[Elecraft] K3 Intermittent mic connector

[Don Wilhelm]

Mike,

It sounds like a bad solder connection somewhere.
Before you dig into the K3, try the mic directly on the K3.  If all is 
OK, then investigate the connector for the Duo to K3 cable.
If it persists with the mic connected directly to the K3, then it may be 
a K3 problem.

Right now, there are too many variables - the Duo to K3 cable, the PR781 
mic connector, the DUO itself, and the K3 - all can be suspect.  
Eliminating the Duo will reduce the variables to 2 - the PR781 mic plug 
and/or the K3.

73,
Don W3FPR
