than two years now, and it is<br />

a lot of fun. I think that working with ham<br />

radio is a big perk all by itself, but getting<br />

to talk to people I know from contesting<br />

for these many, many years is a big plus<br />

too. When I pick up the phone it could be<br />

K1ZM, ON4UN, K6LA, GW3YDX, W2GD,<br />

N3RD, K5RX, ES5TV, PY5EG or OH2BH<br />

among many others. Through my work<br />

with Array Solutions I had the opportunity<br />

to go to Friedrichshafen, Germany, for the<br />

2008 Ham Radio show. While there, I at-<br />

30 November/December 2008 NCJ<br />

tended the Bavarian Contest Club’s <strong>25</strong>th<br />

anniversary buffet dinner. What a great<br />

experience. I met many new friends there<br />

like P43JB, DL2CC, DL6LAU, DL6RAI<br />

and DL4LAM.<br />

It doesn’t get much better than that. I<br />

am most grateful to Jay and Sharon for the<br />

opportunity they have given me.<br />

Thanks, Bob! It really doesn’t get much<br />

better. The common interest we all have in<br />

contesting is as much a source of pleasure<br />

to those of us who participate in it as the<br />

operating itself. Until next issue, see you<br />

Workshop Chronicles<br />

As Plato and others who followed have<br />

suggested, necessity is the mother of invention.<br />

This perspective powered some<br />

recent work in Texas involving the NR5M<br />

rebuild. Here are the details.<br />

Star guying (sometimes called “star<br />

bracket” guying) is sometimes overlooked<br />

as a solution to stacking large antennas,<br />

but when KR7X ran the numbers for us<br />

on the benefi ts derived from using them,<br />

W2GD and I decided to locate star guys<br />

under every KØXG orbital-ring rotator<br />

and OWA-stacked Yagi at George’s station.<br />

The strengthening capabilities were<br />

wonderful, but when confronted with twice<br />

the number of guys, we obviously had to<br />

do something.<br />

A few minutes of inspecting commercial<br />

installations using star guying showed that<br />

they merely “stacked” the EHS guys top to<br />

bottom. Some EQ plates I looked at held<br />

as many as 12 guys! Of course, with standard<br />

Rohn hardware (all of George’s highband<br />

towers are standard Rohn — <strong>25</strong>G,<br />

45G or 55G), this was not an option.<br />

The seemingly obvious solution would<br />

be to add more holes to the Rohn EQ<br />

plates. This was not a workable idea,<br />

however, since we didn’t want to weaken<br />

the system. The simple adapter seen in<br />

Figure 1 was a better answer — two fl at<br />

steel plates welded at 90° with appropriate<br />

mounting holes for attaching them to the<br />

existing EQ plates, plus the requisite turnbuckles.<br />

After welding, these pieces were<br />

hot-dipped galvanized. Figure 2 shows<br />

these adapters in use. We’re in the process<br />

of building some larger ones for use on the<br />

big PiRod tower, which will hold 80 meter<br />

stacks and utilize star guys.<br />

We recently decided to build and install<br />

an 80 meter four-square system at<br />

George’s contest station — specifi cally,<br />

a pair of phased four-squares. While noo-<br />

the NR5M rebuild.<br />

Figure 2 — Star guy adapters in use.<br />

dling around various ideas and confi gurations<br />

and making a visit to K3LR’s to<br />

see what Tim was using, we decided to<br />

utilize HBX-56 towers. How to insulate<br />

them remained the question of the day,<br />

however. W2GD suggested we look at the<br />

BX tilt-over base option. As soon as I saw<br />

that, I knew using the homebrew round<br />

rod insulators I’d built for another client a<br />

few years ago would work fi ne with them.<br />

Figure 3 shows a fi nished insulator.<br />

Basically, three parts, all of equal size,<br />

comprise each insulator; these replace<br />

the steel tube normally used. Each consists<br />

of 1.5 inches of solid fi berglass rod<br />

glued inside 2-inch fi berglass tubing and<br />

encased in UV-rated PVC for protection<br />

and to allow a more precise fi t to the BX<br />

channel. All fi berglass was purchased from<br />

Max-Gain Systems in Atlanta. I followed<br />

the suggestion of Max-Gain owner Allen<br />

Bond and used construction adhesive to<br />

glue all components together.<br />

Each of the three insulators<br />

required drilling<br />

five holes. Because of<br />

the separate angles for<br />

each tower leg’s channel,<br />

we had to use a<br />

rotating head for precision.<br />

This meant employing<br />

the services of<br />

a machine shop. A local<br />

ham did that for me,<br />

and I hand carried the<br />

insulators to Texas in<br />

a separate suitcase. In<br />

today’s economically<br />

strapped airline world,<br />

this was costly, but it was<br />

cheaper than shipping<br />

them! This attention to<br />

Figure 3 – Rod insulators were used to<br />

insulate the tower.<br />

detail paid off, as we installed every one<br />

of the required 24 insulators easily and<br />

smoothly. Figure 4 shows a fi nished tower<br />

base before ground radial installation.<br />

Walking around any station in which one<br />

has had a hand in building usually brings<br />

back memories or feelings of satisfaction.<br />

In Texas, I’m fond of joking that I’ve<br />

learned size matters. That said I’m equally<br />

proud of the simple and small, yet elegant,<br />

solutions we’ve created to problems like<br />

these. I’m sure we’ll encounter others, and<br />

necessity once again will inspire us.<br />

Contest Tips, Tricks and Techniques Gary Sutcliffe, W9XT<br />

Strengths and Weaknesses<br />

In sports competition you always want<br />

to apply your strengths against your opponent’s<br />

weaknesses. While radio contests<br />

are not direct head-to-head confrontations,<br />

it still makes sense to make the best use<br />

of your strengths and to minimize the effects<br />

of your weaknesses. This installment<br />

of CTT&T looks at what some contesters<br />

consider to be their strengths and weaknesses<br />

and how they adjust their operating<br />

techniques accordingly.<br />

Geography and Location<br />

Unlike most sporting events where<br />

the players are on the same fi eld, radio<br />

contesting has a very uneven playing<br />

fi eld. Different regions experience different<br />

propagation. Within a given region,<br />

geography can have a big effect on station<br />

performance. Everyone wants to be on top<br />

of the big hill in the middle of a salt marsh,<br />

but few of us are that fortunate.<br />

From North America, New England and<br />

Maritime Canada enjoy an advantage<br />

toward Europe with its multiplier-rich population<br />

centers. K1IR considers his Massachusetts<br />

QTH as one of his strengths,<br />

especially on the low bands. Jim says that<br />

his one-acre lot is larger than many hams<br />

have, but compared to his competition in<br />

the multi-single class, it’s quite small. He<br />

has built his station to take maximum advantage<br />

of low-band propagation.<br />

K1IR is limited to one tower, and a 4<br />

element 40 meter beam dominates it. He<br />

