I am now running a pm-3000 with GREAT sound using Lightspeed and Bose headphones. ................
The fidelity was the primary reason for the change with no regrets.

Bob, I have the same intercom but am not happy. Is yours absolutely quiet when there is no input?
My problem? P1 and P2 headsets both have some background white noise. It does not get in the way of communication, but it is loud enough to be irritating. If I move the headset to the diagnostic jacks between the radio and itercom, when no one transmits, its crystal clear silence.
It is independent of squelch and volume, and there when the only item powered is the intercom and master relay.
The fact that it is independent of squelch and volume points to it being on the output side of the intercom, not the input side or input wiring? It seems unlikely to be in the headset side of the harness because a ground / dry joint would not produce enough voltage to make an audible noise (I think). I am no expert at this, just looking at it logically and hoping for ideas to check further.
PS Engineering are leaning towards the problem being the intercom, but I would rather do all possible checks before sending it to the USA.
