Hi Lee, Do you also have a reduced RX signal level on 30 meters as well as 20 meters, at least by comparison with your KX3?
Since the TX output is OK, I will hazard a guess that one of the relays in the 20/30M bandpass filter is not making good contact or has developed a weak solder joint on the RF board. While that should also reduce the TX output, the TX Power control loop may compensate enough to make the added loss through the relay less noticeable. I would carefully inspect all solder joints in the 20/30M bandpass filter circuit, maybe do the same for the lowpass filter. I would try gently pressing on the relay casings while listening to a good strong signal on 20 meters and 30 meters to see if there is an audible change in RX signal level. 73, Mike, K8CN ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
