“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 />

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 />
“Most of the time signals were right at<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 />

North American QSO Party SSB event. We<br />
feel that was a great success.<br />
Louisiana Contest Club will provide a<br />
vehicle for members to further develop<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 />
Preamplifi er<br />
An LED power-on indicator can speed<br />
acceptance testing and troubleshooting<br />

Notch fi lter<br />
Chassis-mount F connectors often loosen<br />
up when tightening a cable. Opening the<br />
box to tighten the connector nut and lock<br />
washer takes time and breaks any weatherproof<br />
seals. Board-mounted F connectors<br />
don’t suffer from this shortcoming.<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 />

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 />

24 November/December 2008 NCJ
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 />

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 />

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 />

All-Time 6 meter VHF Contest QSO<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 />
W6B<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 />

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 />
weight make it ideal for DXpeditions,<br />
RV operation, and Field Day. You can take<br />
it with you!<br />
