What Is GMRS?

The Basics

The General Mobile Radio Service (GMRS), authorized by the Federal Communications Commission (FCC), enables short to medium range communication between individuals. GMRS is an excellent addition to personal and community emergency preparedness plans. 

The General Mobile Radio Service channelizes frequencies in portions of the 462 MHz and 467 MHz UHF band. Licensed users can access 22 channels, some of which are shared with the Family Radio Service (FRS).  Channels 1-14 are FRS channels, and 15-22 are solely GMRS channels. Non-licensed users are strictly limited to the FRS channels only. 

Three of the most appealing qualities of the General Mobile Radio Service are the range, power output, and use of repeaters. 

Range: The UHF frequency band works on the line-of-site principle. Any obstructions between two radio transmitters such as hills, valleys, and buildings will block or deflect the radio signal and reduce range. 

The most important factor in determining range is antenna height. 

Power output: The maximum power output authorized by the FCC for the General Mobile Radio Service is 50 watts, which can enable great range with the right antenna system and terrain. 

Repeaters: A repeater can be thought of as a relay. It is a special radio that receives a radio signal on one frequency, and re-transmits it on another. GMRS repeaters provide greater range due to their antennas being high above obstructions, high-gain antennas, and higher power output. 

Repeater benefits

How Can GMRS Benefit You?

Support for routine and emergency communications: A backup communication system is crucial. There is no guarantee that cellular service, the internet, and the power grid will remain operational during times of crisis - disruption of these vital communication services places lives at risk. 

GMRS allows a robust way to maintain contact with friends, family, and other licensed users in the community. GMRS can also be used for daily, routine communication. 

Family licensing for a single fee: A licensing fee of $35 covers all immediate family members for a period of 10 years, regardless of age. 

Extended range with repeaters: GMRS allows integration with repeaters that greatly extend the talk range and reliability of communications. Depending on a repeater’s location, antenna system, terrain, and power output, a repeater can allow communication for 50+ miles.

A gateway to other areas of radio communication: GMRS offers a way to network with people who are licensed in other areas of radio communication, such as Amateur Radio. 

An investment for safety: Being able to communicate in real-time is crucial for organizing, responding, and mitigating hazardous and emergency situations.
