In some Tentec radios there is a problem combining PTT return and
microphone return and shield return, going to the PC board, not to the
case and that injects RF into the audio board. The cure as I recall is
to separate audio and PTT returns from the shield and ground the shield
of the microphone cable to the case. But I don't know this goes back as
far as the Omni V. I think it was something new with the early
production Orion.
