Radio bleed

[Archimago]

I am starting to notice that i am getting a faint sound from one com radio channel bleeding through when other channel is selected. Ie. I faintly hear the Asos from channel 1 while monitoring channel 2 and even if I switch it around I can still her it faintly on channel 2. Yesterday I noticed that it now receives the nav identification morse code faintly on both channels.
Not sure if this is related but I have also been told that my radios come in weak to everyone else (sounds okay to me and pax). I have a pair of 170b Nav Comms and KMA 24 audio panel
I am hoping its the audio panel which I think could be switched out cheap especially if I go with another kma 24.
Is there anything else it could be?

Next time you hear this, turn the volume all the way down on the bleeding receiver...if it goes away...audio panel is not muting properly.

PMA makes a nice drop in replacement for the KMA24... I love mine.
