So this "New to Me" Aerobat is turning out to be the project I was expecting. The (most likely original) audio panel in it is basically... inop (old Radio Systems Technology panel). It came with a KMA 24 which I now know is also inop and not worth installing.
So I am looking for a used audio panel which is in decent shape to replace the ancient one which is in there now. What do I really "need"?
2 place intercom, 1 or 2 comms and at least 1 Nav. Marker Beacons would be great too.
Let me know if you have something gathering dust in your hangar!
