VOX in two way radios

When searching online for a suitable walkie talkie, you may have come across some that have VOX capabilities and wondered what VOX stands for.

You will more than likely see this feature listed on many popular radios, especially the Motorola TLKR range, or noticed some radios allow the use of VOX accessories.

Simply put, VOX stands for voice-operated exchanged or more commonly known as voice activated transmission.

Every two-way radio or walkie talkie has the use of a PTT (push to talk) button which allows you to transmit audio to other users. However, certain models have the VOX feature which means they can be used hands free. With the VOX feature switched on, the radio microphone is always listening. This means it will automatically start and end a transmission once it hears your voice.

This feature will take away the burden of pushing the PTT button every time you wish you communicate.

VOX Sound Activation
Allow the VOX feature might sound like the perfect solution; it can be a burden for yourself and other users. The VOX feature not only picks up your voice, but also background noise, so if the radios are being used in a noisy environment, the microphone will always be on.

The majority of radios are VOX compatible, however only a few will come with a switch that allows you to switch between the PTT button or VOX. So, you will need to double check the feature before purchasing to ensure they’ll work well within your environment.

VOX Accessories
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.


Which walkie talkies have VOX capabilities?
On today’s current market, most mid-range and high-end radios come with VOX. You may think that two-way radios with this feature are quite expensive, however that’s certainly not the case. Take a look at the T92 within the Motorola TLKR range, it has an IP67 rating, is fully waterproof, and floats when dropped in water. It is the perfect cost-effective option for use in a challenging environment.
