Thanks for the ideas Evan. I do appreciate everyone's desire to help. I'll post another issue with a QDX soon and see what comes of it.

Hi Cliff,

Sorry, I do not have any other ideas.? This one may need a response from Hans or someone with more information than I have.? On the surface, it seems like a Si5351 issue, though it could be the codec as well.? Communication with the processor appears to be interrupted.? Another possibility is an intermittent short.? The boards are so cramped that it is possible when flexed, they are losing connection with the processor.? This is all speculation on my part, so please use it as potential areas to investigate.

Good luck in finding the issue.
