[Elecraft] K2 power out increase with higher SWR

[Brett gazdzinski]

If you tune the antenna tuner each way, you should
see the power go both up and down from say 5 watts.

If I tune the heathkit antenna tuners roller inductor
 (before adding the built in tuner to the K2), one way
would increase the K2 power display, the other way would lower it.

Since the K2 only reads voltage, a higher power would be higher
voltage, not a good thing for the caps and other parts in the output
section....
