Connex 3300 - No RX Audio

[Chris Lawrence]

[edit] Resolved below

RX works
RX audio does not work
The actual volume control pot is working properly adjusting between 0-50kohm approx

Tx works
Tx audio (modulation and talkback) work
PA Audio works when talking in mic

What can I provide you with to help fix the issue.
I can hear a pop when turning on power.

Meet the two solder pads that should have been soldered together. Held together by a flake at one time.

I've also seen that more than once before myself. I take it that fixed your issue?

Yes. It was strange because the voltage on the the trace on the board that comes from the “switched” leg of that control pot was showing 2.7v. My first thought was a shorted component was drawing down the power. The radio would actually turn on, but dim. Thats wierd.
