[arm-allstar] DIY CM119 pin 48 voltage

[James WD0JB]

Quick question, I hope. What voltage should I expect to see on pin48 COS on
the CM119 chip? I expected there to be at least 3-5volts but when I place a
multimeter in 2.5volt range the needle barely even moves.
The problem I am troubleshooting is ptt and transmitted audio are working
but I can't seem to get recieved audio to register. And I think it is due
to the COS signal not properly being sent.

I hope this makes sense. I've never had to troubleshoot much digital logic
before. But seems simple enough, I think.

I appreciate any help that can be provided here.
