Use an Ohm meter and see if pin of the Foster plug is connected
to the center pin of the 3.5mm jack on the AD1-K (DC connection).
It is entirely possible that the adapter has a blocking capacitor
as the AD1-K was designed for use with Heil's dynamic microphones
which do not want DC on the mic element.

Does anyone have any ideas why my Yamaha CM-500 microphone won't work
when
plugged into the front of the K3. I am using the Kenwood AD1K adapter
and I
have the firmware set to select the front panel, low gain, with bias on
(FP.L bIAS). The CM-500 headphones are plugged into the Phones jack
on the
front of the K3 and work fine. The CM-500 mic plug (grey) is plugged
into
the corresponding jack on the AD1K. When I press my footswitch, the K3
goes into transmit but there is no audio when I speak into the CM-500's
microphone. I have tried the footswitch plugged in both on the back
of the
K3 and into the AD1K footswitch jack and it works fine (puts the K3 into
transit) in both cases.
When plugged into the rear Phone and Mic jacks on the K3, the CM-500
works
like it should. In that case I have the firmware set to RP.L bIAS.and
both
the CM-500 microphone and headphones work fine, so I'm quite sure the
CM-500
is not the culprit.
It almost seems like the AD1K is the problem.
This must be something simple, but I am stuck. Any suggestions much
appreciated.
Thanks
