I have been wanting to use a surplus David Clark headset that I have for use with a Baofeng radio and I finally got around to doing it. Here is what I did.

I needed this to communicate at a race track. It’s working now but I plan on doing some more work to fully meet my needs.

I hope to add a PTT switch to one of the ear cups.

My wiring diagram will be posted below when I get time ………..
