[Elecraft] [KX3] Push-To-Talk Mic Adapter

[Mark Tannert]

I recently purchased an inexpensive condenser microphone for the KX3. While
it's very functional for my needs, I was frustrated with the need to
manually push the XMIT button every time I wanted TX. I can't run VOX
because I have too many interruptions.

So I built a little PTT adapter for my Heil foot switch. This adapter can
probably work for any number of switches for PTT, so I thought I'd share
the design and implementation.

Hopefully no one minds my use of a little bandwidth to share this.

Cheers!
