It's very easy to set up the KX3 or KX2 with a Heil Headset and no additional adaptor is needed. This short video shows how to make the menu adjustments.
Thanks for the explanation, I'm still trying to understand what is different about the Hiel headset Elecraft sells but from this video I'm comfortable that I can pick pretty much any of them.
Hi I may be missing something but I have looked on your website and I can't work out which headset terminiates in the correct plugs for the kx3. Could you point me in the right direction. Thanks Steve 2E0WSF
Sorry, I phrased my question very badly. I wanted to know which model of the Heil headset has the correct plugs for connecting to the KX3. Regards Stephen
