What is vox on Twoway radio?

Answer 1

" VOX " is a catchy term that means "voice control".

Any voice communication system can be equipped with VOX so that it's shut off

when you're not speaking, and it automatically turns itself on when you start

talking. On a 2-way radio system, that relieves the user of the onerous burden

of pushing the microphone button with his thumb when he wants to transmit.

It does have real value, however, if he's wearing a headset/boom and not

using his hands at all for the radio. It's also used on aircraft radio, so that the

pilot doesn't have to dedicate the use of a hand just to talk on the radio.
