[Elecraft] KPA1500 power per frequency bin

[K8TE]

I am right there with Hank, and probably a lot of others.  It's worse when
one has an external antenna switch which the KPA1500 can't sense so it's
necessary to provide low power from the K3 to avoid a fault because of the
different antenna and the tuner can provide the appropriate (already
trained) match.  Also, switching between ANT1 and ANT2 with different
conjugate matches often requires different power levels from the K3 (or
other radios).

So, for operator "convenience" I find it necessary to set the K3 power level
at the lower point to avoid faults.  Sadly, there is now way for the KPA1500
to tell the K3 (or K4) what's going on and therefore what to do.  I'm
attempting to become smarter with an Arduino and, hopefully, figure out how
to automate this.  It requires a look-up table to determine frequency,
antenna, tuning solution, for setting the exciter drive level.  So far, I
can spell Arduino correctly four out of five times.  That is progress! 
Next, I will plug it in.

BTW, if one's antennas demonstrate little to no reactance and a 50 Ohm
match, this is not an issue.  That only happens in the movies and on TV
(Last Man Standing? who needs a K-Line, obviously).
