[Elecraft] [K3] using a footswitch for PTT

[John Shadle]

That's exactly the case--and what I was thinking about doing.

I was also considering desoldering the center arm of the switch and bending
it up, to connect it to the top arm of the switch; however, being that the
center part is plastic, I'm not sure it would survive this process.
