Connex 3400 no TX, no RX audio, RX while keying up ‍♂️

[Chris Lawrence]

No transmit. Receive works properly (S9 reading w/ 100 microvolts input) but virtually no receive audio - maybe 2%.

Upon keyup, TX light changes to red but the receive continues to receive. Nothing changes but the light.


PA works. No talkback.
Connex 3400. Ranger 360015c board. How can I help?

PLL out of lock?

I’m going to get back to it tomorrow but it something that happened out of the blue. It seems like something isn’t switching (?)

Fixed. I don’t even know. Cut all cable ties, removed front bezel and frame, noticed the display pcb was not plugged in completely — probably my doing when removing the bezel. This setup is unique to the 3400 but is reminiscent of the 959 display board with 20 or so pins. Reflowed solder joints galore. Made sure all plugs were seated fully. Voila ‍
