NEW HF OPERATORS - THINGS TO DO

You'll enjoy trying for the Clean Sweep of all 80 sections in
Sweepstakes. It's how a lot of today's contesters got their starts and
you'll see why once you start filling your log. Watch for pileups on
stations from VY1/VE8 and VO1, but don't forget that every section
counts just the same! If asked for your "precedence" - respond with
your category abbreviation. Your "check" is the last two digits of the
year you were first licensed. All this is explained in the Sweepstakes
articles on the ARRL Contest Branch <http://arrl.org/contests> Web
site.

BULLETINS

Remember that CW Sweepstakes logs are now due 15 days after the contest
- that's November 24! QST's printed Contest Corral page has the old
dates (your editor is responsible for that). If you know anyone needing
a little help submitting their Cabrillo-formatted log or converting a
paper log, here's your opportunity for a good deed and a little contest
Elmering.

BUSTED QSOS

A golden issue last time!

==> NEWS, PRESS RELEASES, AND GENERAL INTEREST

Congratulations to the WRTC-2010 teams! The complete list of team
leaders and teammates <http://wrtc2010.ru> has been published by the
WRTC-2010 Committee. I see a good mix of familiar and new calls. If
you're interested in what propagation will be like from Moscow in July
of 2010, the SRR has published all logs
<http://www.srr.ru/CONTEST/ozchr_09_och_logs.php> for the 2009 Russian
Radiosport Team Championship. (Thanks, Harry RA3AUU)

John VE8EV was a welcome QSO in a lot of Sweepstaker's logs this
past weekend. You can enjoy his writings about CW Sweepstakes and other
contests on his blog <http://ve8ev.blogspot.com/>. (Thanks, Tree N6TR)

The Southeastern VHF Society <http://www.svhfs.org/> is calling for the
submission of papers and presentations for the upcoming 14th Annual
Southeastern VHF Society Conference to be held at Morehead State
University in Morehead, KY on April 23rd and 24th, 2010. Papers and
presentations are solicited on both the technical and operational
aspects of VHF, UHF and Microwave weak signal operating. The deadline
for the submission of papers and presentations is February 5, 2010.
(Thanks, Robin K4IDC)

Readers of Popular Mechanics may have missed it in October 2009's "The
Self-Reliance Issue", but the article "Ready For Anything
<http://www.popularmechanics.com/science/worst_case_scenarios/4330416.html>",
by Glenn Harlan Reynolds mentions that "One underappreciated is the
amateur radio community. Acquire a ham radio license...and you can
become a major resource if a disaster strikes. It's fun, too." Another
well-written article on the technical attractions of ham radio appeared
in the Computerworld online article "Want to bone up on wireless tech?
Try ham radio <http://tinyurl.com/yz49ntg>" by John W6JE. Psssst - I
think this ham radio thing may be catching on again!

David K1TTT contributed this item appropriate for a Veteran's Day
<http://en.wikipedia.org/wiki/Veterans_Day> issue. "USAA
<http://www.usaa.com/> is a coop for US Military and their families
that provides insurance, banking, investment services, etc. Until now
you had to join while you were on active or reserve duty, but now they
have opened up membership to all who have honorably served in the US
Military." David has been a member for 30 years including home owner's
insurance that has covered damage to towers, antennas, and radios.

Contest University (CTU) UK
<http://www.icomuk.co.uk/categoryRender.asp?categoryID=3508&cCID=7775>
Director Mark M0DXR reports that the event is growing - attracting 245
students as part of this year's RSGB Convention at Wyboston Lakes in
Bedfordshire on October 10th. This is almost double last year's
attendance! Classes were taught by 14 of the UK's top contest operators
and Tim K3LR via video link from the USA. Mark also extends his thanks
to CTU UK sponsor Icom UK, helping CTU
<http://www.contestuniversity.com/> continue to grow on a global scale,
all of the professors, and his wife Gemma 2E0WPX for managing the
certificates.

