How does a GMRS radio work?

It's an FM two-way walkie talkie. The GMRS (General Mobile Radio Service) was created as a replacement for the old Citizen's Band radio system, and operates on a different frequency spectrum set aside specifically for that service.

The radios are generally limited to 2 watts of transmit power, and are FM to limit the maximum distance over average terrian of around 2 to 5 miles.
