[Elecraft] Rear Panel Mic help ple

[Don Wilhelm]

Ed,

I would instead suggest that you open the TRS plug and connect the ring 
to the shell there.  The ring is not connected in the K3, but a stereo 
jack is used.  If the Flex uses a mono jack, the jack would have shorted 
between the ring and sleeve and the mic would work.

73,
