My Flightcomm 403 intercom system is crystal clear with everything running. As soon as I wired in the audio out from the MGL Odyessy EFIS, I hear clicking and background noise(from processor clock?) and it is very annoying. I have tried inputing the audio out on the phone in on the intercomm, on the
aux in , and on a mic input, but it is always the same. If i put a
ferrite , 10k resistor and capacitor in the line, it is reduced, but
still there. I have also tried with and without grounding of the audio
line.

Any suggestions ??
