-Front mic socket not compatible with any other mfg. that I can find.
Actually, it is!.. and it is well documented.. the front panel mic connector
conforms to the Kenwood pin-out. I am using a Kenwood MC-60 on my K3 (#269)
with no modifications and no problems.

As Don has already stated the Kenwood standard wants power (+5V ~ +8V)
on pin-5, whereas the K3 Elecraft standard has FUNC on pin-5 and what
Elecraft calls "bias" on pin-6.
See < http://elecraft.com/K3/K3FAQ.1.jpg > for the K3 pin-out and
< http://homepage.ntlworld.com/rg4wpw/kwood.jpg > for the Kenwood pin-out.
If this < http://homepage.ntlworld.com/rg4wpw/kwoodcompat.pdf > partial
Kenwood microphone compatibility table is correct, one can rule out plug-
compatible interoperability of many Kenwood mics with the K3, based solely
on the fact that they have an Electret element.
From the available information, it appears that your MC-60 and just two
other Kenwood mics (the MC-42 and MC-43) are the only 8-pin round connector
models that will work with the K3 without some sort of adaptor to swap pins
5 and 6.
My conclusions are based on available information. There may be addi-
tional Kenwood mics that will simply plug in and work properly with the K3.

K3 S/N TBD
P.S. I don't see this issue as a good reason to sell the K3!
