[Elecraft] Yamaha CM500 Headset and Heil Adaptor

[Bruce & Gab]

Recently purchased a Yamaha CM500 headset with a Heil AD-1-K headset adaptor
for Kenwood (the red one).  I love the headset, much cheaper than the Heil
and performs about the same, IMHO.

The only way I managed to get the mic to work was through the rear jack
(yes, the mic was selected to front panel).

I did read in previous threads referring to mono and stereo mic connection.


Do I need to replace the stereo mic connector on the headset with a mono?

Is there a trick with the adaptor or am I messing up the set-up?
