I have no idea if this Heil headset has an electret or dynamic mic. Is there a way to determine that?  I don’t want to take a chance of messing up the rig. Maybe it would show up when using the MONITOR function to listen to see how I sound?

Thanks,

Mike NJ2OM

 You can go into configure and turn the mic bias on, or off..

I think that Elecraft sends the bias voltage on the mic's audio line, so if a dynamic mic is used, then it will have voltage applied to it, which is NOT good for it!   

Some rigs have a separate bias voltage line on their multi-pin mic connector to supply bias to those mics that need it; those that don't will not have any connection to that pin on the connector.
