[Elecraft] K3: Right paddle key not working?

[Gene Langendorff]

I had the same symptom on my year old newly completed K3 kit a few months
ago (S/N 3172).  With Gary's guidance found the trouble to be one of the
surface mount chokes (RFC3 or RFC4) between the paddles jack (J12) and the
board needed resoldering.  Check for continuity with your ohmmeter and you
will probably find one of them not connected.  Carefully resolder each end
while applying downward pressure, one end at a time, and it should work.

  James,

Based on your other posts to the reflector where you checked continuity 
inside the K3, I would suggest a new download of the firmware, save your 
configuration, then do an EE INIT.  Install the firmware via K3 Utility, 
restore your configuration and see if anything changes. If that fails to 
correct it, an email to K3support at elecraft.com is in order.

Why do these things always happen on the weekend??
