GMRS Channels & Frequencies: Chart for Off-Road Riders

GMRS channels and frequencies help an off-road group put compatible radios on the same settings. The chart below covers the 22 commonly numbered shared GMRS/FRS simplex channels in the United States. GMRS also uses eight 467 MHz main frequencies as repeater inputs.

Rules and channel numbering are separate: match the frequency and radio service, not just a display number. Use equipment authorized for the service and follow its manual.

GMRS and FRS frequency chart

*On the 462 MHz main channels, 50 W is the maximum transmitter output for mobile, repeater and base stations; fixed stations are limited to 15 W. On 462 MHz interstitial channels, the 5 W limit is effective radiated power (ERP). On 467 MHz interstitial channels, only handheld portable GMRS units may transmit, at up to 0.5 W ERP. Your radio may support less power or omit some channels.

Source rules: GMRS frequencies, GMRS power limits, FRS channels and FRS power limits.

Do you need a GMRS license?

A valid individual license is required to operate a GMRS station. Eligible immediate family members may operate under a licensee's authority as specified in 47 CFR 95.1705. Do not assume every friend in a riding group is covered by one person's license. FRS is a different service; identify the actual radio's authorization before deciding which rules apply.

GMRS repeater frequencies

The eight main 462 MHz frequencies in channels 15–22 pair with inputs 5 MHz higher: 467.5500, 467.5750, 467.6000, 467.6250, 467.6500, 467.6750, 467.7000 and 467.7250 MHz. A repeater-capable GMRS radio transmits on the input and receives the corresponding 462 MHz output. These inputs are different from the low-power 467 MHz interstitial frequencies on channels 8–14.

Check the repeater owner's access conditions, tone settings and operating instructions. A standard FRS radio cannot provide GMRS repeater operation simply because it has 22 channels.

Can GMRS and FRS radios talk to each other?

Compatible radios can communicate on shared simplex frequencies when their settings match. Confirm the channel, any tone or digital-code setting, and the mode. CTCSS/DCS codes filter what the speaker opens for; they do not encrypt conversations or create a private channel. Code numbers may differ between brands, so compare the actual tone or code in the manuals.

Choose settings before the group leaves

1. Identify each radio model and service.
2. Select a shared frequency supported by every radio.
3. Start a compatibility check with tone/code filtering disabled, then configure it consistently if needed.
4. Test both directions between vehicles while parked.
5. Agree on a backup channel and a regrouping plan if contact is lost.

Terrain, obstructions and installation affect real-world range. There is no single best GMRS channel for every trail. For consumer handhelds, see our Cobra microTALK setup guide; for installed systems, compare UTV communication equipment.
