[Elecraft] [K2] Ooof.. Update

[Brian Denley]

Don was right!  I had taken the SSB adaptor out and that (without jumpers) 
rendered the K2 non-functional.  Putting the KSB2 back in and adding the 
pin1 to pin 6 jumper at J12 (as Don suggested) brought my K2 back to life! 
Now I still have to figure out what is wrong with my KNB2...
Thanks again Don!
