[TenTec] Orion and Heil Goldline GM-4 studio microphone

[Mark Erbaugh]

Eric,

I'm also using a GM-4 and Orion. My CC-1 cable also started life as a
Kenwood cable.  I connected the mic's PTT switch between the PTT pin 3 and
the ground pin 2. I use the 1/4" PTT jack to connect to a Heil footswitch
and use that for PTT control rather than the PTT button on the mic, although
I did use that before getting the footswitch.  I've not had any reports of
RF in my audio.

73,
Mark
