[Elecraft] Parting shot

FWIW, the user manual is fine.  What you are describing, is a service manual.

Mel,

Precisely!!!
I'm trying to diagnose a K2 fault at the moment. I'm largely acting as a robot 
directed
by Don Wilhelm, thank goodness for Don&  Gary.
  
  I would be
even more at sea, out to lunch,  if I were trying to cope with a fault in the 
far more complex K3.
I've read the K3 manual carefully [fb user manual!] and I still don't have a 
clue as to circuit level function, sufficient to infer fault from malfunction.

[I did my PhD thesis on electronic fault diagnosis&  co-wrote the first
book on the subject . . .]

I'd like to see a K3 service manual, or at least a comprehensive circuit
description. Without some explanation, the downloaded schematics are pretty
worthless to somebody trying to understand the radio. In particular, the
published K3 block diagram is an exercise in obscurity. In my opinion, it's
nearly impossible for someone even to follow the receive or transmit signal
path.
