My plane is a 1976 Cessna 172M (Skyhawk), and the Narco is a slide out
replacement for the Cessna radios.

I have PTT on both yokes with intercomm jacks on both sides. The
problem seems to exist in both sides, although that doesn't mean they
both don't run to a common relay??? I can certainly look... ;-)


This is seeming more and more like a likely possibility. I'm
considering taking the plane back to the avionics shop and seeing if
they can troubleshoot an issue between the tray connector and the
radio.

Thanks much for the response!
