[Elecraft] KX3: CM500 best price/use with

[Edward R Cole]

Guess finally time that I consider a Yamaha CM500.  Considering 
operating in remote open areas with my KX3-2M as IF radio for mw, it 
will be handy to have the headset/boom mic combo.

I note the CM500 comes with separate mic and headset connectors while 
the KX3 has that four ring mic connector.  I wonder if a conversion 
cable has been made or offered?  I will probably be plugging the boom 
mic into a sequencer box which will delay activation of PTT while 
passing on mic audio.  Still will need a cable to plug into the KX3 
mic jack.  I assume the headset connector is compatible with KX3?

I can make a cable if the four-ring plug is available.

How are most handling mic PTT with this headset?  One add shows a 
black box with receptacle and cord with stereo plug (nothing stated 
in add what this is but wonder if its use is PTT?).  Best price I am 
seeing is $59.95 free shipping.  Anyone have a cheaper source?

I could use while mobile if local laws permit headsets.  Currently 
just using internal speaker in my truck.  Also thoughts of connecting 
truck Sync with KX3 headset out but haven't studied that yet.  For my 
poor hearing the headset is better solution.
