Power problem

[Bill Turner-2]

My K3 has developed a power problem. I first noticed it on 20 meters.  
It would not reach 100 watts, but was stuck around 60 watts even using a
dummy load, and the power would "pump" up and down about ten watts.

I then went through the power calibration procedure and it failed at 5
watts with the error message "Calibration failed because the transmit
power did not reach the expected level".

Time for a trip back to the factory?  Suggestions?

Bill,
I had this problem while building my K3 recently.

I spoke with the factory as it was fine when first tested.

It turned out that I had not tightened all the screws down when
refitting the PA. Once tightened down it came back to life.  During my
conversation I was also told to check that the screws on the regulators
(bottom panel) are tight enough.
