Thanks for the clarification. I'd like to assume that your duplexer and cabling have been tuned up with a spectrum analyser/tracking generator and look good on the scope. I have seen cavities get noisy where finger stock rides on tuning rods, but this issue doesnt sound like that. It has been postulated that you might have a TX spur that comes up and causes the problem. I tend to lean in that direction. Since the problem is intermittent, you are going to have to go over everything until the problem goes away. If your radio is at a commercial site, you may find another transmitter involved. In any case, it won't hurt to look at the duplexer, but I wouldn't think that was the issue, unless it has given problems before. Good Luck with it! Keep us posted.
