This is something I have noticed in contests recently, and just now in a qso with a strong local - after a few minutes, the audio becomes distorted, what we used to call a T7 note.
I have read about distortion caused by banging up against the audio limiter, but this happens even at very low audio output. I also have the impression that it does not occur when I first turn on the radio, and that when I'm transmitting a lot, in contests, it starts to happen earlier and earlier, sometimes emerging at the end of a brief contest QSO. Amp or no, makes no difference, and it appears to happen on all bands. Any ideas? -- 73, Pete N4ZR The World Contest Station Database, updated daily at www.conteststations.com The Reverse Beacon Network at http://reversebeacon.net, blog at reversebeacon.blogspot.com, spots at telnet.reversebeacon.net, port 7000 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
