[Elecraft] K3: Right paddle key not working?

[James Sarte]

Gene et all,

I reheated the contacts on RFC4 to the point that I think I even slightly
warped the casing of the choke on one side.  No good.  No continuity at all
from any of the trace points or direct contact with the chokes leads.

Looks like RFC4 is dead and K3 #2730 will have to go back to Aptos for
repair.
