Dave,
Lyle confirmed that the mic jack in the K3 is wired for Elecraft - just
like the K2 with all pins of the mic configuration header plugged
straight across.
That wiring is not for all Kenwood mics. Kenwood mics with an internal
preamp expect to have voltage on pin 5, and the Elecraft has voltage on
pin 6, but all Kenwood mics without an internal preamp (not connecting
to a voltage pin) will work.
Elecraft is again offering the MH2 mic with the advent of the K3 to
address the need for an Elecraft mic.
73,
Don W3FPR

Shouldn't Elecraft decide on a standard microphone connection and stick
with it? I suspect they probably have as the K3 appears to be "Kenwood 8
pin" with no alternatives, if I remember correctly an earlier post from
Eric.
If anyone building their K2 wishes to use a Kenwood microphone, then
computer 2 pin "jumper" connections link the adjacent pins which avoids
soldering wires on the pins.
Here in the UK, Waters and Stanton (http://www.wsplc.com/) list the
Kenwood MC-43S fist microphone at 19.95 GBP, which appears to be very
good value. I use one on my K2 and it works fine.

K1, K2 and K3 on order.
