While the channel is in the desk, if I press the CH IN on Dynamics, I lose audio. But, when I plug it into the test jig the audio seems to pass fine? Is there something different about the Desk vs test jig that I should now about?
 
Must be some connection I would have thought.
Try putting the channel elsewhere in the desk and see if it still does the same thing. If so, swap the dynamics card with another.
If it's OK elsewhere, then maybe the adjacent channels are affecting it.

maybe if gate of the linked channel is off it would mute your signal...

JS

The link button just shorts the side-chain to the module on it's right, so they share control voltages.

You have to imagine the link to be the greater of the two side-chains wins, more that one dynamics controlling the other.

Most of the time it's just dirty contacts on the 611 motherboard/ upper and lower bus cards.

Recommend cleaning the gold pins with contact cleaner, this fixes this kind of problem 9/10.

Also.. the small gold contacts on the PCB that holds the Dynamics/EQ switching can get funky, this is removed with one small screw. Normaly use a small brush and contact cleaner.
 
The problem seems to follow the Dynamics card. Meaning, if I swap the cards around... the "channel slot and 611 module are fine.

You really need to get the Module on an extender, and scope the path in and out of the bad dynamics card, and see where the signal drops out.

Yep!
