[Elecraft] K2/100 RF output varies

[Don Wilhelm]

Mike,

Check the KPA100 manual - during TUNE the power is reduced to 20 watts.  
If you need to TUNE at full power, you can either press the TUNE and 
DISPLAY buttons together, or rotate the power knob to the power level 
desired after the TUNE operation has started.

73,
Don W3FPR
