[Elecraft] K2: Heat On Digital Modes

Thanks for the quick reply.  Fortunately, it appears that uncontrolled power 
output is not the problem.

And yes, it is a K2/100.

I connected the rig to an MFJ-941E Versatuner II and connected the Versatuner to 
my antenna.  I tuned to a 1.1:1 SWR using the Versatuner and then measured 
forward power on CW key down at various power settings.  The forward power 
transitioned smoothly from just under 20 watts with the rig set to 20 watts to 
just over 90 watts with the rig set to 100 watts.  I probably need to do some 
calibration, but it appears that the power control is working.  

I also tried it with PSK and Olivia transmissions and the Versatuner was showing 
around 25 watts when I had 25 watts set on the K2's power control.  I upped the 
K2s power control to 40 watts and saw an increase in forward power on the 
Versatuner to about 35 watts or so.

I can get my hands on a real wattmeter in the next few days if you think it 
necessary, but these tests would imply that I am not experiencing uncontrolled 
power.
