How Two-Way Radios Work: A Beginner’s Guide
A two-way radio, often called a walkie-talkie, lets you talk to other people without a phone plan or a cell tower. You pick a channel, press a button, speak, and anyone else on that same channel can hear you. When you let go of the button, you listen. That is the whole idea.
