Two-way radios work by using radio waves to transmit and receive audio signals between two or more devices. When one user speaks into the radio, the device converts the sound into radio waves and transmits them to the other radios within range. The receiving radios then pick up the radio waves and convert them back into sound, allowing the users to communicate with each other in real time. This communication is possible because the radios are set to operate on the same frequency, allowing them to send and receive signals to each other. **
