[Elecraft] Key in K3 not working

[Chuck Mabbott]

Have you tried a different key?

While slim chance it is that simple might be worth a try before you 
tear into the radio?

Here's what I did now to rule out the actual K3 jack:

I took the rear bottom panel off.  I checked continuity with a plug
connected to the socket.  I touched ground on the plug and G on the RF main
board and that passed.  Did the same with ring R, and tip T, and all
passed.  So there doesn't appear to be anything wrong with the contacts
inside the jack itself.

Strange...
