[Elecraft] K3 sudden. loss of TX power?

[Jon Zaimes AA1K]

I was three hours into the CQ WW DX SSB contest and transmitting on 40 
meters when suddenly transmitter power went to zero. No error codes and 
after a minute or two it came back briefly but then went out again.

The first bar is showing on the front-panel Power meter. The red TX LED 
comes on.

I tried the things suggested in the troubleshooting section of the 
manual to no avail.

No change when I shut if off and waited a bit and turned back on.

Also tried bypassing final amp in the config menu.

I tried it on CW and still no power output (just shows the first bar on 
meter).



Any suggestions?
