If you've not participated in the annual Armed Forces Cross-band
Communications Test
,
give it a try! Military stations like AIR and NAV transmit on
frequencies near the HF ham bands and listen for stations calling on
ham frequencies. Work as many as you can, including a station on the
USS Yorktown - most send QSLs, too!

==> NEWS, PRESS RELEASES, AND GENERAL INTEREST
Hector XE2K/AD6D reports the creation of a new Spanish-language
contest reflector - CQ TEST Radiodeportiva - by EA8AY and EA8CAC. The
goal is to make it easier for Spanish-speaking hams to share
information and experiences in their native language. It is hope that
it will promote and increase the activity from Spanish-speaking
countries all over the world. If you want to participate and share
experiences but your Spanish is not perfecto, no problem, you are
welcome. Please register and share what you think can be good for the
contesting community. Several can help to translate if you wish. En
espaņol, "Hola Amigos - Quiero anunciar la creacion de un nuevo foro
que hace una semana EA8AY y EA8CAC iniciaron que llamaron CQ TEST
Radiodeportiva que es un foro en espa?ol, que esta enfocado en hacer
mas facil compartir la informacion y experiencias en tu lenguaje, que
tambien tiene la idea de promover e incrementar la actividad en paises
de habla hispana en mas concursos explicando y apoyando a los miembros
en los diferentes temas relacionados a el Radio Deporte dado esto por
varios experimentadosy bien conocidos Concurseros no solo de Latin
America si no de todo el mundo. Quedan invitados y espero ver mas
amigos en el Foro para hacerlo mas rico en conocimiento y
experiencias." Please forward this message to your Spanish-speaking ham
friends!
Tim K3LR's video presentation on all of the Contesting Activities at
the 2011 Dayton Hamvention has been posted to
the Potomac Valley Radio Club's web page at
under Recorded Webinars. During the Hamvention, two hours of Contest
University USA in Dayton (on May 19th) will be available live and
online via Webinars courtesy of ConTest University (CTU) and the
Potomac Valley Radio Club (PVRC). The first Webinar - the opening
welcome and first session "Contesting the Right Way" by K1DG - will run
from 8-9 AM Eastern Daylight time (USA EDT). The second Webinar will
run from 4-5 PM EDT and presents Rob Sherwood, NC0B delivering "Contest
Radio Performance" and the closing remarks for CTU. Registration
information will be posted on the PVRC website shortly. Radio-sport
also has a new article
on the contest goings-on at Dayton. I would ask for permission to
reprint the photo of nattily-attired Paul K9PG and Gerry K8GT, but it's
just too awful to print!
Central States VHF Society Vice President Kent WA5VJB
has issued a call for papers for the CSVHFS
Proceedings with a rapidly approaching deadline of May 20. The emphasis
is on smaller papers this years such as "Hints and Kinks", roving and
contest operations, radio modifications, antenna construction, etc.
(from AMSAT bulletin ANS-121)
Dave G3YMC reports that Ukranian hams losing access to several bands
is not yet certain and is apparently an administrative error. The
Contest Update apologizes for promulgating uncertain information.
How time flies. It was about 25 years ago that Doug KR2Q encouraged and
assisted Dick Ross K2MGA with creating the CQ Contest Hall of Fame
. For some historic photos, take a
look at these shots from Buz K2GL's 80th birthday party and Hall of
Fame #1
. A
summary of K2GL's accomplishments is found at the lower right. (Thanks,
Doug KR2Q)
Larry N6NC was working on improving his accuracy at copying number
strings - an important part of doing well in the up-coming CQ WPX CW
contest - and found Morsecat2 by DK5SCI . This
code practice program can be set to blast out number group - just what
you need to get WPXed into shape!
CWops will sponsor the first CW OPEN
this summer on Aug 20-21. CW OPEN is unique in that it consists of
three, 4-hour contests timed to occur under optimal low-band and
high-band conditions in at least two out of three of the time periods
in ITU regions 1,2 and 3. It is a single-operator contest with QRP,
low-power, and high-power categories. The contests will each be
separately scored and awarded. Those who participate in two or more of
the three contests will have their scores aggregated and can also
compete in the combined score category. This looks like fun! (Thanks,
Al AD6E)
The June issue of Popular Mechanics
ran a great article, "When the First Responder Is You" covering a
number of real-world situations that have all been in the news lately.
Getting on the radio is not always what needs to happen first!
W1ZM, Gerard "Jerry" Scarano, of Gales Ferry, Connecticut, has become a
Silent Key at the age of 96. He was an original member of the Yankee
Clipper Contest Club and before that an active Potomac Valley Contest
Club member. The list of call signs that operated from his stations
reads like a who's-who of contesting. Jeff K1ZM penned a nice
reminiscence on the cq-contest reflector
.
