How to Buy Two-Way Radios

1Look at your budget. If you want to save money and expect to use the radios over short range (less than two miles), choose FRS radios.
2Choose GMRS radios–a newer type–if you need range up to five miles.
3Apply for a Federal Communications Commission (FCC) license, which you’ll need to use a GMRS radio. You’ll need to complete FCC Forms 605 and 159 (Form 605 can be filed electronically at wireless.fcc.gov/uls/applications/).
4Purchase multiple radios from the same manufacturer. Although all FRS and GMRS radios use the same frequencies, their other features (such as so-called privacy codes) don’t always work between brands. GMRS radios share some channels with FRS radios. If you’re replacing an FRS radio, buy a GMRS unit.
5Take the range claims of 2 way radios with a grain of salt. FRS purports to reach two miles and GMRS up to seven miles, but walls, hills, trees, people and almost anything else will reduce that range.
6Look for a scanning function if you like to listen in on other people’s conversations. A scanning radio will search across its channels for activity.
7Pick units with a vibrating call feature if you need to remain quiet while you use them (during your clan’s paintball war, for instance).
