Everything You Want to Know about GMRS Radio

What is GMRS radio?

Known as “Class A Citizens Band" while renamed by FCC in 1987, GMRS stands for General Mobile Radio Service, using the same frequency band as FRS's (462-467 MHz). The difference is that GMRS radios have designated channels within those frequencies that aren't available to FRS radios. Its use is covered by FCC Part 95, but requires a license to operate. According to the latest FCC rules, a personal GMRS license costs $35 (The new $35 GMRS and Amateur license application fees go into effect April 19, 2022!) and can be obtained online at

How powerful is GMRS radio?

Handheld GMRS units can put out up to 5 Watts of power, although 4-Watt handhelds are more common. While fixed-base stations can use up to 50 Watts on most frequencies, they are restricted to 5 Watts when communicating on the FRS channels. Repeater stations are allowed and can transmit as high as 50 Watts. Both fixed-base stations and repeaters can only transmit on the lower “462” frequencies, while handhelds can operate on any GMRS frequency.
That means that a GMRS radio can have all the same capabilities as an FRS radio in addition to special channels that FRS can’t access, and the option to extend the range of the product.

GMRS gear can include removable antennas, making it simple to use a handheld with a car mount or stationary antenna. Combined with the ability to use repeaters, GMRS can be used to communicate over considerable distances. If you’re looking for power and range with GMRS, check out Radioddity's best GMRS radios.

What is the difference betweeb FRS and GMRS radios?

Referred to as "UHF Citizens Band", FRS stands for Family Radio Service. After May 18, 2017, FRS radios are limited to 2 Watts on channel 1-7 and channels 15–22. All 22 channels are shared with the GMRS radios. FRS radios come with fixed antennas, and cannot be legally modified to accommodate antennas or amplifiers. Different from GMRS, yon don't need a license to operate FRS radios.

    Nice run down Jackson. I already have my GMRS license but this is excellent information for people that do not have one yet and are interested in getting into using GMRS radios.

    There is a mis-statement on GMRS. You only need a license when operating more than 2 watts on GMRS or when using a repeater. Also base or mobile units can transmit up to 50 watts max, not the 15 watts you listed.
