[Elecraft] K-3 Lost KPA3 power output

[Art KZ5D]

Thanks Rick for the response.


I was sitting here writing that email and doing some other book work with the rig still on. After finishing the paperwork, I hit the key once more and the power seemed to return. Maybe a thermal shutdown? Or?? I'll keep an eye on it for the next few days to see if there is a reoccurrence.


I appreciate the input.


73,


Art

Check the circuit breaker on the rear?

Tiny iPhone keypad, sorry for typos

fine. Instantly the output went to zero. Tried a reset. Still zero. I checked 
the Config menu setting under KPA and it is set to PA nor. Lowered power to 10 w 
and the output is fine. Adjust it past 12 w and the output goes to zero.