has a wire 4-square for 80 meters. The<br />

wooded areas surrounding the property<br />

allow for low-band, low-noise receiving<br />

antennas. Jim says the combination of<br />

these antennas and his location help him<br />

to outscore larger stations in more disadvantaged<br />

locations.<br />

W7WHY considers being atop a hill as<br />

his biggest strength. He has good shots<br />

to Europe and Africa. There is a bay at the<br />

bottom of the hill, so Tom gets the extra<br />

advantage of the water refl ection. Despite<br />

having only 2 element monobanders, he<br />

could hear stations his friends in the valley<br />

could not hear during the last sunspot<br />

maximum. Tom would like to put up bigger<br />

antennas but says the winter winds at the<br />

top of the hill are bad, and he has lost a<br />

lot of antennas because of them.<br />

I also feel my biggest strength is my<br />

location on the side of a hill. I have great<br />

shots to Europe as well as to the south and<br />

to the west. The takeoff toward Europe is<br />

especially favorable, as the terrain drops<br />

off until it reaches a small lake. Working<br />

into the Northwest is a problem, however,<br />

because I’m looking into the rest of the<br />

hill.<br />

32 November/December 2008 NCJ<br />

Continental geography is both a strength<br />

and a weakness for ZS6AA. Being a relatively<br />

rare multiplier is a big help, and a lack<br />

of local stations reduces QRM. Andrew’s<br />

location is also a disadvantage, however.<br />

There are not a lot of short to mediumrange<br />

stations to work when propagation<br />

is poor.<br />

Andrew has found that operating high<br />

power is not too effective, given his<br />

country’s 400 W limit. On the other hand,<br />

running low power hurts him when North<br />

America and Europe have their beams<br />

pointed at each other, and he’s off the<br />

side. To compensate Andrew uses SO2R<br />

and good S&P techniques. He prefers CW,<br />

which can help to offset the low-power<br />

disadvantage.<br />

PY2NY also feels geographic location<br />

is a plus for him, but he credits good<br />

antennas for 40 and 20 meters too. Vitor<br />

says one of his weaknesses is inadequate<br />

fi ltering for SO2R and having only a single<br />

tower.<br />

Antennas<br />

There are probably very few contesters<br />

who didn’t wish they could improve their<br />

antennas, at least on some bands. N2WN<br />

is no different. Although Jules says his antennas<br />

are good, there’s always room for<br />

improvement. To compensate, he tries to<br />

improve the effi ciency of the ones he has.<br />

Most of them are fed with buried Heliax.<br />

W9RE feels that 20 meters is his weak<br />

point, both in domestic and DX contests.<br />

Mike thinks he may have resolved part of<br />

his problem by taking down the top two antennas<br />

on his tower. He hopes to do better<br />

on 20 without the 40 meter beam there.<br />

To compensate for 20 meters, Mike had<br />

tended to stay on 15 meters longer. Now<br />

he’s going back to 20 earlier to catch the<br />

1700 UTC European openings. Mike says<br />

15 meters is a problem in domestic contests<br />

because he cannot rotate his lower<br />

beam to the west. Mike is always working<br />

on antennas to make improvements.<br />

My own towers are fairly short — 50 feet<br />

and 60 feet. I would like more and taller<br />

towers, but the cost — and especially the<br />

upkeep — have kept me from going that<br />

route. Except on 15 and 10 when conditions<br />

are good, I usually don’t get many<br />

big runs going, so I have to S&P a lot. I<br />

compensate by having multiple antennas<br />

on as many bands as possible.<br />

For example I have a TH7 on one tower,<br />

and a stack of 2×3 element tribanders on<br />

the other. I can feed them in any combination.<br />

Sometimes I have all of them<br />

pointed in the same direction. Other times<br />

the stack is pointed in one direction and<br />

the TH7 in another. This makes it quick to<br />

snag stations in different directions without<br />

having to turn a beam.<br />

Different antennas help with different<br />

locations or conditions. For example, the<br />

top A3 of the stack is better toward the<br />

Pacifi c than the TH7. It probably has less<br />

gain than the TH7, but it is a bit higher<br />

and defi nitely quieter. The TH7 is better<br />

toward Africa.<br />

K2SX is in an antenna-restricted location.<br />

He’s hidden a Butternut vertical in the<br />

woods and has been experimenting with<br />

hidden wire antennas. Dennis runs 1 kW<br />

compensate for the lack of antenna gain.<br />

Operating<br />

Multi-op stations often can put in operators<br />

the same way a coach makes<br />

substitutions in a game. K1IR notes that<br />

some of his operators are better at running,<br />

while others excel at S&P. He also<br />

matches operating stints according to<br />

operator interest.<br />

A common practice at multi-op stations<br />

is to have band specialists. Each operator<br />

is an expert at propagation, operating<br />

practices and activity on their particular<br />

band of interest.<br />

Jules, N2WN, used to pick classes for<br />

other reasons, such as improving his 80<br />

meter DXCC count. Now he often picks<br />

categories where other bands can help<br />

make up for what he considers his big<br />

weakness — not having a great 40 meter<br />

antenna. Jules operates low power and<br />

QRP categories, which match his budget<br />

and interests.<br />

N2WN tries to operate in as many<br />

contests as possible, and he believes<br />

state QSO parties offer a great training<br />

ground.<br />

Now that we are lacking sunspots,<br />

W7WHY prefers contests where everyone<br />

works everyone else as opposed to only<br />

working DX. Right now he is operating<br />

mostly domestic events.<br />

N4ZR feels his strengths lie in knowing<br />

his weaknesses and being realistic about<br />

his competitiveness. Pete concentrates<br />

on operating contests that he enjoys and<br />

improving upon his best efforts. He notes<br />

that given current sunspot activity there is<br />

not much chance of beating his scores in<br />

the 2000 to 2002 contest seasons. Pete<br />

says the biggest improvement would be<br />

to be 40 years old again, but he fi gures<br />

he’ll have to settle for a solar maximum to<br />

beat his previous bests.<br />

Health problems prevent WB4ROA from<br />

operating the full contest period. To compensate<br />

Harold tries to operate at times<br />

when he can make the most contacts. He


mostly runs stations at these times and<br />

rarely S&Ps. Harold says it requires a lot<br />

of planning to do this effectively. He spends<br />

a lot of time with propagation programs<br />

and outlines when and where he will be<br />

operating. Breaks and sleep periods are<br />

scheduled around times when propagation<br />

does not favor him.<br />

VE3WDM lives in a townhouse with<br />

antenna restrictions. He has a High Sierra<br />

Sidekick antenna that he sets up only for<br />

