[Elecraft] K2 KPA100 tests

[Don Wilhelm]

  Mike,

The fact that you have no HiCur warnings working onto a known good dummy 
load says that the problem is somewhere in your antenna system.

On the "chirp issue", I have no immediate answers.  Normally that does 
not occur with the new T/R switch design (blue toroids).
If you had the red core toroids, I would have said the you should try 
installing KPA100UPKT, but you already have that installed, so I have no 
guesses for the cause.

I would suggest a note to support at elecraft.com to see if anyone else has 
an idea about the "chirp".

73,
Don W3FPR
