--------------------- Was the MCU (U6) installed in that control board when you received it? If so, the entire board needs to be treated as an "ESD Sensitive" device since a number of the pins on U6 are hanging open at the connectors when it's out of the K2. And ESD damaged chip will produce all manner of weird results. Indeed, U6 might not be the only IC exposed to that sort of failure with the board unplugged. A treat the boards just like I would any sensitive chip when they are unplugged. Don't forget, you have Elecraft service to lean on if you choose. Gary has all the resources to check and debug the board.
