Thanks all for your suggestions how to use the old Heil headset with an HC-4 element.
Unfortunately, I couldn't make it work and sound good with the KX3.

You have to crank up the mic gain very high and it sounds like you're in a barrel!

It's an old headset but I don't want to throw it away, so I'll probably replace the
HC-4 element with an electret.

Before plugging in the mic from Menu set mic buttons to OFF. See the manual 
about this. Also be sure Bias is OFF.

You will need to tap the Transmit button to speak and again to stop.

Or use VOX, see manual to set this up.

Go have fun!

Hi all,

I want to use an older Heil headset, with an HC-4 element, with my KX3.

Despite having tried different settings for the microphone, I can't make it 
work.
Your ideas and suggestions would be much appreciated. Thanks!
