GMRS, or the General Mobile Radio Service band is part of the PRS, or Personal Radio Service bands, as outlined by 47 CFR Part 95E (formerly Part 95A) of the FCC (Federal Communications Commission), which regulates and makes rules for the use of all RF (Radio Frequency) radio spectrum in the United States. The band is usable for personal or business two-way radio communications with up to 50 Watts of power (5 Watts on some channels and 0.5 Watts on some other channels shared with the FRS channels – see chart below), and GMRS radios like the exclusive BetterSafeRadio co-designed Wouxun KG-UV9GX GMRS Two-Way Radio & SHTF Scanner are used by individual preppers, families, businesses, Neighborhood Watch groups, CERT, REACT, Guardian Angels, and other organizations, and is often used for recreation, sports and everyday family and business communications.
The GMRS band consists of 30 GMRS frequencies, which after recent FCC revisions of the PRS rules, now overlap on 22 channels with the FRS (Family Radio Service) band (with a revised band plan as of September 2017). Transmitting on GMRS channels does require a “no-test” license, which can be easily obtained online by any US citizen 18 years of age or older. Here’s a great tutorial on how to get a GMRS license from the FCC. Although there have been suggestions from some users to remove the licensing requirement from the GMRS band, there was no change when the FCC recently revised the PRS rules.
GMRS allows analog FM voice operation, and digital positional and text messaging with strict limitations. Digital voice modes such as DMR, P25, D-STAR, and System Fusion (C4FM) are not allowed on the GMRS band, including the repeater splits. GMRS offers several advantages over CB radio and has all but replaced it for many uses.
A GMRS license is currently $35, lasts for 10 years, is shared by you and your immediate family, and with a simple online user registration (do this first to get an FRN (FCC Registration Number), then log in) and license application, is typically granted within just a few days (or less).

FRS is not allowed on the 467MHz GMRS Repeater inputs on chs. 15-22, but is now allowed on the 462MHz GMRS Repeater outputs (for simplex/direct/Talk-Around use).
FRS is limited to Narrow FM only. GMRS allows Wide FM for simplex or repeater use on chs. 1-7 & 15-22.
NFM = 12.5kHz, FM = 20kHz deviation in a 25kHz channel
ERP = Effective Radiated Power, PEP = Peak Envelope Power (Total Power Out)
Being in the UHF band between 462 & 467 MHz (megahertz), GMRS radios are particularly useful for indoor and urban settings, because these higher frequencies have a tendency to reflect and bounce around between obstructions, and thus reach their destination when lower VHF frequencies would otherwise be absorbed and fall off. On the same token, GMRS usually doesn’t do as well in rural, outdoor settings because the UHF waves tend to be absorbed more by trees and foliage, and don’t “bend” over hills as well as lower frequencies. This is why we recommend that your EmComm radio capabilities include both UHF GMRS and VHF MURS (and HAM radio if you are licensed), keeping you safe and in contact in just about any setting.
Unlike the FRS (Family Radio Service) Band, which most people use with cheap, throw-away blister-pack “walkie-talkie” radios with fixed antennas and very low power limits (formerly 0.5 Watts, but now are allowed up to 2 Watts on channels 1-7 and the GMRS channels 15-22 – repeater outputs/talkaround only), GMRS allows external antennas and up to 5 Watts ERP (Effective Radiated Power) on the simplex channels 1-14, and up to 50 Watts of power output on the repeater channels 15-30, greatly increasing your potential operating range and making a GMRS two-way radio a great choice for serious recreational, prepper or SHTF emergency communications. Note that radios using the new allowed digital positional data transmissions are still limited to having non-removable/fixed antennas,
We’ll be providing much more information about this band soon as it’s one of the most popular services used for EmComms (Emergency Communications) next to Amateur Radio!
This is a great hobby and has saved the day for me once. I came upon a flipped vehicle no cell service but was able to get them help using the GMRS radio in my car. I got on the repeater and had someone call 911. You never know when it will come in handy. I have given radios to my entire family. [BSR: Thanks for sharing your story RB!]
GMRS is great. I also think it’s the best all around service for the license type services available.
Ham is the best and I can’t wait to try some 10 meter bands when I get my technician license I’m studying for now.
