In VOX (Voice-Operated Transmission) the ra-
dio is keyed when a voice signal is present on
the audio or line interface. If VOX is on, the op-
erator can switch to transmit mode (TX) by
simply talking, and when he stops talking the
radio automatically returns to receive mode
(RX). The transmitter is keyed as long as a
voice signal is present. When the voice stops
the radio will return to receive mode (RX) only
after the holdtime has elapsed.
