Understanding VOX Technology
What is VOX on a walkie talkie stands for Voice Operated eXchange or Voice Activated Transmission. This feature allows your radio to automatically transmit when it detects your voice, eliminating the need to press and hold the push-to-talk (PTT) button during conversation.
The Science Behind VOX
VOX technology works through sophisticated audio detection:
- Built-in microphones monitor sound levels
- Preset sensitivity thresholds trigger transmission
- Digital processing filters out background noise
- Automatic timing controls when transmission stops