contests. Mike likes this antenna because<br />

it works 80 through 10 meters. On the<br />

other hand, he finds it difficult to stay<br />

motivated given the low QSO rates he’s<br />

able to maintain with his modest antenna.<br />

He’s working to improve his listening skills,<br />

however, and he plans to move to SO2R.<br />

AA4NU considers knowledge of propagation<br />

and current band conditions to be<br />

one of his strengths. Billy feels it is critical<br />

to getting every possible multiplier. He<br />

does have to watch himself, however, lest<br />

he get into a DXing mode. Billy feels he is<br />

strong on the low bands and on an even<br />

plain with the competition on the higher<br />

bands. He tends to pick contests and entry<br />

categories based more on his station’s<br />

strengths than on operator skill.<br />

KE1FO has modest antennas. To<br />

compensate, Al makes a bigger effort to<br />

stay in the chair longer. He also feels his<br />

knowledge of propagation is a big help.<br />

He has a good sense of when the band is<br />

open enough for him to be successful and<br />

which stations he can work quickly.<br />

K8GU/9 says his weakness is lack of<br />

gain on 20. Ethan concentrates on 40<br />

and 80 and enjoys contests like the ARRL<br />

November Sweepstakes, where you may<br />

only work another station once. He also<br />

uses SO2R and practices a lot.<br />

K2DRH is a VHF contester. Bob has<br />

a number of problems that HF operators<br />

don’t normally have to worry about.<br />

First, he runs eight VHF/UHF bands. Bob<br />

considers one of his station weaknesses<br />

to be a lack of automation. Tuning, band<br />

changes and antenna pointing are all done<br />

manually. To compensate Bob feels he<br />

needs to know his station layout very well<br />

to operate it effi ciently.<br />

Antenna pointing on VHF/UHF has<br />

to very accurate because of the narrow<br />

beamwidths common with gain antennas<br />

on those bands. Bob notes that HF<br />

operators who believe they have a narrow<br />

beamwidth with their 5 element Yagis have<br />

no idea of how sharp the pattern is with<br />

122 elements on 3456 MHz.<br />

Bob considers his CW skill lacking for<br />

HF contesting but adequate for VHF/UHF<br />

operation. In VHF/UHF contesting CW<br />

typically only comes into play for working<br />

very weak signals, and you have to go<br />

slowly for that. He notes the slow speeds<br />

used by CW EME operators.<br />

That wraps up this installment of CTT&T.<br />

Records<br />

While not yet offi cial, W5PR is claiming<br />

more than 1700 QSOs in 278 grids in the<br />

ARRL June 2008 VHF QSO Party. Prior to<br />

this, Bob, K2DRH, had posted the all-time<br />

highest 6 meter contest total in any domestic<br />

VHF event. He did this in the 2006 CQ<br />

World Wide VHF Contest with a 6 meter<br />

line score of 1421 QSOs and 288 Grids.<br />

Bob’s total score that year was 700,701<br />

including an additional 260 QSOs and 73<br />

grids on 2 meters. Both 2006 and 2008<br />

were outstanding years for E S .<br />

According to a thread on the VHF Contest<br />

Refl ector, some contest ops believe<br />

the June VHF Party would be improved if<br />

it did not include 6 meters. Now, before<br />

you throw down this issue of NCJ in anger,<br />

there is a reason why some feel this way.<br />

In a June VHF QSO Party like this year’s<br />

with massive E s openings on 6 meters,<br />

most contestants — and particularly casual<br />

entrants — stay on 6. Often 2 meters<br />

and down are neglected. Operators who<br />

prefer UHF or microwave fi nd fewer stations<br />

to work. Thus — the reasoning goes<br />

— if the contest did not include 50 MHz,<br />

then contestants would have to operate<br />

on the higher bands where, presumably,<br />

there would be more activity.<br />

Personally I have some issues with this.<br />

Six meters is a VHF band and has every<br />

“right” to be included in a VHF-oriented<br />

operating event. If 6 meters were to be<br />

excluded from the permissible band lineup,<br />

June VHF contest participation — and log<br />

submissions — would plummet. Activity<br />

in areas away from the Northeast US<br />

and California would decrease. There is<br />

relatively little activity on the UHF or microwaves<br />

from the Rocky Mountain States<br />

or the Great Plains in comparison to what<br />

occurs on 50 MHz. While stations in those<br />

areas did work 2 meter E s , this was the<br />

rare exception.<br />

The June VHF QSO Party is the only<br />

ARRL VHF operating event with a reasonable<br />

probability of E s on 50 MHz. The<br />

<strong>Sep</strong>tember and January VHF contests are<br />

de facto 2 meter, UHF and microwave contests.<br />

E s on 6 meters sometimes occurs in<br />

<strong>Sep</strong>tember and January, but it’s rare. The<br />

multi-op stations operate all bands — 6<br />

meters through the microwaves. They even<br />

do so during big 6 meter E-skip openings.<br />

The current scoring system favors UHF<br />

and microwave contacts, however. To do<br />

well, top contestants must operate on as<br />

many bands as possible. Some years,<br />

34 November/December 2008 NCJ<br />

such as 2008, have seen good tropo and<br />

aurora conditions that favored the higher<br />

bands. So, I recommend leaving 6 meters<br />

in the June VHF QSO Party.<br />

DXpedition Lessons for VHF<br />

Contesters<br />

Several dedicated 6-meter-only DXpeditions<br />

took place in late June and early July.<br />

These included TO5E from St Barthelemy,<br />

CYØX from Sable Island and 5JØM from<br />

San Andres. TO5E made nearly 1800<br />

QSOs on 6 meters, while CYØX logged<br />

nearly 4000 contacts, possibly setting an<br />

all-time record for DXpedition QSOs on<br />

6 meters.<br />

These stations have some characteristics<br />

in common that VHF contesters may<br />

fi nd applicable. In addition to having good<br />

locations, they ran high power into large<br />

Yagi antennas. When operating, team<br />

members would call CQ consistently on a<br />

particular frequency, often using CW. The<br />

Jon K. Jones, NØJK<br />

operators stayed in the chair and kept at it,<br />

whether or not they had apparent propagation.<br />

By doing so they caught nearly every<br />

possible opening. They heard well, and<br />

modest little pistol stations were able to<br />

work them. CYØX heard my indoor dipole<br />

from EM28 on 6 meters July 8 (thanks,<br />

guys!). They do not give up.<br />

CYØX’s stay on Sable Island was extended<br />

due to fog that kept the charter<br />

plane from picking the team up. They continued<br />

to operate on 6 with 100 W into a 5<br />

element Yagi. By doing this, CYØX caught<br />

several big coast-to-coast E s openings<br />

across the US and gave many ops a new<br />

country on 6.<br />

The lessons? Build as good a station as<br />

you are able with the biggest and highest<br />

antenna you can put up. During the contest,<br />

call CQ often and stay in the chair.<br />

Listen carefully for weaker signals and<br />

don’t give up. Persistence is key!


