How to Use Walkie-Talkie Radio
Using a two-way walkie-talkie radio is very simple.
Each hand-held device comes with a built-in speaker and microphone as well as other electronic components that enable it to both transmit and receive signals or voice data at different radio frequencies.
Certain electronic components inside the walkie-talkie convert audio or voice data received by the microphone to radio frequency signals before it is sent by the transmitter over a specific channel. The process is called transmission.
Oppositely, the same electronic components in the walkie-talkie are also capable of converting radio frequency signals and turn them into voice or audio data as it is fed to the speaker. This process is called reception or receiving.
Other Features and Ease of Use
The range of available radio frequencies for the walkie-talkie is called bandwidth. Selecting a specific channel for the radio frequency band is obtained through a dial.
The early makes of walkie-talkies also feature an antenna to the device to boost signal transmission and reception. The longer the antenna of the walkie-talkie, the stronger its transmission and reception capabilities become.
But because of advancement in technologies, which gave certain electronic components the stronger capability to process signal transmission and reception, the longer antenna has become a thing of the past.
To start a conversation using a walkie-talkie, it is important first for the communicating parties to agree on a specific radio frequency or channel.
Communication begins when one party attempts to make a voice transmission by pressing the ‘Talk’ button on the device. For as long as the ‘Talk’ button is pressed, the transmitting party would not be able to receive any signal or voice data from the other party. Releasing the ‘Talk’ button would allow the walkie-talkie to receive signal and voice data from the other end and two-way communication is completed.
