GMRS Channel Reference

FCC Part 95 allocations for 30-channel FRS/GMRS radios. Pair with your free GMRS reference card for local repeater tones.

How to read this chart

  • Simplex OK — legitimate direct radio-to-radio use. Best bets: Ch 15–22 (GMRS up to 50 W) and Ch 22 for calling.
  • Repeater output — what your radio receives from a repeater (462 MHz on Ch 1–7 and 15–22).
  • Repeater input — what portables transmit on to hit a repeater (+5 MHz). Ch 8–14 and 23–30 are not simplex channels despite what some radio menus imply.
  • Ch 1–7: FRS 2 W / GMRS 5 W only (not 50 W). Ch 8–14: 0.5 W max. Ch 15–22: FRS 2 W / GMRS 50 W ERP.
  • Ch 23–30: GMRS licensed only — repeater inputs paired with Ch 15–22 outputs. FRS not authorized.

Power limits are ERP per FCC rules (2017 reform). GMRS license required for GMRS power levels. Always confirm tones and coordinator rules for local repeaters.

Channels 1–30

Standard repeater pairs (+5 MHz)

When programming a repeater: set output to the 462 MHz channel, input to the matching 467 MHz channel.

Common questions

What GMRS channels are repeater vs simplex?

Channels 15–22 are typically repeater inputs/outputs; Ch 1–7 and 15–22 simplex are common for handheld use. Always verify local coordination.

Do I need a license for GMRS?

Yes — GMRS requires an FCC license (no exam). Family members may operate under the licensee's supervision per FCC rules.
