[Elecraft] K2: Power displayed when in Tune mode

First, ensure you are tuning into a 50 ohm dummy load.  The K2 power
calculations are based on the assumption that there is exactly a 50 ohm
load.  The initial dummy loads I was using, once I checked them with an
analyzer, were off by a bit.  I found one showing 50.1, and used that
and the rig responded much more as expected.

That being said, the K2 isn't the most stable from a power output
perspective.  As I have been using mine a bit, and have the amp and the
tuner, I set it to a power level a go.  Not often watching it as I make
changes.

As memory serves, there is also some concerns, as far as how the rig is
brought into the continuous power mode for measurements.  Might want to
take a look at the archives.
