What does the term "VOX" refer to in amateur radio equipment?

The term "VOX" stands for Voice Operated Transmission, which is a feature commonly found in amateur radio equipment that allows automatic activation of the transmitter when the user speaks into the microphone. This is particularly useful for hands-free operation, as it eliminates the need for the operator to manually press a button to initiate transmission. When the radio detects sound above a certain threshold, typically linked to the operator's voice, it automatically switches from receive to transmit mode, ensuring a seamless communication experience.

This technology enhances convenience for operators, especially in situations where they may need to multitask or when using hands-free setups like headsets. As a result, VOX is a valuable feature for many amateur radio enthusiasts, allowing for more fluid and efficient communication during operations.
