[Elecraft] Info 080 and KPA100

[Joe Hetrick]

Greetings folks,

	If I may interrupt the K3 threads for just a moment...

My K2 SN 4912 developed a fault sometime between last evening and  
this evening!  Upon jumping to the shack to
have a few relaxing QSO's before bed I was greeted by an INFO 080.  I  
figured I'd start by checking pins of RFU1 as in the
manual and pulled the KPA.  I fired it up without the KPA, and,  
problem disappears.

Casual inspection of the KPA shows no fault, searching the list turns  
up no clues, and finally the KPA manual refers INFO 080 back to the  
K2 manual.

If I had to guess, I'd say auxbus short.

With only the KPA connected (nothing external to the AUX RS232) fault  
remains.  Where should I start digging in the KPA?

73,

Joe, KC0VKN
