But you do get PA audio?

Both Pin 2 and Pin 4 would show as Ground at the JACK (pin side) - nearly a dead short to each other then retested to a shield can, like one of the main IF cans in there, it's case tests as a short - inside the radio - proving true Board ground.

Now with PA working - do you hear receive thru the PA? You couldn't transmit to the other radio - but can you hear the other radio thru the PA speaker when you talk on that other radio?

I'm trying to confirm that Receive works -

Do you have S meter showing indication?

When you key up the other radio you can hear it thru your radios PA speaker?

PA audio - you say you can hear yourself thru that Microphone - like Talkback - only thru the PA speaker.

With these three conditions, if yes, then - the wiring OF THE SPEAKER is suspect.
