[Elecraft] [K2] K2 Always full power out

[Don Wilhelm]

Dave,

The KAT100 power output is not sent back to the K2 unless the KAT100 is 
operated without the KPA100 in-line.

With the KPA100 present, the KAT100 Vf and Vr values are only used to 
compute the SWR due to the result of the tuning algorithm.

If the KPA100 is taken out of the equation (by physically removing the 
KPA100), then yes, the KAT100 wattmeter power output reading will be 
sent to the K2 MCU.
