A two-way radio is a radio that can both transmit and receive, unlike a broadcast receiver which only receives content. A two-way radio allows the operator to have a conversation with other similar radios operating on the same radio frequency (channel). Two-Way radios are a critical part of your emergency preparedness planning, providing a critical line of communication in severe weather or remote areas. More than a traditional weather radio, these radios give your family a reliable means of two-way communication when other options fail. In this article, we will explore how two-way radios work, along with their various features.
Motorola Talkabout® Two-Way Radios are designed to provide affordable and dependable communication, ideal for the outdoor enthusiast, active families or an emergency preparedness kit. These radios work in remote areas, are rugged and convenient to use are provide instant access without using up your cell phone minutes. See our Motorola Catalog.
How Does a Two-Way Radio Work?
Two-way radio systems usually operate in a half-duplex mode; that is, the operator can talk, or listen, but not at the same time. A push-to-talk or press-to-transmit (PTT) button activates the transmitter; when it is released, the receiver is active.
The two most common two-way radio systems operate in the VHF and UHF parts of the radio spectrum. Because this part of the spectrum is heavily used for broadcasting and multiple competing uses, spectrum management has become an important.
The ultimate communication tool for the serious outdoor enthusiast, the rugged and lightweight Motorola Talkabout® MR350R is built to handle any challenge. The MR350R features a range of up to 35 miles, and extra-large buttons for ease of operation (even with gloves on).