The The success of the K3 transceiver and other radio products has
propelled Elecraft into a new building!
<http://www.elecraft.com/images/elecraft_new.jpg> Was SETI the first
organized attempt to detect communications from extraterrestrial
civilizations? Hardly! How about a 1924 exercise
<http://www.examiner.com/x-21670-Houston-Space-News-Examiner%7Ey2009m11d8-US-Navy-Ordered-to-Listen-for-Martian-Radio-Broadcasts-in-1924>?
(Thanks, Brent W5WW)

A dictionary isn't a lot of use for spelling assistance! If you're
confronted with having heard a technical term whose spelling escapes
you (remember the first time you heard "quartz crystal"?), try Gabby's
Wordspeller phonetic dictionary <http://www.gabbyswordspeller.com/>
from DMFrank Publishing. It can also help young students or someone
learning English.

Web Site of the Week - We're about to get another pair of eyes on the
Sun as NASA launches the Extreme Ultraviolet (EUV)
<http://www.physorg.com/news175970429.html> mission in the coming
months. The additional data may shed some light of the visible kind on
the workings of the solar dynamo on which HF propagation depends.

WORD TO THE WISE

Regional - Every contest has a favored region depending on propagation
or geography or both. If you operate from such a QTH, you are far more
likely to receive notice in the results than when operating elsewhere.
If you would like to see more coverage of your non-favored region,
consider volunteering to write a short review of the contest from your
perspective. With many result writeups expanding on-line, their authors
would probably be happy to include your contribution!

==> SIGHTS AND SOUNDS

Jim K7WA was active during the CW Sweepstakes while portable from the
Lamar Buffalo Ranch in Yellowstone National Park. You can read about
his adventures <http://www.lamarbuffaloranch.blogspot.com/> as a
winter-months volunteer and what happened when his antenna farm met the
fabled bison!

Here's a video of the antennas
<http://www.youtube.com/watch?v=HA8Th4uET7k> on Midway Island taken by
Joe AA4NN during the recent K4M expedition. Additional photos are
available on the expedition's Web site <http://www.midway2009.com/>,
too. (Thanks, Lynn W4NL)

Thor TF4M sends his greetings from the Arctic and a Web site describing
his new Top Band transmitting antenna, known as "The King
<http://tf4m.com/archives/tag/the-king>". As Thor says, "The King is
ready for action - action speaks louder than words."

In case you were wondering about the SOS distress signal
<http://en.wikipedia.org/wiki/SOS> - perhaps after too many hours in
the operating chair this weekend - the Wikipedia entry thereupon comes
with its own sound bite, too. Good reading for non-hams, too! Note that
Firefox users may hear an extra couple of dits after the first playback
or two - maybe "iSOS" was just a bit ahead of its time. (Thanks, Ramon
XE1KK)

==> RESULTS AND RECORDS

The last SS CW QSO was made less than two days ago, and we've already
received over 800 logs! That is outstanding! Participation was high,
the bands were in great shape, and the low bands were quiet. I haven't
had any reports of frequency fights or intentional QRM from either
contesters or non-contesters. This sounds like a very gentlemanly
affair. Many, many thanks to the operators who activated he rare
sections; being QRV from one of the Rare Ones can start to feel like an
obligation after a while. Know that your efforts are appreciated by all
that managed a Clean Sweep. Don't forget to get those SS CW logs in to
HQ by 0300Z November 24th. Will the great conditions roll over to SSB
Sweepstakes? Let's certainly hope so! Don't forget to be mindful of the
non-contesters that will be utilizing the phone bands on the weekend of
the 21st. Go the extra mile to be polite and accommodating, and be sure
to ask if that frequency is in use before firing up the voice keyer. CU
in a couple weeks! (Thanks, ARRL Contest Branch Manager Sean KX9X)

Dink N7WA reports that the CW Sweepstakes Soapbox collection
<http://www.eskimo.com/%7Emwdink/3830/> is growing! These are comments
harvested from the score reports submitted via the 3830 reflector
<http://www.hornucopia.com/3830score/>. Bob K0RC reminds us that his
spreadsheet-based Sweepstakes log analyzer <http://tinyurl.com/pkygbe>
is also available for post-pileup perusals.

