What is GMRS radio?

GMRS stands for General Mobile Radio Service, using the same frequency band as FRS’s Family Radio Service (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 and it’s good for 10 years. A license 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 mobile units, base stations and repeaters can use up to 50 Watts on most frequencies, they are restricted to 5 Watts when communicating on the upper FRS channels 1-7. The FRS/GMRS 467 Interstitial channels 8-14 are limited to hand-held only with a maximum of .5 Watts.

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 more importantly, 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.

What is the difference between FRS and GMRS radios?

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, you don’t need a license to operate FRS radios.

In conclusion, what are the advantages of GMRS compared to FRS?

  1. Increased power, which means longer talking range
  2. Compatibility to FRS Radios
  3. Repeater capable, increasing range even further
  4. If you receive a GMRS license, any family member, regardless of age, can operate your GMRS stations and units within the licensed system without additional licenses. Yes, husband, wife, children, siblings, grandparents, aunts, uncles, and even in-laws.
