Both addresses were published. If you get an "unknown recipient" error on your log email, that is probably the reason. (Thanks, Stan K4UK) BUSTED QSOS o Not exactly a perfect issue last time, but shinier than the preceding issue. CONTEST SUMMARY (Rules follow Commentary section) December 16-26 - North American Meteor Scatter Contest - Holiday Spirits Homebrew CW Sprint - OK DX RTTY Contest - PSK31 Death Match - Russian 160-Meter Contest--CW/SSB - Croatian CW Contest - Lighthouse Christmas Lights QSO Party - DARC Christmas Contest--CW/SSB --o- ooo - --o- ooo - --o- ooo - -oo o NEWS, PRESS RELEASES, AND GENERAL INTEREST - oooo o o-o o- - o ooo oooo o o - -o- 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.

Don't forget to add your own Soapbox comments and photos to the ARRL Contest Soapbox page at http://www.arrl.org/contests/soapbox oo oo-o oo - ooo -o --- - -ooo o-o --- -o- o 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. o- -o-o -o-o oo- o-o o- -o-o -o-- oo ooo o--- --- -ooo CONVERSATION --- -o o oo -o -o-o --- -o - o ooo - oo -o --o 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! 73, Ward N0AX -o-o --o- - o ooo - -o-o --o- - o ooo - CONTESTS -- 13 DECEMBER TO 26 DECEMBER 2006 -o-o --o- - o ooo - -o-o --o- - o ooo - Note that the following abbreviations are used to condense the contest rules summaries: SO - Single-Op; M2 - Multi-Op - 2 Transmitters; MO - Multi-Op; MS - Multi-Op, Single Transmitter; MM - Multi-Op, Multiple Transmitters; AB - All Band; SB - Single Band; S/P/C - State/Province/DXCC Entity; HP - High Power (>100 W); LP - Low Power; QRP (5W or less) HF CONTESTS Holiday Spirits Homebrew CW Sprint--sponsored by the QRP ARCI, from 2000Z - 2400Z Dec 17.
