Most families already own FRS walkie-talkies. They’re great around the yard… until you step off the driveway. GMRS—General Mobile Radio Service—is the licensed “bigger brother” that opens the same familiar channels to real, local coverage for your household.
In this post, I’ll explain what GMRS is, why it matters, how the license actually works, and the simple rules that keep you legal and effective.
What GMRS Is (and isn’t)
GMRS is a two-way voice service designed for individual licensees and their families. It runs alongside FRS on the same 22 channels you already know, but the rules change: GMRS allows more power, detachable antennas, and access to repeaters on the main channels. That’s the difference between a backyard toy and a town-wide tool.
Think of it this way:
FRS: Simple, license-free, very short range, fixed antennas, low power.
GMRS: Licensed, up to 50W transmitter output on main channels, detachable antennas, repeater access, one license covers your household.
GMRS is not CB with batteries. CB is AM at 27 MHz; GMRS is FM at 462/467 MHz—cleaner audio, less noise, and a more practical local footprint for modern family life.
The License (it’s simpler than you think)
You apply at FCC.gov, pay $35, and the license lasts 10 years. One license covers your immediate family (spouse, kids, parents, grandparents, siblings, in-laws, etc.). Your call sign becomes visible in the public FCC database—just like every other licensed radio service. That’s normal and is how spectrum use is tracked.
Two important responsibilities come with that:
You’re responsible for proper operation under your license.
ID correctly: transmit your call sign every 15 minutes during a conversation and at the end.

Range Reality (not the box claims)
Those “36-mile” or “50-mile” labels? That’s packaging, not physics. Terrain and antennas decide range.
The real levers:
Power: Up to 50W transmitter output on the main 462/467 MHz channels for mobile/base/repeater; 15W for fixed stations.
Antennas: Detachable/external antennas matter more than raw watts.
Height & location: Higher and clear line-of-sight = more consistent coverage.
Repeaters: Where available, repeaters extend local reach—but treat them as helpful, not guaranteed.
In our area after Hurricane Helene, cell service was unreliable. We kept the neighborhood connected with GMRS simplex—no Internet, no 5G, just radio to radio. It worked because the plan was simple and the tools were reliable.
Channels & Power (quick guide)
GMRS provides 30 channels total: 16 main + 14 interstitial.
Main 462/467 MHz channels:
Mobiles/bases/repeaters up to 50W transmitter output
Fixed stations: up to 15W
462 MHz interstitials: ERP ≤ 5W
467 MHz interstitials: ERP ≤ 0.5W (handhelds only)
Data (for handhelds): brief location/text features are allowed with strict limits; no data on 467 main channels.
Privacy Tones Aren’t Privacy
CTCSS/DCS “privacy tones” do not make your conversation private. They simply tell your radio which signals to open squelch for. Anyone can still listen. GMRS is an open-air service. Operate with plain language, keep it clean, and remember to ID.
What’s Allowed (and what isn’t)
GMRS is for plain-language voice communications concerning personal or business activities. A few quick boundaries:
Allowed: Emergency traffic has priority. One-way test transmissions, brief hazard warnings, and traveler assistance are okay.
Not allowed: Encryption or messages designed to obscure meaning, entertainment/music, advertising or political ads, continuous transmissions.
Equipment: buy the right radios
Use FCC-certified GMRS equipment (Part 95E). Since 2019, new FRS/GMRS combo handhelds can’t be sold. If you’re shopping, verify the FCC ID and that it’s approved for GMRS (Part 95E). That avoids headaches and keeps you on the right side of the rules.
