[Elecraft] Key in K3 not working

[James Sarte]

Hi Chuck,

I didn't have another paddle to try, but all of my testing has shown that
choke RFC4 was to blame.  It's wide open with no continuity.  I have since
bypassed the choke with a piece of wire and now everything works properly.
I'm still waiting to hear back from Dale whether or not he will send me a
replacement choke, or if I should just send the K3 back to Aptos.

Here's a pic of my "mod"
