[Elecraft] CM-500

Bill,

I am not certain how your other radios determine whether the microphone 
needs bias or not.
Yes, if you are using Icom with Icom mics, those need bias.
If you are using Kenwood or Yaesu, they do not supply bias.

The bias or not question depends on the microphone used.  Elecraft 
allows you to use many different microphones, but you must choose 
between bias on or off as a result.  Dynamic mics should not have bias 
applied.
