Gentlemen, If anyone happens to hear me calling a station way off his TX frequency --or on top of your run freq(!)-- during the Stew Perry, kindly send me a quick e-mail telling me so. (And you don't have to be nice about it. :-) The time, freq, and amount of freq offset would also be appreciated.
I couldn't reproduce this after many tests this afternoon and evening; but earlier it seemed that my IC-765's CW TX frequency shifted in relation to the center of the 250 Hz CW filter (or perhaps it was the other way around). I'm getting ready to finally jump into the SP, and I don't want to unknowingly QRM anyone. If necessary, I will use my R-4C for every S&P contact during the rest of the contest --in lieu of transceiving on the Icom-- to ensure this isn't happening. I DO plan on regular tests with the R-4C; but since it's so slow that way, I'd rather not do that for every contact unless it is necessary. (Of course, if we call a station who is working split, that's different.) Last week on 20 meters SSB, I had to readjust my PBT for a short time in order to make RX signals sound right. But they told me I was not off frequency. My guess is aging trimmer caps in the PLL section, a known problem in older com rigs. (or Alzheimer's, a known problem in some men my age. ;-) Once the transceiver warmed up (like it is now) the problem went away. 73, Mike www.w0btu.com _________________ Topband Reflector Archives - http://www.contesting.com/_topband
