Greetings All, My K3/10F now K3/100 plus mostly loaded has a problem.
The mic connector has to be pressed down a bit to get PTT when using
the K3 on SSB. I use a Heil PR781 mic that goes through a Rigblaster Duo.
The connector to the K3 comes from the Duo and is never changed or
fooled with.
First thing I'd do is eliminate all but the mic, cable and K3. If problem
persists check plug on cable. Then at mic end. Finally check other items one
at a time.

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
I had this problem several months ago. It turns out the mic connector ground
(both mic and PTT) goes thru a 0 ohm surface mount resistor (at one time this
was a choke, I believe). I bridged this component and the problem went away.
I believe the board flexes too much
when the mic is plugged
