Here are my plans:
Run a shielded cable from Mic Socket direct to Audio Hat Mic pins.
Use back accessory IDC socket and run ribbon connector from there to Key inputs, Ground, and then a ground and wire from ribbon over to PTT in socket.
Tnx for that hint Dr. Bill. That should be a bit cleaner, no need for 1/8 TRS cable for Mic.
Cleans up busy side of Main board a bit. I will twist ribbon wires also per Dr. Bill.?