AN Wireless Tower Co., LLC has relocated
its operations to a 43,000 sq. ft. facility in Austintown, Ohio. It's
nice to hear of a company outgrowing its manufacturing facility instead
of the other way 'round. Aside from improved shipping times, this move
places the company closer to their hot dip galvanizing and steel
vendors. They'll have easy customer access just 2 miles from I-80 in
northeast Ohio, too. (Thanks, AN Wireless founder, Dan KK3AN)
Bob K8IA reports that the Arizona Outlaws Contest Club
has elected a new slate of officers
for the coming year. Good job!
Steve GW4BLE and Andy MW0MWZ have put together a great website
to play back audio of contest activity
(mostly SSB) from the last eight years or so. The basic building blocks
are from the Writelog contest logging program website, plus SQL log
conversion, Smartphone audio, and other features. Steve notes the
assistance of the CDXC members during site debugging and development,
as well.
Web Site of the Week - At the recent ID State Convention the Friday
night speaker, Lisa Spahr , had a very
interesting presentation about a WWII-era ham public service of which I
was completely unaware. A group of hams was organized to listen to SW
broadcasts from Germany and other Axis powers to listen for POW reports
and relay the information to their families. Lisa's grandfather was a
POW in Germany for 26 months and her great-grandmother found out about
his capture this way. All in all, there were quite a number of hams
doing this - sending thousands of letters - and she is requesting
Congressional recognition of this group, many of whom are still alive.
WORD TO THE WISE
NIB-NOS - could it be a tasty snack? Nope! These acronyms mean "New In
Box" and "New Old Stock" and are used to refer to tubes and used or
replacement equipment.
==> SIGHTS AND SOUNDS
A side trip to the US Air Force Museum is a must-do if you ever attend
the Dayton Hamvention. If you're not heading to Dayton, you can take a
virtual walk-through
of the entire
museum, click by click! (Thanks, Sean N3JQ)
The LU Contest Group recently had its 11th anniversary and threw a big
party. Diego LU8ADX sent a link to his online photo album of the
festivities.
Some attended in costume, like "El Gaucho", Martin LU5DX!
Ace ham photographer, Bob N6TV, published his online album of photos
from the Visalia International DX
Convention - thanks!
Bob K0RC asks, "How much do you REALLY know about the United Kingdom?
You've put many (or all) of them in your log, but just how is that
Kingdom organized, anyway?" Luckily, he also provides the answer in the
form of this 5-minute video
!
If dark matter falls on your foot in the dark, is it true that you
can't tell? This cartoon from PHDComics
refutes the supposition
thus. (Thanks, Tree N6TR)
But can this guy balance it
up there with a Spiderbeam
on it for the entire Field Day period? (Thanks, Tim K3LR)
==> RESULTS AND RECORDS
ARRL Contest Branch Manager, Sean KX9X relates discovering and
repairing an issue with the ARRL 160 Meter contest results for the Club
Competition, "Numerous members of the Frankford Radio Club were
accidentally listed as members of the Yankee Clipper Contest Club. This
appears to be the result of an error on my part during the data
processing phase. The order of finish was unchanged in the Unlimited
Club category; however, Frankford Radio Club is the correct winner of
the Medium Club category. The Local Club category was unaffected by
this error. The online results database
has been
corrected."
Also in the ARRL Contest library, results for the 2010 ARRL 160M
Contest and the 2011 ARRL RTTY Roundup are now online
. Log Checking Reports
for these two events are still being processed and Sean hopes to have
them online in the next day or so. The April 2011 Rookie Roundup
results are also online
- thanks to all the OT's that got on and worked the Rookies. The next
Rookie Roundup will be held on Sunday, August 21 1800-2400 UTC and will
use RTTY!
CQ World-Wide Contest Director, Bob K3EST reports
record 2010 log submission levels. "Contesting continues to be at the
leading edge of spectrum use and technological advancements. Ken can
give you exact numbers. A total of approximately 12,700 logs were
received for the 2010 CQ WW contests. In spite of code not required for
obtaining an amateur radio license, CW continues to grow in popularity
within contests." I'll say! The SSB haul was 6,445 electronic logs and
for CW there were 6,079 electronic logs. As Ken K1EA muses, "Imagine if
we had 1957-1959 conditions!"
