Terry, If you are using LMR for feed-line you will most likely have trouble eventually. But the problem you described sounds more like static electricity build-up.. read this article.. <http://www.repeater-builder.com/antenna/static.html>

I had a question from a friend which I can't answer ... I've never heard what he's referring to. Is there anyone here who can confirm or correct this: "One of our local repeaters has a popping noise that gets severe during high wind conditions. I have "heard" that LMR type coax can cause this noise. Various reasons have been discussed including the dis- similar metels between the inner and outer shield, also nicking the copper clad on the center conductor. I am told this condition only occurs on a repeater using the same coax for Rx and Tx. The repeater in question has a very clear signal when transmitting, the noise only comes on while receiving a signal, both with and without modulation. This leads me to susspect the "dis-similar metals" theory." I'd appreciate any insight you may have on the question, preferably directly to me Thanks in advance Terry WX7S Yahoo! Groups Links Yahoo!