Contesting 101<br />

Welcome back to Contesting 101. Fall<br />

has arrived, and I’m working on making<br />

antenna repairs and other station improvements.<br />

I hope your plans are proceeding<br />

on schedule.<br />

Competition: Winning, Losing and<br />

Playing the Game<br />

Many operators who enter the game of<br />

contesting do so in a very casual fashion.<br />

Our fi rst few forays into contesting might<br />

only involve a few hours of operation<br />

sandwiched between chores, work and<br />

family obligations. Little attention is paid<br />

to overall score; the operation is simply<br />

for the sheer fun of making contacts. Such<br />

casual contest operation is the meat and<br />

potatoes of contesting, however. Without<br />

all of the casual operators on the air, contesters<br />

would run out of people to work in<br />

a hurry. The simple joy of, “Can you hear<br />

me now? Yes I can!” lures us in, and the<br />

outside world with all of its responsibilities<br />

disappears while we’re on the air.<br />

After participating in a few contests,<br />

some operators may discover the joy of<br />

competition. It usually starts off subtly. You<br />

might fi nd that you placed higher than the<br />

operator across town with a better station.<br />

Maybe you received a certifi cate for fi rst<br />

place in your ARRL Section or Division<br />

or in your state. Perhaps a concentrated<br />

effort in a state QSO party resulted in a<br />

plaque or other handsome award. After<br />

a few such achievements, that little light<br />

bulb illuminates to suggest, “Hey, I’m not<br />

too bad at this, and it’s fun to boot!” Some<br />

contesters might discover a fi ercely competitive<br />

streak within themselves that they<br />

didn’t even know existed. Competition is<br />

a peculiar phenomenon. What else could<br />

drive a person to sit in front of a radio for<br />

hours on end, sometimes to the point of<br />

utter exhaustion?<br />

Contesting is ultimately a competitive<br />

game; therefore it brings out all of the<br />

uniquely human behaviors associated with<br />

competition. Some of these behaviors are<br />

exemplary. Some are, well, not so exemplary.<br />

The recent Olympics documented<br />

examples of true championship behavior<br />

and a few bozos as well. Ultimately<br />

operators must decide for themselves<br />

what matters most. Winning a contest<br />

requires a lot of effort, and winners are<br />

to be respected for their dedication and<br />

skill. Winning a major contest is not the<br />

only way to gain the respect of your fellow<br />

operators, however.<br />

The mountain of contesting achievement<br />

is high indeed. As with some other skilloriented<br />

human endeavors, there’s no top<br />

to the mountain, only views from different<br />

heights. When you see the same operators<br />

placing in the Top 10 in the same contests<br />

year after year, that achievement typically<br />

represents decades of contesting effort,<br />

and dozens — if not hundreds — of forgettable<br />

losses throughout their contesting<br />

careers, leading up to that point.<br />

Is Contesting Fair?<br />

Is Amateur Radio contesting fair? In the<br />

end it depends on how you look at it. From<br />

one perspective, it seems that only the<br />

largest stations in the best locations with<br />

the greatest operators have a chance of<br />

winning. While it may appear that little pistols<br />

have no chance, that attitude makes<br />

little sense if you think about it. The big<br />

stations and top operators usually took a<br />

long time and a lot of work to get there, and<br />

it should be very diffi cult to compete with<br />

them. While it’s true that the bar seems to<br />

rise higher and higher every year, history<br />

has shown that operator skill remains the<br />

most important factor in the equation. Big<br />

stations could not win a single contest<br />

without great operators at the helm.<br />

The bad news here is that there really<br />

is no level playing fi eld. The good news is<br />

that those willing to maximize their advantages<br />

and skills can choose to compete at<br />

whatever level they want.<br />

One of the bigger challenges facing the<br />

new competitor is understanding the playing<br />

fi eld. Many new ops get discouraged<br />

before they’ve had a chance to appreciate<br />

how the folks at the top typically climbed<br />

and scratched their way up through many<br />

years of effort. I believe it was N5KO who<br />

said (and I’m paraphrasing), “New contesters<br />

can’t understand or appreciate what<br />

the masters are doing or why.”<br />

New contesters don’t know about the<br />

countless forgettable losing efforts that<br />

preceded the big wins. The new operator<br />

doesn’t understand the amount of time<br />

and practice involved perfecting SO2R<br />

techniques or copying CW accurately<br />

at 40 to 50 WPM. I personally became<br />

very disillusioned with contesting several<br />

years ago, primarily owing to my failure to<br />

understand the playing fi eld. It took me a<br />

while to realize that I immensely enjoyed<br />

the operating and competing, regardless<br />

of the outcome.<br />

I have learned to choose my battles<br />

carefully and now have a better understanding<br />

of what’s possible from my station.<br />

As a result, I’m a lot less frustrated<br />

and less disappointed. I’ve even found a<br />

contest or two that I can win from home.<br />

I’ve traveled for contest DXpeditions and<br />

tasted the thrill of world-class competing<br />

as a team. Now I’m hooked for life on<br />

Kirk Pickering, K4RO<br />

contesting, but it took some real effort and<br />

deeper understanding of the playing fi eld<br />

to get over the hump of feeling like cannon<br />

fodder for the big guns.<br />

Location, Location Location!<br />

It’s helpful to understand the impact<br />

that geographical location can have on<br />

a given contest operation. From the US<br />

for example, the East Coast enjoys better<br />

propagation to Europe and thus has a<br />

considerable advantage in DX contests<br />

over the rest of the country. The high bands<br />

open earlier and longer to Europe, and the<br />

low-band paths are shorter, mostly over<br />

salt water. On ARRL November Sweepstakes<br />

weekends, the place to be is often<br />

somewhere between Louisiana and New<br />

Mexico — not the greatest locations for<br />

DX contesting.<br />

My point is that different regions experience<br />

different propagation, and not all<br />

locations are created equal. There is a<br />

reason that DX contest world titles often<br />

are won from North Africa or by stations<br />

operating from “3-point” countries in the<br />

Caribbean or on the equator. These areas<br />

offer terrifi c propagation paths to the major<br />

contesting population centers. That’s<br />

why top operators go to great lengths to<br />

build stations and to compete from such<br />

areas.<br />

You’ve Got to Play to Win<br />

An interesting aspect of contest operating<br />

is that newcomers essentially compete<br />

on the same playground as the Olympiclevel<br />

operators. So what’s a beginning<br />

competitor to do? The most important<br />

thing a new operator can do is operate<br />

a lot of contests and submit a log. One<br />

way to earn a few wall decorations for the<br />

shack is to choose a contest or category<br />

that requires less hardware than a major<br />

DX contest might. Some state QSO parties<br />

offer great competition without the need<br />

for a mega-station in an exotic location.<br />

The big guns usually prefer to slug it out<br />

in the single-operator/high-power category<br />

of the major contests. SOHP is generally<br />

agreed to be the ultimate operator proving<br />

ground, so we should expect very serious<br />

