QDG - What's Your Darn Grid? Bernd DF2ZC notes that Laurent F6FVY has
programmed a tool (http://f6fvy.free.fr/qthLocator/fullScreen.html)
based on Google Earth so that clicking on any spot on a world map
automatically displays the corresponding full grid locator. Adjust
the map to the desired resolution and click on the spot you want. A
small window pops up with longitude, latitude, and grid. (If you have
pop-ups blocked, you'll have to press the Control key while
clicking.)
More contest videos! Stefan DL7AOS has uploaded the DP9I WPX 2006
contest video to YouTube.com at
http://www.youtube.com/watch?v=qixA4vVDf-s. Since DP9I is a portable
M/M setup, setting-up takes 3.5 days, taking down half a day. Lots
of antenna shots and operating.
Dick W7ZR has just updated http://www.w7zr.com/ with new slide shows
including CQWW SSB from CN2ZR. These might take off some of the
winter chill!
The Northern California Contest Club (NCCC) runs Thursday night
sprint practices that have become quite popular. The schedule of
events (some Fridays are included) through February is now posted on
the NEXT NS page at http://www.ncccsprint.com/next_ns.htm and the
general rules and further info at: http://www.ncccsprint.com/
(Thanks, Ken N6RO)
For contests that run on an "ordinal weekend" (first, second, last)
of a month, the future dates are predictable. Bruce WA7BNM has
published a perpetual contest calendar showing the future dates of
such contests through 2016 at
http://www.hornucopia.com/contestcal/perpetualcal.php
When you consider making year-end charitable donations, don't forget
to ask if your employer has a matching donation program. You may be
able to double your contribution - even to radio-related
organizations like the ARRL, AMSAT, and so on.
URL of the Week - Snowed in? Here's just the Web site to pass the
time. The November "Monitoring Times" Digital Digest column is titled
"What's That Sound?" and includes just what you need. Leif Dehio
seems to have recorded and posted (http://www.signals.taunus.de/)
samples of just about every digital mode active today. Now you can
identify just exactly what those blurbles and bleebles are doing! My
favorite is The Chinese 32-tone MFSK 37.5 + 75 Bd. (Thanks, Cortland
KA5S)

TECHNICAL TIPS AND INFORMATION
-o-- --- oo- o-o o -o --- - - o-o -o-- oo -o --o
The days of those simple "choose your Q-point" Class-A audio output
amplifier stages are history. In case you hadn't noticed, a lot of
audio gadgets now use a switch-mode Class-D output stage. If you are
the electronically inquisitive type, there is a good design article
on these circuits at http://www.electronicdesign.com/ if you enter
'13874' into the Drill Down ID window.
Another interesting article ("Thermocouples Join Forces") about how
thermocouples work in the 6 November issue of Design News at
http://rbi.ims.ca/4939-527 Thermocouples are used in some high-power
radio gear to manage thermal issues, so a little know-how can come in
handy.
Discussing whether it's better to use high/low pitch and wide/narrow
filters when copying weak stations, Jim N2EA offers the
slightly-edited following. "Depending on the statistical nature of
the prevailing noise, you may hear better with a lower frequency OR
with a higher frequency. It isn't always the same. Moreover, despite
our tendency to use tight filters, they may not be the best for small
signal detection. First, the brain needs a fair statistical sample of
the noise, to be able to compare signals to it. A narrower filter may
not provide enough noise input. Second, narrower filters may have
ringing and phase distortion, which confuse the brain...such that the
SNR is NOT improved with the narrower filter. Widening the filter and
shifting to a higher pitch often brought the desired signal out of
the noise, even though I prefer listening to a lower pitch. Try both
approaches before you give up."
Continuing the consideration of pitch sensitivity, Eric K3NA relays
that "The ear can resolve nearby tones more easily at low frequencies
than high. Two tones separate by 10 Hz at 1000 Hz are only 1% apart,
but at 200 Hz they are separated by 5%. There are many conflicting
factors at play here. A just-noticeable-difference in pitch depends
on frequency, volume, duration, and the speed at which frequency
changes (for a changing tone). As a result, there is a band of
frequencies for which we have maximum pitch discrimination. If you
want to measure this for yourself, take the test at
http://www.ucihs.uci.edu/hesp (You must use Internet Explorer for the
test.) Click on "Hearing Test" at the left and pick "frequency
discrimination". The other tests are fun, too."
