[Elecraft] KAT100 woes... Time to 'fess up...

Tom:

A very nice read.  Confession is good for the soul.  I must confess I was 
building a KPA100/KAT100 in an EC2 enclosure for a fellow not long ago and 
when trying to calibrate the output meter I never could get it the right 
indications on the wattmeter and the max I could get out on my KPA100 
looking at an external meter was 20 watts.  I replaced a couple of chips and 
still no joy.  I finally realized that I was using the Tune button on the K2 
and had a KAT100 connected also.  The firmware was doing its job in reducing 
the power to 20 watts for tune up.  I connected a straight key and keyed the 
unit and adjusted my power to 100 watts and then set the K2 display 
correctly...LOL  One other thing was that no matter where I set the RF Power 
control it always put out 20 watts just like it was supposed to do. 
Sometimes and recently more often than I care to admit, the machines are 
smarter than I am....LOL
