i saw in a further post back that someone said thay had a foot pedal that they push to talk instead of having to pick up a mic etc. Is this true? Is this what dispatch consules use instead of mics generally?
Foot switches are pretty common, it frees both hands for doing other things; typing, mouse/track ball use, etc. VOX (voice operated transmit) may or may not be available, but generally not used in noisy dispatch type environments. Hams make use of VOX a lot on HF SSB, but not so much on HF AM or VHF/UHF FM.
Yup, foot switches are used in lots of things, machinery especially and are easily adapted. I once salvaged one from an old sewing machine, had to remove the speed control rheostat of course. Now why don't we use VOX for AM or FM? Do you think continual carrier dropouts could lead to a frustrating QSO? Oh, I can just imagine CBers adapting wa-wa, sustain and swell pedals for those "special effects", they already sound like they're using fuzz. (;->)
