Thanks to its ability to use repeaters, GMRS can be used for long-distance communication.
Antennas on GMRS gear can be removed, enabling a handheld to be used with a car mount or stationary antenna. See Table 1-1 for a complete list of FRS and GMRS frequencies. Stations and repeaters can only transmit on the lower “462” frequencies, while handhelds can transmit on any GMRS frequency. Stations that transmit on repeater channels can transmit at a maximum of 50 Watts. When communicating on FRS channels, fixed-base stations are restricted to 5 Watts, even though they can use up to 15 Watts on most frequencies. GMRS handhelds are capable of putting out up to 5 Watts of power, although 4-Watt units are more common.
#GMRS REPEATER FREQUENCIES LICENSE#
The cost of a personal license as of this writing is $75 and can be obtained online at. GMRS stands for General Mobile Radio Service, also known as “Class A Citizens Band.” This service is covered by FCC Part 95, but requires a license to operate.

The full list of FRS and GMRS frequencies can be found in Table 1-1. You should use channels 8 through 14 if you only want to talk to other FRS radios to avoid possible interference with low band GMRS users. GMRS stations can communicate with FRS radios through channels 1 through 7 which overlap with GMRS. Antennas and amplifiers cannot be legally added to FRS radios because they come with fixed antennas. FRS radios typically have a range of two miles. GMRS and FRS share some channels, but FRS radios can only output 500mW at most. It operates between 462 and 467 MHz, and is sometimes referred to as the “UHF Citizens Band.” This is not an 802.11 radio, but is governed by FCC Part 95, Personal Radio Services. In 1996, the FCC approved Family Radio Service for unlicensed use. Even though they often sit right next to each other on the shelf and are packaged similarly, these two types of radios are very different when it comes to capabilities and operating rules. The devices have a range of a few miles, are powered by AA batteries or a rechargeable battery pack, and are surprisingly simple and easy to use.įRS and GMRS are the technologies behind these radios. There have been several companies in recent years that have been developing “high-power” radios marketed as family or recreation communication devices sold in department stores as impulse buys.
