[Elecraft] K2 KAT2 P-out readings?

[Don Wilhelm]

Joe,

Are you using the TUNE button when you make those measurements, or are 
you doing CW and send 3 or 4 dots to assist in leveling the power and 
then measure during a key-down period.
There is a difference. The K2 must have a bit of output before the power 
levels out.  With TUNE, there are no breaks to level out the power and 
you get whatever came up when the button was pressed - that will be 
close, but try 3 or 4 dots of keying before measuring and I believe you 
will find the power much closer and less erratic.

If the power does not then follow the power requested knob, tweak the 
KAT2 forward power pot a bit - that is the indication of power output 
that is being fed back to the K2 microprocessor.

73,
