K3 Power out jumps on power change

[Gordon LaPoint]

Hi,
    I'm having problems with my K3-100 with power out.  If Power is 12 watts or less
(100W pa not in use) and I adjust the power out then the power goes to the new level with
no problem, as long as power requested is less than 12 watts.

When using the 100Watt PA if power is adjusted it will cause power to jump to 110 watts
for a second or less, then go to the requested power. This causes my KPA500 to fault.
The problem is occuring with either the power knob or software from the computer.

After the power stablizes at the new level then it is fine untill I change power again.  

This occurs in any mode.  Any clues that can help me fix this?  
SN is 5651, I built the K3 in August of 2011, it worked fine untill the last month.

Thank you,
Gordon - N1MGO

Hi Gordon,

Hopefully it is a simple calibration problem. Redo the Calibrate Transmitter Gain from the K3 Utility program Calibration tab. If you still have problems you may need to touch up the results as directed at the top of page 62 of the K3 manual. Be sure to check every band. Typically the problems will only occur on one or two bands. If you have difficulty with these manual adjustments come back with questions and those that have performed the adjustments will help guide you through.
