[Elecraft] K3 Front Panel mic audio issues with Microham MicroKeyer II

[Mike Fatchett W0MU]

It would have been nice to know before I put it all together............

I guess it affects mics that don't require bias too.

I will do the mod and let everyone know....After the weekend contest.

Mike,

If you have a serial no between 660 & 782 you need to do the mod for
grounding the front panel mike connector.
