Two-way radios, also known as walkie-talkies or handheld transceivers, are communication devices that allow users to communicate with each other over short distances using radio waves. They are portable and wireless, making them useful in various scenarios such as outdoor activities, construction sites, public safety operations, and more. Two-way radios operate on specific radio frequencies and can transmit and receive voice messages in real time. They typically have a “push-to-talk” (PTT) button that users press when they want to transmit a message and release when they want to listen to messages from others. They are commonly used for team communication and coordination where cell phone coverage might be limited or unreliable.
