    Likely problem is RF getting into the intercom, so check earth braids there first. Ferrite beads placed over certain cables may help, but this cure is reserved for dealing with improper equipment or installations. The Microair radios do, as part of their "normal" function, transmit noise coming from both mics regardless of which ptt was pressed, but this noise is minor (with a correctly adjusted mic gain) and not the type of RF feedthrough noise you describe. I'm not quite sure whether his radio has also its own built in intercom, which should be disabled, or used instead of the external intercom.
