[ICOM] TNC and Mike Distortion in IC728 and IC735

[J. Coote]

I've run several KAMs in different IC735s and in one IC728.
One source of irritation is the TNCs usually have to be unplugged
from the accessories connector when using voice, otherwise there
will be distortion and "crud" in the transmitted audio.

I need a way to keep the TNCs plugged in- so our EOC radios
can be used in voice or data instantly and won't start looking like science
projects.

I'd appreciate any fixes.

Thanks,
Jay
