[SCCC] CM500 Headset

[Marty Woll]

Good question, Dennis.

The Elecraft K3 has a menu option to power the microphone, and it works
perfectly with the CM-500.  You do need to reduce the mic gain to around 25,
about half the value used with dynamic mics.  

For radios without mic power, the headset comes with a small  in-line module
that runs off a common battery to power the mic.

In an earlier thread, several of you said you were using the Yamaha CM500
headset. I see that has an electret mic. What are you using to power it?
Plucking it from your radio? Did you have to wire a special cable?
