I was up flying yesterday in a busy flightseeing area, Knik Glacier, and had a friend in a Supercub with dual comms. It seemed like it would be really nice to monitor a second station. We were talking on a second frequency but there is a CTAF for the area. It would be nice to be able to listen to both.

Has anyone set up a system like this or have suggestions. I have an old A4, I was thinking of maybe just running with the rubber antenna and just plugging the audio into my headset or intercom. I wouldn't necessarily need to transmit on the second radio.

Also I had a battery go dead in my intercom. My sidetone disappeared or was garbled. I thought the Sigtronics was a fail safe so you could still talk through it, but that wasn't the case, it seemed I could not transmit with headset either in Xmit plug or Mike nearby, negative response from radio checks with other planes, have ICOM doggle with PTT and an A6. When I unplugged from the intercom and directly to the ICOM adapter everything worked fine again. Maybe it's an older model with out the fail safe feature.

Thanks for any thoughts
