[Elecraft] Power Readout Discrepency

[Don Wilhelm]

Parker and all,

I trust you are not confusing the "power requested" indication that is
displayed when you turn the POWER knob with the actual power output.  The
actual power output may fall quite short of the requested power because of a
number of things - including the actual load impedance - the RF detector
arrangement in the base K2 is quite unsophisticated and great accuracy
should not be expected from it.

If you have installed one of the Elecraft automatic tuners, the story is
quite different again because the tuners include a real wattmeter (which you
can calibrate) rather than the simple RF detector included in the base K2.