I know - it's not a contest - but the Field Day results
<http://www.arrl.org/contests/results> are online, too!

Preliminary results for the NA RTTY Sprint
<http://www.ncjweb.com/sprintrttyprelim.php> held on 11 October 2009
are on the National Contest Journal's Web site. Full results will be in
the Jan/Feb issue. Log checking reports (LCRs) can be requested with an
email to rttysp...@ncjweb.com. (Thanks, NA RTTY Sprint Manager, Ed
W0YK)

If you entered CQ WW Phone in the new Xtreme category, the instructions
in CQ and on the CQ Web site are in error for constructing your
Cabrillo log. The log should contain this line in the header area:
CATEGORY-OVERLAY: XTREME. A category of "SINGLE-OPERATOR XTREME" will
be rejected as invalid. (Thanks, Doug K1DG)

Certificates for the 2009 CQ 160 Contest <http://cq160.com/index.htm>
were all mailed recently, thanks to the help from Barry W5GN. Trophies
are soon to follow. Results will appear in the December 2009 issue of
CQ magazine and log checking reports will be available by request from
dire...@cq160.com. (Thanks, CQ 160 Meter Contest Director, Andy N2NT)

OPERATING TIP

Start early - not the contest, but your preparation for the contest.
For example, Friday afternoon is a bad time to start downloading a new
version of software or to discover that you're missing a filter or
cable or connector!

==> TECHNICAL TOPICS AND INFORMATION

Tropospheric propagation ("tropo" for short) is an important part of
VHF+ contesting, but given its weather-related nature, can it be
predicted? Jim W4KXY uses the Hepburn tropo prediction maps
<http://www.dxinfocentre.com/tropo.html> to determine when and where to
look for tropo openings. The maps are derived from world-wide weather
data and are updated daily.

To help you with that tower-building design, here are some links to
Online Metal's information on mast materials. Yield strength
<http://www.onlinemetals.com/steelguide.cfm> is a good place to start
followed by a visit to the weight calculator
<http://www.onlinemetals.com/calculator.cfm>. (Thanks, Craig Ervin)

When building that tower, we try to minimize the weight of the tool
bucket but don't want to risk having to climb all the way down again.
The result is that we usually haul more tools than we need. How about
an eight-in-one socket wrench? The November 2009 issue of Popular
Mechanics Home Journal column
<http://www.popularmechanics.com/home_journal/tools/4335362.html>
reviewed the Craftsman Dog Bone and Black & Decker ReadyWrench in their
"wish list" column. The combination wrenches feature two sets of four
rotating sockets on a single handle.

More interesting tools for radio and antenna work are available from
Davis RF <http://www.davisrf.com/tools.php>. They have a new page on
their Web site featuring cable preparation tools to make those feed
line and connector installation chores a lot easier.

Doug K1DG was confronted with an aerial challenge - Phillystran truss
cables on a large beam had slipped out of cable clamps on the boom. Was
he going to have to lower or rotate the antenna to reattach the truss?
His solution was to "...attach the loose end of the Phillystran with
new cable clamps and thimble to a stainless-steel snap hook similar to
a carabiner. I taped the snap hook open with a single turn of tape,
connected a long piece of strong string firmly to the tape, and
threaded the string through the eyelets of a fishing pole. I
disconnected the Phillystran at the mast end to give me some slack,
then went "fishing" for the eye bolt on the boom. I had to extend the
fishing pole with a long wooden pole to reach the eyebolt." When Doug
"had a bite" with the hook in the eye bolt, yanking the string pulled
off the tape so the snap hook could close, capturing the cable in its
original position!

We've all encountered Ground Fault Circuit Interruptors (GFCI), but how
about Arc Fault Circuit Interruptors (AFCI)? Paul W9AC posted a link to
an explanation of these two protective devices
<http://www.sccelectrical.com/gfciafciinfo.htm>.

Analog Device's email newsletter Analog Dialogue contains some great
tutorials and overviews. This past issue contained the second part of
"Phase Response in Active Filters
<http://www.analog.com/library/analogDialogue/cd/vol41n4.pdf#page=3>".
Phase response is important to understand, especially in applications
like narrow CW filters. If you like lifting the hood to see what makes
circuits go, this is a good newsletter to receive.

