AM, the forgotten mode
As we all know by now, it has been great on 10 meters lately. Memories dating back to the seventies / early eighties started to bubble up like methane gas from a swamp. I can still draw my Sharp 6-channel CB transceiver out of my head, without missing even one detail. It only produced about 3.5 Watts output, which was sent into a 1/4 wave ground plane. In AM, of course, as that was all we got at the time. I remember the soft, pleasant background noise. No squelch required. QSO’s around the world could be made 24/7.
Yesterday and today I decided to keep an eye on AM signals and tuned my FT-7B to the lower part of 29MHz. Without much trouble I worked three stations. UR5QGC (Ukraine) was added to the log yesterday, who was working with a home made transmitter and an old military receiver. Today I picked up N1EU and W9UD, both in the USA. 20 Watts and a vertical proved to be enough for a reasonable signal report. This solar cycle is not as good as the one I mentioned earlier (the band closes about 1 hour after sunset), but great nonetheless.
