I’m not sure where it was, but somewhere I saw that another ham was using an inexpensive electronic piano sustain pedal as a PTT footswitch for his radios. I’ve been using a DXE footswitch, and before that one from Heil. Both were “ok”, I guess, but they skate around and you can’t really rest your foot on it without keying the radio inadvertently sometimes.
Today this guy (amazon link) showed up, and it’s pretty great. So far for $14 I love it. We’ll see how it holds up.
