[Elecraft] KPA100 power on 20m/30m, update

[Mike Markowski]

This is a follow up to my own problem for the sake of complete Elecraft
archives.  :-)

A few weeks back I mentioned having slightly lower power on 30m.  When
the power knob was at its max, I had 97 W while all other bands were
close to 120 W.  What I forgot to mention is that on both 20 m and 30 m
I always got the HI CUR warning, though the warning threshold was set to
3.5 A.

I recalibrated the PA and then got 100+ W on 30 m.  But a subsequent
check a week or so later showed I was back down to 95 W into a dummy
load.  Not a big deal, really, but I didn't like the HI CUR message and
spoke with Gary at Elecraft about it.  He recommended changing the C80 &
C81 caps.  After doing so, I no longer get the HI CUR warning.  In
addition, I get slightly over 100 W on all bands rather than the nearly
120 W on most.  Whether that it's due to new caps or better calibration,
though, I don't know...  I posted this followup because initially it
seemed that a simple recalibration took care of the issue, but turns out
I needed new caps like the other guys who were suffering from even worse
side effects of their C80 and C81!
