Elecraft and Kenwood reverse the pin used for +8V that powers
the DTMF encoder. You will need to move the wire on pin 5 of
the Kenwood Foster plug to pin 6 to get the +8V from K3/K3s.
The same is true if you want to use a Kenwood desk mic with
built-in preamp or active equalizer (e.g., MC-60A, MC-80, MC-85,
etc.) with the preamp or eq.

David,
Are you certain the Kenwood mic is electret? Most are dynamic. Make
certain the mic plug is wired for standard Kenwood pinout for HF mics,
Some made for VHF rigs may be different.

Currently, use of a DTMF-equipped microphone or generating the tones
with an attached device. The K3 does not generate DTMF tones,although
it could in a future firmware enhancement.

Well, in the absence of the long awaited DTMF software enhancement for
the K3 I have at last bought myself a Kenwood microphone, fitted with
an 8-pin plug that mates with the K3. But I have had no success in
getting the DTMF feature to work :-(
As the Kenwood mic is electret I have switched bias on with MIC SEL
although, surprisingly, the microphone seems to work equally well with
it switched off!
Does anyone know how to get the Kenwood DTMF mic to work with the K3?
