General Mobile Radio Service Frequency Table
This table is the frequency chart for the legal General Mobile Radio Service. There are 22 frequencies as opposed to designated channels on some services; 7 are shared with the FRS. While they are shared frequencies, GMRS can have significantly more power legally than the FRS units. You may NOT transmit on the FRS frequencies with a GMRS radio (or a combination radio) without a GMRS required license! GMRS also uses split and shift operations within the frequency range of 462 to 467 megahertz (MHz). GMRS, as it is called, uses certified commercial grade, UHF-FM radios identical to those used by public safety agencies, businesses, and other governmental, commercial and industrial licensees in the Private Land Mobile Radio Services. Expect a communication range of 1 to 5 miles, generally line of sight; significantly less if not LOS, and perhaps more with a good, high antenna. License documents and privileges are issued by and governed by the Federal Communications Commission (FCC). The current regulations provide your authority to operate a GMRS unit in places where the FCC regulates radiocommunications, as long as you use only an unmodified FCC certificated GMRS unit. An FCC certificated unit has an identifying label placed on it by the manufacturer. You may operate your GMRS unit within the territorial limits of the fifty United States, the District of Columbia, and the Caribbean and Pacific Insular areas ("U.S."). You may also operate your GMRS on or over any other area of the world, except within the territorial limits of areas where radio communications are regulated by another agency of the U.S. or within the territorial limits of any foreign government. You may also be permitted to use your GMRS unit in Canada subject to the rules of Industry Canada; other countries may also allow GMRS frequency use but it is your responsibility to verify that prior to use.
The GMRS, along with FRS, was adopted by the FCC on May 15, 1996; this page was created the same day. GMRS uses narrowband FM (NBFM), normally with a maximum effective radiated power of 0.5 watt (500 milliwatts); there are exceptions. GMRS is intended for hand-held, short-range local mobile communications, although some exceptions are permitted; certain kinds of brief and burst data transmissions from unique GMRS units specifically certified for the operations of data capture. Base stations and frequency repeaters may be licensed for communications with the mobile units and my be allowed up to fifty watts of power; some mobile units are licensed for 1 to 4 watts of power. Your license determines the power that you may use and the antenna height you may have. In UHF communications, antenna height is a critical factor in operating distance.
