I met Tom last night on 80m and he just phoned me. He is having trouble with the antenna relay in his linear, he has to knock on it to get it released for receive. I suggested to check the diode but

Bill, I was very lucky that you called up the band! As I posted here already I only do S&P with qrp in this contest as my CW needs more practice to run in a contest. This paid off concerning multipli

If the "every body else" stations run legal power the illegal power from the "big guns" in that case is 1,5MW? The big differences in signal strength are generally caused by location and antennas, no

Be careful with cheap tv cable. Some are just steel wire with a very thin copper layer which does not matter at UHF with the skin effect there. But on 160m you might run into too high losses. 73 Pete