competition within that category. The lowpower,<br />

QRP and single-band categories<br />

offer great competition as well, with a little<br />

more chance for a good operator at an<br />

effective station to succeed.<br />

Study the results of previous years’<br />

contests, and see if there’s a category that<br />

might be within reach. Operate the contest<br />

fulltime or as nearly as possible, and send<br />

in your log. I’ve seen operators win some<br />

contest categories with fewer than 100<br />

NCJ November/December 2008 35


QSOs. It always pays to send in a log, no<br />

matter what size the effort.<br />

Operating in the mobile, QRP or rover<br />

categories also offers a chance to compete<br />

and be recognized. The National Contest<br />

Journal North American QSO Party and<br />

Sprint events offer great competition that<br />

tends to emphasize operator prowess over<br />

station capability.<br />

An excellent place to start competing is<br />

right in your own area. Study the contest<br />

results and identify the operators who do<br />

well in your area. Compare your scores<br />

with other similarly equipped stations in<br />

your part of the world. If they did better<br />

than you, try to fi nd out why. Did they<br />

operate more hours? Perhaps they chose<br />

different times to be on the air than you<br />

did. Maybe their station is more effective<br />

on one or more bands, or they have better<br />

receiving antennas.<br />

Joining a contesting club can be very<br />

helpful when trying to measure your success.<br />

Seasoned operators from your area<br />

can enlighten you regarding local propagation<br />

patterns. Old timers can help you to<br />

understand the possibilities and help you<br />

to form reasonable expectations. The advent<br />

of more regional reporting has helped<br />

a lot toward recognizing great efforts from<br />

less-advantaged areas.<br />

Some contests also offer rookie categories<br />

or categories for stations with limited<br />

antennas, such as the CQ WPX contests’<br />

“Tri-Bander and Single-Wire” category.<br />

Finally, don’t forget the multi-operator categories.<br />

Competing as part of a multi-op<br />

team is a great way to experience the thrill<br />

of competition and learn some valuable<br />

skills at the same time.<br />

Is Competing Still Fun?<br />

For many of us, throwing everything we<br />

have at something like a radio contest is<br />

beyond fun. It’s a full-blown escape. It’s<br />

blood-pumping, eye-bugging exhilaration<br />

and an exhausting rush that lasts from the<br />

starting bell to the fi nish. While there are<br />

surely tough times of grinding it out in any<br />

full-time effort, operating an entire contest<br />

can be a very gratifying experience. Competition<br />

can be very fun, indeed.<br />

It Really Only Matters to You<br />

Winning is great and is certainly the goal<br />

of most top competitors. Something even<br />

more valuable than winning, however, is<br />

earning the respect of other contesters.<br />

There are ways to gain other contesters’<br />

respect besides winning contests. Of prime<br />

importance is how we handle ourselves on<br />

the air. Effi cient and accurate operating technique<br />

is the best way to earn the respect of<br />

top contesters. I personally respect the operators<br />

with very low error rates, regardless<br />

of their scores. They are the ones I would<br />

want handling my emergency traffi c.<br />

Ultimately it comes down to finding<br />

36 November/December 2008 NCJ<br />

satisfaction in the pursuit itself, regardless<br />

of score. We get out of this game exactly<br />

what we put into it. I’ll close this installment<br />

with some thoughts from two operators<br />

who have seen the view from the top more<br />

than once. N6TJ writes:<br />

“At the end of the day, only you will rejoice<br />

if you met any of your goals. As my<br />

dear friend Ville, OH2MM, opined to me<br />

when we were together in Brazil at PT5A<br />

[several] years ago, ‘Jim, only you will remember<br />

your number ones. Realize that,<br />

have fun and only take yourself seriously.’<br />

Great thoughts to absorb from one of our<br />

forever-best operators.”<br />

Contesting on a Budget<br />

That Very First 3 dB<br />

What will it take to get that next dB? Will it<br />

be cost effective? Will it make things better<br />

or worse? I weigh my wanderlust and need<br />

to take an occasional DXpedition, saving for<br />

retirement, working longer or investing more<br />

in a business venture. I’ve been fortunate to<br />

have been able to build a nice medium-gun<br />

station that once was competitive and have<br />

enjoyed contesting immensely over the<br />

years. Yet, I’m still thinking about how I can<br />

improve my station.<br />

At this point, the law of diminishing returns<br />

starts kicking in, and I have constraints. The<br />

towers are pretty much at their limit, and<br />

there’s not much room for additional wires.<br />

Large, long-boom antennas and stacks just<br />

won’t fi t. It would take an awful lot to improve<br />

my signal. I can add more automation and<br />

fl exibility in the shack, but in the end it comes<br />

down to my perennial problem of being loud<br />

to non-populated parts of the world and running<br />

out of signal strength. You just can’t work<br />

Tibet from an average QTH in the Midwest on<br />

80 meters using an inverted V at 70 feet. To<br />

signifi cantly improve the station at my existing<br />

location just isn’t realistic at this time.<br />

For 40 meters I use an inverted V at 70<br />

feet. It’s okay, but I never dominate and can’t<br />

hold a frequency when the band is crowded.<br />

There are a couple of low-cost options I<br />

could try. A low dipole at about 20 feet would<br />

work great as a mid-day high-angle radiator.<br />

I could also try some phased slopers off<br />

the top of the tower to get a bit of directivity.<br />

Either or both options would cost virtually<br />

nothing. I’ve got coax and wire. These<br />

modifi cations would pretty much complete<br />

my medium-gun station.<br />

Let’s consider the operators who dabble<br />

in contesting. We’ve all worked these folks.<br />

Perhaps he or she is from the local club<br />

Figure 1 — K9NN’s nearly invisible<br />

end-fed wire, which runs just below the<br />

eaves of the house.<br />

and stumbled upon your big signal during a<br />

weekend contest. You encouraged this individual<br />

to exchange information and to scan<br />

the bands and work a few more stations.<br />

Perhaps it was the op on 80 meters fi nishing<br />

up a rag chew when sprint started, and you<br />

discovered he or she was in an uncommon<br />

state, so you worked the station, quickly explained<br />

the contest and encouraged the op<br />

to pass out a few more QSOs. This person<br />

is not “in the contest” but is happy to hand<br />

out a few contacts.<br />

Perhaps this operator is in the contest<br />

club or on the club refl ector and has joined<br />

a team and is just looking to contact other<br />

club members. As I’ve started to collect<br />

ideas for this column I noticed that there<br />

are a lot of these folks. They’re typically<br />

using low wires or perhaps a vertical and<br />

a transceiver without an amplifi er. Serious<br />

contesters rely on these operators to build<br />

their scores, however.<br />

If you’re one of these people, let’s look<br />

at your station and see what improvements<br />

you can make to get that fi rst 3 dB of real<br />

improvement — and do it cheaply.<br />

Initially, I would guess that you operate below<br />

the basic entry level for a contester. This<br />

might mean an inverted V plus a tribander<br />

at 45 feet. Perhaps you’re limited to erecting<br />

only some wire antennas or a vertical. You<br />

