- How they work
On every walkie talkie device out there, there is a button, and the button is pressed when the individual wants to talk. This transmits the sound. If you want to listen to what the other person is saying then you don't press the button and you listen to what is being said on the other end. While you have that switch on, only you can say something and anybody tuned into the frequency will be able to hear it. Walkie talkies, usually are small handsets that you can use when you're traveling, and that's where the name 'walkie talkie' comes from. They're basic devices but can be useful in some situations.