Dave W9ZRX needs your VHF+ contest logs for a late
May or early June release of the VHF Super Partial Check and VHF
Prefill databases . Because of the nature
of VHF propagation, he needs logs from a wide area for the databases to
be useful across the country. Please email Dave Cabrillo-formatted logs
from any of the 2009-2011 ARRL or CQ VHF contests.
With a little help from Paul, K8PO, the Boring Amateur Radio Club is
happy to announce that the results of the 15th running of the Stew
Perry event are now available
for your viewing pleasure. Don't forget - there will be a Summer Stew
coming up in about five weeks.
(Thanks, Tree N6TR)
The recent Georgia QSO Party
sponsored a special award for contacting seven of the contest's special
event 1x1 call signs such that the suffixes spelled G-E-O-R-G-I-A (yes,
two "G" stations). The rare vowel "E" turned out to be the difficult
letter! (Thanks, Scott KB4KBS)
The claimed scores for the 2011 WPX SSB Contest
are now available with a
record 5,041 logs and paper logs still arriving in the mail. Claimed
scores can be sorted by continent and category. A search function is
included so you can quickly locate a particular score. The score
calculation process is discussed on CQ WPX Director Randy K5ZD's blog
.
OPERATING TIP
Clean audio saves time! Tip #1 - the power meter needle should move in
sync with your voice peaks, not go to maximum and stay there because
you have the processor maxed out. Tip #2 - yelling makes things worse.
Tip #3 - clean audio will cut your QSO time by two-thirds. Why? Because
everything doesn't have to be repeated and your call sign gets through
correctly more often on the first call. Higher average power does not
also mean higher intelligibility - too often quite the opposite!
==> TECHNICAL TOPICS AND INFORMATION
When is a bus bar not a bus bar? "The Case of the Noisy Bus Bar
" - a
Sherlock Ohms column the April 2011 issue of "Design News" magazine -
takes an interesting turn through antenna theory.
Bill K2TT, Defense Science Board member, writes, "Contesters are
heavily dependent on computers coupled to the Internet, and as a
consequence, are vulnerable to the increasingly burdensome problem of
cyber security. The DoD's National Security Agency (NSA) has published
a useful document for consumer-level cyber security, "Best Practices
for Keeping Your Home Network Secure
."
This document could be useful for readers of the Contest Update."
The April issue of Scientific American
included an article titled,
"Solving the Cocktail Party Problem" about extracting just one voice
out of many and how hard that is for computers to do. Any phone
contester could have told them that! In a similar vein,
"Cognitive-Radio Games" in the same month's IEEE Spectrum
speaks to the methods by which radios will
share crowded spectrum. That one's easy, too - give your full call,
always!
Weather maps are all over the web, but what about maps from the past?
You're in luck as NOAA has an online archive of weather maps
open to the public. Now you
can play back that great tropospheric opening!
An interesting conversation ensued on the Towertalk Reflector
about digging
a square hole ("Mike Mulligan and His Steam Shovel
",
anyone?) with a wide variety of related (and un-related) topics being
explored. Just check the archives for the topic "Digging a Hole with a
Backhoe". Where to find operators able to make a nice, square hole?
Gravediggers and septic-tank installers were mentioned, the point being
to hire someone who digs square or rectangular holes for a living.
Scientists at Stanford University have developed a prototype
rechargeable battery
that runs on water. Nanotechnology is used to extract electricity from
the difference in salt content between fresh and salt water. Gee, we
can extract electricity from on air, water, and fire...if somebody will
just add an earthen battery to complete the quartet, Aristotle would be
proud!
Technical Web Site of the Week - Mitch WB9IQQ
, Jeff "Mightyohm" KF6PBP
, and Andie Nordgren
have released a "Soldering Is Easy!
"
comic book. It's fun, and funny, easy to read, and Mitch hopes it will
make it really easy for anyone and everyone to learn to solder, even if
they've never built anything before. Previously, they developed a
single-page comic reference sheet, now in 6 languages, and all Open
Source and free for the downloading! (Thanks, Mert AC7KY)
==> CONVERSATION
Ham Hearing Aids
I wear hearing aids in both ears and have for nearly twenty years -
even during contests! Here are a few tips and thoughts on hearing aids
that might be of interest to those of you who need a little help with
your hearing or who aren't getting any younger and thinking about it.
Bear in mind that my hearing loss is basically a high-frequency
roll-off above a couple of kHz. Your specific need should be evaluated
by a professional and may have stronger bearing on what type of hearing
aid you need than the following topics.
