GMRS Radio Basics for Families

What GMRS is, how the FCC license works ($35, 10 years, covers family), and how to set up and talk on a GMRS handheld. Not legal advice.

Not legal advice. FCC rules change; read the current rules (47 C.F.R. Part 95, Subpart E) and the FCC's GMRS page before you transmit.

What it's for

When cell towers are down or jammed, a GMRS radio lets the outfit talk across the ranch, the neighborhood, or the campground. The FCC describes GMRS as a licensed radio service for short-distance, two-way voice using handhelds, mobile radios, and repeaters, with an expected range of one to twenty-five miles depending on station type, terrain, and repeater use. The Lookout keeps the radios charged and the plan straight.

Before you need it (practice)

Get the license first

  • An FCC license is required to operate a GMRS system (FCC).
  • Who can apply: individuals 18 or older who aren't representatives of a foreign government (FCC).
  • Fee: the FCC's fee guide lists $35 for a new GMRS license application (fee code PRAM), with no separate regulatory fee. Check the current fee page before you apply.
  • Term: licenses run ten years and can be renewed starting 90 days before they expire (FCC).
  • Family: once licensed, any family member, regardless of age, can operate stations within your licensed system (FCC).
  • The FCC's GMRS page lists no exam requirement (ham radio is different).
  • Apply online through the FCC's licensing system (Form 605). You'll get a call sign. Write it on tape on every radio.

Learn your radio

  • Read the manual cover to cover once. Find: channel select, volume, squelch/monitor, power level, the lock, and how to turn privacy codes on and off.
  • Charge or load batteries and do a range walk: one person stays home, the other walks or drives out and checks in every few blocks. Note where it drops.

Step by step

  1. Pick your channel from your family plan (see Walkie-Talkie Channel Plan).
  2. Listen first. No GMRS channel belongs to anyone. The FCC asks users to follow a "listen-before-talk" etiquette. Turn privacy codes off or press monitor to hear whether the channel is busy.
  3. Press the talk button and speak per your radio's manual.
  4. Keep it short. "Ma, this is Jake. At the north gate, all good. Over."
  5. Release the button to listen. Radios can't send and receive at the same time.
  6. Identify with your call sign. The rules require you to give your FCC call sign at the end of a transmission or series of transmissions, and at least every 15 minutes during a longer series (47 C.F.R. § 95.1751). Voice in English works.
  7. Mind the terrain. The FCC says range depends on station type, terrain, and repeaters.

Common mistakes

  • Transmitting before you're licensed. FRS radios need no license; GMRS does.
  • Thinking privacy codes make it private. They only filter what your radio hears. Anyone on that frequency can still hear you.
  • Linking repeaters over the internet. The FCC says that violates the GMRS rules.
  • Dead batteries on the day. Keep spares, and see Headlamps, Batteries, Solar, and Faraday Storage.
  • Expecting 25 miles from a handheld in a valley. That top figure depends on station class and repeaters.

Care & storage

  • Store radios with batteries removed or topped up per the manual, in a dry spot.
  • Keep a printed card with call sign, channels, and check-in times in each radio's case.
  • Track your license expiration date. Renewal opens 90 days before it.