don’t make too many contacts, and you’re<br />

not loud. You don’t have much luck calling<br />

CQ and occasionally get covered up, necessitating<br />

many repeats. But you hang in there,<br />

call a lot and give out contacts.<br />

In the end, it’s operators like these who<br />

contribute signifi cantly to a club’s score by<br />

consistently working 100 stations or so.<br />

These are the people who can really beef<br />

up a club’s aggregate score, and I’d guess<br />

that they’re always trying to improve upon<br />

their own previous scores.<br />

Let’s keep in mind the constraints an<br />

operator like this might face, however. This<br />

individual may have recently moved, have<br />

children in college, been off the air for a<br />

while or live in a neighborhood governed by<br />

deed covenants, conditions and restrictions<br />

(CC&Rs) that limit or altogether prohibit<br />

outdoor antennas. Identifying some low-cost<br />

improvements can make this operator’s<br />

station more effective and bring more fun<br />

and activity.<br />

An e-mail from Dale Hammer, K9NN,<br />

got me thinking about what cost-effective<br />

changes might result in some improvement.<br />

He writes: “I live in an antenna restricted<br />

neighborhood and have to be very sneaky<br />

with the antennas. My antennas are a 67foot<br />

end-fed wire [see Figure 1] under the<br />

eaves of the fi rst story of the house (8-foot<br />

height) and a Hustler 4BTV vertical [see<br />

Figure 2] hidden between the house (a foot<br />

Ralph Bellas, K9ZO<br />

Figure 2 — A very well-hidden Hustler<br />

4BTV vertical at K9NN.<br />

away) and a tree (a foot away with limbs<br />

trimmed at strategic locations) at the back<br />

corner of the house.”<br />

Dale’s got a good stealth antenna system.<br />

Obviously that bit of wire his neighbors see<br />

under the eaves is for his shortwave listening<br />

pleasure. This is a great initial setup<br />

because Dale recognizes the constraints<br />

of his situation and still has managed to put<br />

together a station that will allow him to get<br />

on 80 through 10 meters. For now at least,<br />

10 meters is largely dead, and it’s pretty hard<br />

to work anyone with a vertical tucked in the<br />

trees. One contest tip, however, is to make<br />

sure you work at least one of the locals to<br />

catch the multiplier. Above all he’ll get some<br />

enjoyment and relaxation!<br />

As Dale gets on the air more often, he’ll<br />

recognize the limitations of his station. He<br />

may not be too effective on 80, but he will<br />

learn to show up early before the band gets<br />

crowded and work the loud stations. Later<br />

he’ll return and try to snag the next layer of<br />

loud ones. At some point perhaps he’ll try<br />

a low inverted V under the eaves to see if it<br />

works as a mid-day high-angle radiator.<br />

I’d recommend he put up a second vertical<br />

to get some directivity and gain, perhaps<br />

using a large fl ag pole in the front yard. It’s<br />

time to plant that second tree as camoufl age<br />

for that next vertical.<br />

Whatever your initial setup, you have to<br />

aim for some antenna system improvements<br />

to reach that basic level where your signal is<br />

loud enough to work both coasts and have<br />

one band where you can do pretty well.<br />

There’s always something more you can try.<br />

Your efforts will reward you with satisfaction<br />

and contribute to your club’s score.<br />

RTTY Contesting<br />

Just two years ago, Don, AA5AU, began<br />

writing this column. While Don was<br />

eager to get started, he was also reluctant<br />

because his available time was mostly<br />

consumed with rebuilding his home and<br />

antennas after the devastation Hurricane<br />

Katrina wrought. Still, he took on the NCJ<br />

task with gusto and has been sharing<br />

his perspective on RTTY contesting ever<br />

since. This sharing is an extension of the<br />

tremendous contribution he’s made to<br />

RTTY contesting through the tutorials<br />

and other resources on the Web sites<br />

(eg, www.rttycontesting.com). As Hurricane<br />

Gustav approached Louisiana in<br />

late August, however, Don and his wife<br />

once again found themselves evacuated.<br />

Needless to say, Don needs to take<br />

some time away from this column as he<br />

assesses the situation with his property<br />

and gets permission to return and deal<br />

with whatever he fi nds. It is my pleasure<br />

to guest op his column for this issue. I’m<br />

sure you’ll join me in hoping that Don will<br />

be back with us soon.<br />

As I write this, the CQ World Wide RTTY<br />

Contest; it will be history by the time this<br />

issue of NCJ reaches subscribers in late<br />

October. As it is for the CW and phone<br />

modes, CQ WW is one of the biggies in<br />

RTTY contesting along with the ARRL<br />

RTTY Round-Up in January and the CQ<br />

WW WPX RTTY in February. Active participation<br />

in these and other RTTY operating<br />

events continues to grow phenomenally<br />

and the trend is expected to continue. Don<br />

described this growth in an earlier column,<br />

attributing part of it to CW and phone<br />

contesters who have added RTTY to their<br />

contesting enjoyment. My own personal<br />

experience has been exactly that.<br />

Beginning with the 20<strong>04</strong> ARRL RTTY<br />

Round-Up, club competition was added.<br />

Our contest club, the Northern California<br />

Contest Club (NCCC), decided to pursue<br />

this as a goal. Problem was that few club<br />

members operated RTTY, let alone contested<br />

seriously in that mode. The club has<br />

a number of top-tier CW and phone contesters,<br />

however. In late 2003, a core group<br />

of RTTY ops — N6DE, AC6JT, K6UFO<br />

and W6ZZZ — put on a meeting program<br />

to explain the mode and to inspire other<br />

club members to get on for the Round-Up.<br />

Like several others, I had never operated<br />

RTTY and had an unfounded cynical view<br />

of the mode. I remarked that since the<br />

RTTY contest software identifi ed valid call<br />

signs and could easily send the exchange<br />

with little or no operator intervention, the<br />

operator could go drink beer. With a bit of<br />

a frown, the RTTYers informed me that<br />

there was more to it than that, and most<br />

people really enjoy it once they actually try<br />

it. “Okay,” I said, “for the good of NCCC, I’ll<br />

get on RTTY Round-Up.”<br />

As it turned out, I won the Pacifi c Division<br />

SOHP plaque that year and, as the<br />

club’s RTTY contingent predicted, I had a<br />

blast. I was hooked, despite the fact that<br />

CW contesting is still my favorite. Moreover,<br />

thanks to the additional members<br />

recruited (kicking and screaming, mostly!),<br />

the NCCC won the fi rst club competition<br />

gavel in the ARRL RTTY Round-Up. It<br />

also took a couple days for ghosts of<br />

those RTTY tones to dissipate within my<br />

head. I’ve since learned to turn the audio<br />

gain way down during RTTY contests so<br />

they no longer imprint themselves on my<br />

brain.<br />

It wasn’t immediately obvious why I liked<br />

RTTY so much, particularly since I had<br />

the initial negative bias about operators’<br />

not actually decoding the signal in their<br />

heads. For starters, RTTY is like CW in<br />

that you don’t have to speak, so that was<br />

appealing. Next, the differences between<br />

RTTY and CW provided diversity that<br />

increased the interest and satisfaction of<br />

each contest session for both modes. The<br />

biggest advantage for me was utilizing<br />

RTTY contesting to improve my overall<br />

contesting skills. The very aspect that I<br />

cynically belittled — operators not decoding<br />

the signal — turned out to be the<br />

