Hi Kevin and all
Looks like I found the problems.

Good.  That was easy on my part...   <grin>

Where do you pull the disc off for an external Squelch controller and
control system  I have been using pin 15 of the RX connector on the
main board.

Pin 3 of the Audio & Squelch board is Buffered Discriminator audio. This connects to Pin 15 of the Receiver Interconnect pins.
So, you are connecting to the right place.
