The Terra TXN 920 Installation Drawing shows an 'interphone key' input in
addition to a mic key input. It is pin 14 on connector P1 (The mic key is
pin 6).
I would guess that grounding the interphone key pin sends mic audio to the
radio speaker output without keying the transmitter but, I would like to
know for sure. Would someone please tell me what the interphone key does
and how it is used?
Thanks,
Mike

The traffic audio alert in the Garmin 330 mode S transponder shows two ouputs,
one marked "high" and one marked "low". What does this mean?