Skip KH6TY has published a simple design for interfacing sound cards
and radios <http://home.comcast.net/%7Ekh6ty/interface/>. PTT is
derived from the output audio, eliminating one control signal path.
This might be handy for getting on the air for a digital mode contest.

Instead of attaching Beverage antenna wires directly to trees, Steve
HA0DU has an alternative that keeps the wires straight and flexible. "I
put pieces of [bailing twine] between pairs of trees along the path and
the Beverage wire is attached to these. This results in less
zig-zagging and larger distances from trees. The ropes are a little
loose, so even if the trees are moving in the wind, the ropes are not
broken."

Technical Web Site of the Week - The shape of a rhombic antenna forms
the outline of radio society logos from our own ARRL and those around
the world. With its almost mythical reputation, here's one of the
original technical (and equation-laden) papers on the rhombic
<http://puhep1.princeton.edu/%7Emcdonald/examples/EM/foster_pire_25_1327_37.pdf>
and how it does what it does. (Thanks, Larry N7DF)

==> CONVERSATION

Check It Out!

Is it just my imagination or did this year's Sweepstakes have more
checks (the last two digits of the year first licensed) beginning with
9 or 0? And this was the CW weekend - the phone weekend ought to bring
out even more new HF operators! The word may be getting out that
radiosport is a lot of fun! Not that one has to become a total devotee,
but a casual game now and then is a great way to get a little radio
exercise.

Most contests are open-ended, meaning that it's very difficult to work
every participant or every multiplier. Sweepstakes is an exception with
its coveted "Clean Sweep" of all 80 sections. Ed VE4EAR not only made a
lot of "sweeps" possible, but has captured the excitement of chasing
one very well with this 3830 post
<http://lists.contesting.com/archives/html/3830/2009-11/msg00358.html>:
"The magical thing that separates Sweepstakes from all other contests
is the personal emotion that comes with it. This is truly one contest
where big gun or little pistol, everyone is searching for the elusive
"SWEEP". You may not win a section but the sweep is a goal within
reach. Even though this is CW, you can hear the emotion in the other
party when you give them a sweep. Congratulations to all that achieved
their goals!"

There is a sizeable group of operators gunning for 80-80; 80 sections
in 80 QSOs. Some go for Worked All States or Worked All VE. I know I
filled out a considerable chunk of my 5BWAS-QRP QSOs during Sweepstakes
by working the Big Guns with ears to match. Each Sweepstakes mug,
broom, medal, and pin has a special place in my ham radio history.

That Clean Sweep is something even non-hams can understand. How many of
us have had a visitor stop in at the shack door and ask if we've
"gotten our sweep, yet?" It flavors the whole contest with scores
reported afterwards as "XXX QSOs and a sweep" or "YYY contacts and
missed [fill in one of the usual suspects here]". Part of the name and
part of the competition, it's all about the sweep.

The flip side of a sweep is helping others make their sweep from a
needed section. Some sections are so rare that operators from those
locations might have serious difficulty making a sweep of their own,
even as they are handing out the final section to others left and
right. I got a taste of that buzz by operating from Wyoming as WY7SS
last weekend (with K7JA and others), hearing many "TKS WY" as a QSO was
completed. It feels good!

Let operators from those rare sections know that you appreciate their
efforts. For many years, VY1JA was our only hope from his Yukon station
and the pileups were legendary. Today, stations like VE8EV, VY1EI, and
VE8NWT are filling the logs. VO1MP gets on to run the pileups on NL
from the other side of the continent. And there are many others with
the world beating a path to their receiver front ends.

All on account of that fabulous sweep! If there was ever a great way to
illustrate contesting, Sweepstakes brings out the best of the contest
world. There's another one coming up, folks, and when I set up my
electronic calendar, the first and third weekends in November are
occupied. When asked how long Sweepstakes repeats, it was an easy
choice; yearly and forever! Thanks for the sweep!

73, Ward N0AX
