Tim,
You can use many headsets and microphones with the KX3 - *IF* you are
willing to build an adapter.
I have my homebrew adapter for the CM500 headset that works just fine,
but if you are not able/willing to build your own adapter, order the
Elecraft MH3 microphone - it works just fine.
Computer type microphones and headsets can be made to work, but because
the tip and ring are connected together, there is some special
considerations to be had when choosing the bias - they work OK with bias
turned off, but then will be using the source for digital voltage in the
K3 to bias the microphone which can cause noise in the signal. While it
will work, a proper adapter will provide better quality results. That
is why I built the adapter for my CM500.

I have several microphones on hand and wondering if any will work with my soon
to be order KX3.
My preference is a Heil Pro-Set Plus which has two crystal elements and a phase
reverse switch. By far the most comfortable headset I have ever use. Can I
use these with an appropriate adapter?
Then I have a Yaesu HT speaker mic with the correct 4 conductor connector used
with a VX-5.
Then I have a headset with the same connector which I used with a HP netbook.
Cheep but sufficient.
Will any of these work, or should I just order the Elecraft hand mike?
