I’ve got a weird problem with my intercom or radio, not sure which one is the offender. It’sa PM1000 II intercom with an Icom IC-a200 radio. All works normally when I first turn on the avionics switch. However once I transmit, my back seater cannot hear me, and I have to turn off- then on the intercom to restore the intercom function. (I can still hear the intercom from the back seater). Here’s where it gets weird, When I turn off the intercom, the radio becomes “Hot” meaning it’s transmitting. I have verified this by turning off the intercom and speaking to ATC. Any suggestions on where to start? Thanks in advance!
