[Elecraft] K2 KPA100 tests

[Don Wilhelm]

  Mike,

How old is this KPA100(does it have red toroid cores or blue ones), and 
do you have the KDSP2 installed?  These may seem like unrelated 
questions, but actually they are not.  A looong time ago (with the older 
KPA100 T/R switch design) there was a problem with "click on unmute" 
when the KDSP2 also was installed.  The new T/R switch design corrected it.

OK on your wattmeter - if you used a "Larry" calibrated LP100 to set the 
KPA100 wattmeter, I think it is set right.  The LP-100 is one of the few 
wattmeters I trust.