enabling factor for building other areas of<br />

operating skill. Instead of bemoaning that<br />

RTTY is not as challenging because the<br />

brain is not “copying” the code, I soon realized<br />

that this actually liberated my brain<br />

to focus on other things, such as effi cient<br />

searching, pileup management, exception<br />

management (fi lls, slow exchanges, etc),<br />

SO2R and possibly even SO3R.<br />

For example, before I’d operated RTTY,<br />

I found it very diffi cult to realize any advantage<br />

from SO2R during sprints. I was<br />

so consumed with one radio in the Sprint<br />

that I’d never achieved any success with<br />

two. With RTTY, however, I had freed up<br />

brain cycles to apply to the problem of<br />

Ed Muns, WØYK<br />

operating two radios in Sprint without<br />

decreasing my score. Once I developed<br />

some techniques in the RTTY sprints, I<br />

then had the foundation to ease them into<br />

my CW Sprint operating.<br />

I’m now a reformed RTTY contester,<br />

greatly enjoying the mode, coming from<br />

the other extreme of thinking it was<br />

somehow invalid. At Contest University in<br />

Dayton last May I asked the audience how<br />

many still thought RTTY contesting was<br />

silly and were only there because there<br />

was nothing else going on at that hour.<br />

A number of diehard anti-RTTYers raised<br />

their hands, so it’s clear that conversion<br />

will never be 100 percent. Still, I urge all<br />

skeptics out there to look for the silver lining<br />

in this odd contesting mode. You may<br />

surprise yourself and fi nd some appeal. It’s<br />

been really gratifying — though shocking<br />

at fi rst — when presumably non-RTTY<br />

contester call signs such as K5ZD, N6TR,<br />

N2NL, N2IC, K7JA and N6TV show up in<br />

my logs.<br />

On the other side, RTTY contesting<br />

has benefited greatly by experienced<br />

contesters engaging in this mode. Not<br />

only is participation rapidly increasing, but<br />

competitiveness and expertise is growing<br />

as well. Early RTTY contests were more<br />

like relaxed QSO parties with rag chewers<br />

getting together on the air for the weekend.<br />

Exchanges were drawn out with little pressure<br />

on effi ciency or speed. Today’s RTTY<br />

contests have evolved to the same quick<br />

clip found in CW contests. The NA RTTY<br />

Sprint just eliminated the special “legal<br />

dupe” rule for RTTY, wherein participants<br />

could work the same station multiple times<br />

for credit on each band if at least three<br />

QSOs with other stations intervened. The<br />

original purpose of allowing these multiple<br />

dupes, of course, was to provide a decent<br />

rate despite low participation.<br />

This handicap really isn’t needed anymore,<br />

however, as the number of RTTY<br />

Sprint participants is approaching SSB<br />

Sprint numbers. Now the NA Sprint rules<br />

are identical for all three modes.<br />

If you’re still sitting out RTTY contests,<br />

you could be missing out on a lot of fun<br />

as well as the opportunity to improve your<br />

overall contesting expertise and enjoyment.<br />

Give it a spin!<br />

Results: 2008 West Coast Regional<br />

Radio Team Championship<br />

“Start small and build.” — Bill Gates<br />

The first-ever West Coast Regional<br />

Radio Team Championship (WCRRTC)<br />

is now in the record books. The Southern<br />

California Contest Club fi elded a small but<br />

dedicated group of competitors. We hope<br />

you had a chance to work one of the three<br />

W6 1×1 stations during the International<br />

Amateur Radio Union (IARU) HF World<br />

Championship in July. All stations sported<br />

two-operator teams running mixed mode<br />

in the style of the World Radiosport Team<br />

Championship (WRTC) events (the next<br />

WRTC is scheduled for <strong>2010</strong> in Russia).<br />

The results of WCRRTC 2008 have<br />

been tabulated, and — as it happened —<br />

the three teams fi nished in alphabetical<br />

order by call sign:<br />

♦ W6A (N6KI + N6OX) — 288,768<br />

♦ W6B (WA6L + N6ERD) — 276,360<br />

♦ W6C (WN6K + W6NOW) — 149,8<strong>04</strong><br />

Dennis, N6KI, and Bob, N6OX, barely<br />

edged out newcomers John, WA6L, and<br />

Dan, N6ERD, operating from John’s horse<br />

ranch in the hills east of San Diego. Coming<br />

in third was veteran contester Paul,<br />

WN6K, with new papa Juan, W6NOW.<br />

See the box scores for details, which differ<br />

because the three teams did not use the<br />

same logging software.<br />

Ordinarily the race would be too close to<br />

call until the logs were checked. Because<br />

WCRRTC rules differ from IARU rules,<br />

however, the ARRL is unable to provide<br />

a log-checking report. As a result, and per<br />

our rules, we must go by claimed score to<br />

determine the winner.<br />

The fi rst-place team receives a plaque,<br />

while the second and third-place teams<br />

get certifi cates. Awards will be presented<br />

at the 2009 International DX Convention<br />

in Visalia, California.<br />

W6A<br />

W6A deployed an ICOM IC-7800,<br />

ACOM 2000A amp, 4-element MonstIR<br />

SteppIR antenna — modifi ed with one<br />

element for 40, an 80 meter inverted<br />

V coaxial stub dipole and a 160 meter<br />

longwire.<br />

“As the contest weekend approached it<br />

was looking like N6KI might have to forgo<br />

the competition due to other pressing matters<br />

that would keep me from reassembling<br />

the station after Field Day,” Dennis<br />

reported. “I worked into the wee hours Friday<br />

night to get everything back together<br />

and confi gured.” He said two other ham<br />

friends he’d approached about being his<br />

teammate also had to decline at the last<br />

minute due to busy work schedules.<br />

At the eleventh hour, Dennis explained,<br />

consummate world traveler and DXpeditioner<br />

(TX5C and others) Bob Grimmick,<br />

N6OX — just back from Europe where he’d<br />

attended the Ham Radio 2008 gathering<br />

in Friedrichshafen, Germany — happened<br />

to call. Dennis recruited him as his<br />

WCRRTC partner.<br />

“Knowing that Bob was an SSB-only op,<br />

I jumped on 15 CW only to fi nd a few sta-<br />

tions left at midday, and then jumped in the<br />

fray on 20 CW,” Dennis recounted. “Then<br />

at mid-afternoon, Bob started cranking out<br />

Qs on 20 SSB.”<br />

Dennis reported that “some issues”<br />

arose in getting the control box of his<br />

MonstIR SteppIR antenna to retract all but<br />

the driven element so the antenna would<br />

qualify as a single-element antenna on<br />

40 meters.<br />

“Every time I tried to QSY back to 15<br />

and 20 meters, the antenna would not<br />

extend its related elements properly,” he<br />

explained. “So I fi nally gave up.” Only after<br />

fi guring a way to extend only the driven<br />

element on 40 did the pair shift to that<br />

band at 0520 UTC. “We gave up trying to<br />

get back on 20, which, though milked out,<br />

might have yielded a few more Qs and<br />

mults,” he said.<br />

For W6A, 20 and 40 meters turned out<br />

to be the money bands. “We found 80<br />

meters at 0800 to be relatively quiet with<br />

no storms in the area, and we picked up<br />

eight zones and three HQ stations there,”<br />

Dennis recalled. “If there was an opening<br />

on 10 meters Saturday morning we<br />

missed it, and we erred by not putting in<br />

a bit more time on 160. Forty meters was<br />

really hopping the last three or four hours<br />

of the contest, and we had great openings<br />

to JA.”<br />

Dennis said it came as a surprise that<br />

with only slightly more than 1000 Qs the<br />

team found itself in contention for fi rst<br />

place. “It ironically and coincidentally<br />

turned out that all three stations had one<br />

op who only worked SSB and one who<br />

