Guys:

If anyone would like a PDF of the cable wiring email me off the 
reflector and I will get it to you. It helped me a lot.

> I rewired my D104 Mic with a 8 Pin cable I got from TT..the ESD 
> issue has gone away. Pin 5 on the O7 is chassis ground and is the 
> pin to use for PTT common and Mic audio shield. The cable has two 
> wires within the shield for Mic - and Mic +.. I didn't realize the 
> connectors on the front of the 07 are not connected to chassis 
> ground. When Jack Burchfield of TT explained this to me the ESD 
> solution became much clearer. Now the ESD  bleeds to the chassis 
> ground via Pin 5.
