VOX is a feature commonly found in most higher-end consumer two-way radios. You'll see this feature listed on many of the most retevis popular model. But what is VOX on a two-way radio, and how does this feature work? Not to worry- read on, and all will be revealed!
Virtually all two-way radios have a push-to-talk, or PTT button, to allow you to start transmitting. However, models with VOX can also be used hands-free. VOX stands for "voice-operated exchanged", and is sometimes also referred to as "voice activated transmission". With VOX switched on, the microphone is always listening out for your voice. When it detects you are speaking, it will then automatically start broadcasting.
When VOX is activated, your radio automatically turns itself on when the user starts talking, and shuts off when there is no sound. On 2-way radios, this feature saves you having to push the microphone button every time you want to start transmitting.
VOX is sound activated; not just voice activated. This means that, for instance, if you're using your retevis RT22 in a very loud setting, it may pick up background noise and will be in constant transmit mode.
A lot of radio handsets are VOX compatible. Some come with a toggle switch to let you change between PTT and VOX usage. To stop unwanted transmissions, manufactures use sensitivity settings to assist with the activation process. This means the switch will only kick in when it detects sound over a certain decibel level.
Even though the radios themselves have VOX, there is also a number of earpieces available that will make hands-free communication much easier. Because the earpiece microphone will be closer to your mouth, it will pick up the sound of your voice better than if your radio was strapped to your belt.
If you are going to be in a noisy environment, this is something we would suggest you use so you do not miss out on any important transmissions. Earpieces often help to cancel out more background noise, which will help the microphone pick up your voice.
