From the original Tentec drawing;
Pin #1 is mike HIGH
Pin #2 is mike LOW
Pin #3 and pin #4 are connected direct to the PTT switch.
The shell should be used as the shield/ground.

A while back someone here had the wiring data for the 707 mic.
I had a copy but can't find it now that I need it.
Any help appreciated
Thanks Paul K0UYA