Digital or Analog? There's not even a question - get digital aids. They
use similar signal processing to what we have in our radios, with
similar effects on the audio output. This is now the dominant
technology and rapidly replacing analog instruments. Your main
questions will be about the signal processing features of the signal
processing, discussed below. Digital aids act as a multi-band graphic
equalizer, very similar to those used in audio systems. In addition,
the digital aid will have several "programs" that set up the aid's
features in different ways for different environments. The hearing aid
technician will explain this to you in detail. It would be a good idea
to make it known that you have some technical background so the
discussion can take advantage of your expertise.
Behind-the-ear or In-the-ear? I started with behind-the-ear aids
because at the time, the smaller in-the-ear aids were too expensive.
This has changed, with the new "open ear" style offering a lot of
features without the molded housing that goes in the ear canal. I have
tried the open-ear style and I do like the sound quality. I changed to
in-the-ear aids, however, because placement of the microphone in
behind-the-ear aids tends to skew its pattern to above, behind, and to
the side of the listener. This may not help with face-to-face
conversation and dead-ahead audio sources, such as TV. In-the-ear aids
can take advantage of the natural focusing provided by the external
ear. Behind-the-ear microphones also don't help as much with most
telephone handsets - you have to learn to hold a cell phone farther
back so that the speaker is closer to the aid's microphone, for
example.
Behind-the-ear aids are also generally quite uncomfortable with
earmuff-style headphones that many of us prefer in the radio shack - if
they can be worn under earmuffs at all. If you have to take the aids
out when wearing headphones, they can't help you with receiver audio.
So I wear a mid-sized, in-the-ear aid that has worked out well. Many
vendors will let you try open-ear-style aids as way of finding out what
features and settings you like whether you buy behind-the-ear or
in-the-ear aids.
Signal Processing The first component of audio processing you'll notice
is compression or AGC. Compression is good in a hearing aid because it
prevents overload and distortion. The price is somewhat increased
background noise. In addition, if you are using the aids with a radio
the two AGC systems - one in the radio and one in the aid - increase
the amount of compression and the interacting time constants of the
compressors can actually hurt intelligibility of the received audio.
You'll also notice that just like a ham receiver's DSP, some of the
features of the hearing aid will color the audio in perceptible ways.
For example, feedback cancellation is a nice feature but it will also
try to get rid of single-tone signals like CW! The effects of noise
reduction in the hearing aid are also similar to a receiver's DSP. You
get used to them and the benefit of reducing noise generally outweighs
the presence of artifacts. This is where the different programs of the
digital aids become really handy.
While the advanced features are great in normal conversation, they get
in the way when on the radio, so be sure to have one program in which
compression is turned off along with feedback cancellation and other
artifact-inducing features. Say to the technician, "I want one program
that only has gain and frequency response correction." If you have
enough programs, you might even want to try to set one up for CW and
one for voice! It would be a good idea to take an audio player with
recorded CW and voice signals to use as the aids are set up for you.
The gain-and-frequency response program has also turned out to be the
right one for me to use when I'm listening to music, as well.
Selecting a Vendor There are number of good hearing aid companies and
the mid-range to high-end hearing aids are all very good. I initially
selected independent local hearing aid companies with good prices and
excellent service, but both struggled and were eventually purchased by
a national manufacturer. My current set of aids is of a national brand
with offices in shopping malls around the country. Because I travel
frequently, I like knowing an office is probably handy and I have had
to get a microphone port unplugged while on the road. Your
circumstances will dictate your choice but I strongly recommend making
service after the sale a primary evaluation criterion.
Do I Need Them How can you tell if you need a hearing aid? Ask your
family for their honest opinion and then listen to what they tell you.
"Green-bar guys" are an industry legend, referring to the volume
control on the TV that they are always turning up and up and up.
Meanwhile, they insist that their hearing is just fine and why does
everybody mumble? If you're not hearing the phone, if you can hear
someone talking but can't understand what they say, if the pileups all
sound like mush - you probably need help with your hearing. One way to
experiment before trying a hearing aid is a pocket graphic equalizer,
such as the Koss three-band Portable Stereo Equalizers that can be
found on the Internet for about $20. Wire it up to your radio or audio
player and experiment with the settings. You may find that a little
boost on the high frequency channel or dropping the low frequencies
helps or maybe just some additional gain is what you need. The cost is
low and you'll learn something without having to make an office visit.
Summary All of us are getting older and hearing often takes a hit on
the way. Younger hams that have grown-up with ear-buds cranked up to 11
are discovering that those fragile hair cells of the cochlea have worn
out early. Meanwhile, the perceived stigma of wearing hearing aids is
largely non-existent as people are wearing headphones and earpieces
everywhere you look. Good hearing matters not only on the radio but in
our personal lives, too, especially to the people around you. Take
advantage of what is becoming ubiquitous technology to restore your
hearing.
