I have an ICOM aviation transceiver that has a problem in getting an external microphone to work. The internal mic works just fine. However, when I try to use any number of external microphone or headsets, I can only transmit a weak signal. Also, sometimes during even a short transmission with the external mic, the radio heats up a bit more than usual. Any clues as to what's happening?
