    Try running the system from batteries and see what happens. I had a similar problem once and it was fixed by building a really good power supply.

    The system does run on batteries. That doesn't mean there aren't other sources of noise on the board but during troubleshooting I reduced or removed all of them to the maximum extent possible. I still think that has something to do with it but it is beyond my understanding and despite my curiosity in finding the cut and dry reason for everything, I just don't have time right now. It might be a retirement project of mine.
