Bob I had a similar experience for a few minutes during set-up of my new K3. In my case I had not installed a roofing filter at FL1, choosing instead to leave a gap there for later installation of a wider filter. The firmware default assumes a filter will be present at FL1 and the absence of one made the RX deaf and provided 0W RF out on TX. Once I had changed the default filter location, which I did using the Elecraft K3 utility, the RX came to life and TX Gain Cal ran just fine producing the required 5W output on every band.
This might possibly be your problem. Good luck.
