My Terra 760 Radio had a built in intercom. All I had to do was wire in a squelch and volume control and a PTT relay circuit based on a diagram supplied by Terra. Unfortunatly, Terra was bought out by (Garmin? I think) and no longer produces these nifty radios.
If I can dig up the manual I can scan it, but the primary part of the intercom (VOX circuit) was built into the radio. I just had to buy two relays and two potentiometers[sp?].
