What is VOX, and how does it work?

VOX stands for “Voice Operated Exchange”. To put it in simple terms, that just means voice-activated transmission. With this mode switched on, the two-way radio is always listening out for human speech. It does this by detecting tiny changes in the air pressure. It then automatically starts transmitting when someone starts talking. Once you stop, the handset will stop transmitting, so that you can hear the other person’s reply.
