[Elecraft] K3 PTT Button construction project

[Leigh L Klotz, Jr.]

I bought an inexpensive $15 headset for my K3, but didn't want to use VOX
because of in-shack "QRM."

For the 2007 Sweepstakes I used an MH2 in the front Mic jack as the PTT
button, but decided to try for something better. Read about how I built
it.
