[Elecraft] Adding KPA100 to KAT100-2

[Dave Van Wallaghen]

Hey Tom,
If I'm reading what you wrote correctly, it looks like you have it connected
correctly. Here is a link to Lyle Johnson's website if you don't have it
already: http://www.kk7p.com/k2kpa100.html
Go near the bottom of the page. He has some nice pictures of what it all
looks like connected. 

If I remember right, I actually plugged (read muscled) the Aux RF connector
in reverse. Not sure if that could cause what you're seeing. Also not sure
what tuning into an open load would do either.

I'm sure that many on the list brighter than me will give you some good
advice.

Good luck & 73,
Dave W8FGU