Pete N4ZR contributes this tip to help others avoid an irritating
"oops" when installing chassis-mount SO-239 connectors. "I wanted to
use single-hole SO-239s in one box, and found that the ones I could
get had the thread on the outside - so you would stick them through
the box from the inside, and then put the nuts on to hold them in
place. The trouble was that with the thick walls of the box, the
amount of thread remaining was insufficient to pull standard PL-259s
down tight against the jacks causing intermittent contacts. You can
get SO-239s that have the thread behind the fixed flange, but ask
specifically before buying." Short UHF bulkhead connectors with nuts
on both sides are also available if the interior connection is to a
PL-259. (Thanks, Mike W0MU)
To keep a turnbuckle from loosening up, put a loop of cable through
both eye bolts (or the guy cable thimbles) and the body, then clamp
the ends together with a cable clamp. (Thanks, Jim K0XU and others)
Sometimes components need to be installed directly on the ac line,
especially capacitors for filtering. How do you choose an adequately
rated part? The folks at http://www.justradios.com/safetytips.html
have assembled an excellent collection of safety information on
line-rated capacitors. (Thanks, Roger N1RJ)
TECHNICAL URL OF THE WEEK -- Want to give EME a try, but can't put
the necessary station together. Tree N6TR contributes couple of
samples of EME signals at http://web.jzap.com/k7rat/rateme.html that
might be interesting to listen to. If you are "trained" at hearing
weak signals, you should hear them FB. Untrained ears take awhile to
finally get it.

Just In Time
I was browsing through the usual collection of holiday catalogs and
email offers when it struck me...why don't we have a good collection
of radio board games? You know, the kind with the complicated
instructions in the lid (no offense intended), a game board, a bunch
of oddly-shaped pieces, and stacks of cards? Imagine a "Games" aisle
at the local radio emporium...just in time for the holiday season!
Log Checkers - each player gets three kinds of pieces called "U",
"B", and "N". The game starts with each player submitting a log of
QSOs that the other players try to bust by playing U's, B's, and N's.
For each busted QSO, you lose a turn in Penalty Land.
DX Operation - try to extract a contact from the electrified pileup
hole while the game shouts "UP!" and "LID!" then drop it "In the
Log." Other players are trying to make their own contacts at the
same time, so everyone has lots of fun!
Get A Clue - Players try to guess the actual call and frequency of DX
operators that aren't signing their calls. "I called 8X8AA on 14.195
with 100 watts and a dipole!" If the call is wrong, other players
heap on verbal abuse in multiple languages.
Trivial Pursuit - this is the name our spouses have given ham radio,
so you already play!
Handy Land - Flip the memory channel spinner and try for a contact on
a local repeater. You are looking for Your Buddy, but may meet a
Commuter, an Old Coot, or even a New Ham - special bonus points for a
First QSO. Lose turns for encounters with trolls and yakkers!
Searches and Pounces - Try to work your way up the band, collecting
multipliers as you go. Watch out - you may get bitten by a packet
pileup and slide back down the band!
PSKtionary - Teams take turns trying to identify digital modes by
sketching their waveforms and protocol state diagrams before the
retry time expires! Hilarious. Really.
SuperCheck Scrabble(R) - Draw one call sign letter at a time while
the game board displays possible calls. If you draw a valid call
sign, you log it! You get double call scores if you guess the
correct call before all the letters are drawn. Special advanced "Top
Band" version gives the letters in random order in the presence of
deafening noise crashes.
Frequency Monopoly(R) - my favorite - buy and trade run frequencies
all the way from Ragchew Lane to Bandedgewalk. Solidify your claim
to the frequency by putting up more and more antennas until you've
built a full Multi-Multi. Buy all of the ham radio stores, but don't
forget to pay your electric bill! Each time you tune the band, pick
up 200 more QSOs - unless you land on Frequency Fight!
