[Elecraft] Yamaha CM500/PPT Headset

[Ron D'Eau Claire]

A monaural (two-conductor) 3.5 mm mic plug will work with the KX3. That's
how the ProSet is used with it. 

One disables the PTT function (otherwise plugging in the mono plug will put
the KX3 in xmit). 

You can use VOX or tap the XMIT switch on the KX3 to switch between tx and
rx.

Actually it does not matter.  No adapter is included with the K3 or 
KX3.  The KX3 will include a mic plug you can wire yourself.  It is a 
3.5mm 4 conductor plug.  There is a menu item to enable or disable the 
up/dn button signals provided by the MH3 mic.

I connected a standard 3 conductor audio cable that breaks down to two 
RCA connectors and use that to interface my CM500 and a PTT switch.
