Hi Brian, Make sure all of connectors between the front panel and the main pcb are mated / seated correctly. I had some unusual intermittent problems, including no RF out, due to bad connections here. In my case, removing the front panel and giving the connectors treatment with deoxit solved all of the issues. MY S/N is early 3000 and has tin plated connectors. I believe the later units have gold connectors.
Just another thought, check that all of the TMP cables are seated fully. If you are still stuck, I would suggest a phone call or email to Elecraft support. I have always found their product backup to be exemplary.