could operate mixed mode, but I suspect<br />

the mixed-mode ops at each station<br />

worked mainly CW, leaving SSB to their<br />

teammates.”<br />

“Bob and I were very happy that we were<br />

able to participate,” he concluded. “Thanks<br />

to John for putting together this new, fun<br />

competition, and we hope it becomes an<br />

annual event during WRTC ‘off years’ for<br />

many years to come.”<br />

“This was the fi rst full 24-hour effort for<br />

both me and Dan,” reported John, WA6L.<br />

“We both learned quite a bit from the<br />

experience.”<br />

“You reach a point in the early morning<br />

where that little part of your brain that decodes<br />

CW goes to sleep,” John continued.<br />

“At one point you are enjoying a modest<br />

NCJ November/December 2008 41


un on 40. The next minute everything<br />

sounds like ‘Mary Had a Little Lamb’<br />

played on the ocarina.”<br />

“Propagation was not too bad. Basically,<br />

20 was open the entire 24 hours to somewhere.<br />

At 0800 we were working the East<br />

Coast on long path and listening to our<br />

echoed signals traveling around the globe<br />

— which seems really cool when you are<br />

sleep deprived. There was a brief opening<br />

on 15 and an even shorter one on 10.<br />

“We lost our 160 meter antenna right<br />

before the start of the contest when someone<br />

let the smoke out of the antenna relay<br />

switch. I don’t think it cost us too much. We<br />

did fi ne on 40, but we really had a hard<br />

time on 80 with the compromise vertical<br />

we were running. That is something we<br />

need to work on for next time.”<br />

John reported that working Europe “was<br />

a stretch” that weekend. “We got some,<br />

but they were hard work.” Fortunately, the<br />

team found favorable propagation to Oceania<br />

and to the Far East and was able to log<br />

a respectable number of fi ve-pointers.<br />

Using a 1×1 call sign carries its own<br />

benefits and challenges, he said, but<br />

it puts all stations on an equal footing<br />

with respect to call sign length. “But the<br />

most comical moment of the contest was<br />

listening to Dan trying to explain a 1×1<br />

call to D4C, who should have been able<br />

to fi gure it out: ‘One, two, three. You have<br />

three, we have three.’ I wish I’d had a tape<br />

recorder.”<br />

“We had two stations networked with<br />

WriteLog, and that was pretty sweet,” he<br />

recounted. “You can set it up so that when<br />

one station is sending, it locks out the<br />

other. There were some limitations and<br />

a couple of minor problems, but it was a<br />

solid confi guration that I<br />

wouldn’t hesitate to use<br />

again.”<br />

“All in all, it was fun and<br />

educational,” John said in<br />

summary. He quipped that<br />

Amateur Radio contests<br />

should not be sponsored<br />

by radio manufacturers<br />

but by purveyors of coffee,<br />

caffeinated soft drinks,<br />

beef jerky and pretzels.<br />

“Wearing Depends does<br />

not improve your score,”<br />

he added.<br />

“We are already making<br />

plans and coming up with<br />

ideas for next year. Thanks<br />

to K6AM and the SCCC for<br />

this great idea!”<br />

created by John, K6AM, someone had to<br />

come in last,” Paul philosophized afterward.<br />

“Band conditions were sporadic.<br />

Although at times we heard loud stations<br />

calling CQ, we just could not be heard<br />

by them, and they were those precious<br />

multipliers.<br />

“Juan and I only used a single radio due<br />

to no equipment here at WN6K to operate<br />

SO2R,” Paul continued. “Although the rules<br />

for our contest-inside-the-contest allowed<br />

that we could switch bands with impunity,<br />

we chose to stay within the 10-minute<br />

rule of the IARU so that we could submit<br />

a ‘regular’ score there.”<br />

According to Paul, he handled all of the<br />

CW operating while Juan dealt with “the<br />

other mode,” with the exception of 40 and<br />

75 meters, where they took turns. He said<br />

the pair had more requests to repeat their<br />

1×1 call sign on SSB than on CW.<br />

“Thanks for the QSOs. We got a minitaste<br />

of what the WRTC might feel like,”<br />

he concluded. “Bottom line: Lots of fun,<br />

but competing at WRTC level is in the F 2<br />

layer as far as our abilities and equipment<br />

limitations go. Do more S&P if you are not<br />

loud is the lesson learned, but then that’s<br />

why we contest — to learn more.”<br />

WCRRTC 2009?<br />

Thanks to all who helped by giving points<br />

to our teams. If there’s enough interest, we<br />

will try it again next year.

Charlie, KI5XP, once again played superstation<br />

W5WMU to victory. Dean, KEØWO,<br />

used NØNI’s fi ne station for a second-place<br />

fi nish. AA3B, AA5AU, and N4ZZ round out<br />

the top fi ve. The team at W6YK (N6CCH,<br />

W6RK and N7MH) continued its domination<br />

of the M/2 category. SWACC (KI5XP,<br />

AA5AU, W7WW, AD6WL and WØHW) easily<br />

captured the team competition.<br />

New state records were established<br />

— K1FWE in New Hampshire, AA3B in<br />

Pennsylvania, K4FX in North Carolina,<br />

KL7RA in Alaska, NX7F in Nevada and<br />

KEØWO in Iowa.<br />

Congratulations to all, not just the top<br />

scorers. Without all of the “other” partici-<br />

pants, those winning scores would not be<br />

possible.<br />

Thanks to Icom America for its exclusive<br />

sponsorship of the NAQP RTTY<br />

handling the log checking and — last but<br />

not least — to each participant.<br />

A picture is worth a thousand words...<br />

With the<br />

TM<br />

ANTENNA MODEL<br />

wire antenna analysis program for Windows® you get true 3D far field patterns that are far<br />

more informative than conventional 2D patterns or wire-frame pseudo-3D patterns.<br />

Now you can have all the advantages of the MININEC code and Sommerfeld-Norton<br />

ground too, down to 0.02 wavelengths above ground. No split load, split source, or equivalent<br />

monotaper element approximations are needed. Enjoy superior graphing and 2D far<br />

field plot comparison capability.<br />

Describe the antenna to the program in an easy-to-use spreadsheet-style format, and then<br />

with one mouse-click the program shows you the antenna pattern, front to back ratio, front<br />

to rear ratio, input impedance, efficiency, SWR, and more.<br />

An optional Symbols window with formula evaluation capability can do your calculations for<br />

you. A Match Wizard designs Gamma, T, or Hairpin matches for Yagi antennas. A Clamp<br />

Wizard calculates the equivalent diameter of Yagi element clamps. Yagi Optimization finds<br />

Yagi dimensions that satisfy performance objectives you specify. Major antenna properties<br />

can be graphed as a function of frequency.<br />

There is no built-in segment limit. Your models can be as large and complicated as your<br />

system permits.<br />

ANTENNA MODEL is only $90. This includes a Web site download and a permanent backup<br />

copy on CD-ROM. Visit our Web site for more information about ANTENNA MODEL.<br />

Searching for peak HF performance?<br />

Introducing the<br />

Elecraft K3 transceiver<br />

No other rig in this price class comes<br />

close to the K3’s performance. Its high<br />

dynamic range, down-conversion<br />

architecture provides roofi ng fi lter<br />

bandwidths as narrow as 200 Hz, while<br />

its 32-bit I.F. DSP handles advanced<br />

fi ltering and noise reduction. The K3<br />

also offers an optional fully independent,<br />

high-performance subreceiver, as well as<br />

innovative new features like variablebandwidth,<br />

DSP-tracking roofi ng fi lters,<br />

and 8-band RX/TX EQ.<br />

Then there’s the K3’s unmatched versatility.<br />

It provides state-of-the-art performance as<br />

a primary home station, yet its size and<br />
