GMRS Channel Reference

GMRS is the licensed UHF family radio service — $35 FCC fee, no exam, repeaters allowed. This table is the Part 95 channel plan so you can program a certified GMRS radio without guessing interstitial channels.

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.

CTCSS tones

GMRS channels versus FRS

Channels 1–7 are shared FRS/GMRS simplex. Channels 8–14 are FRS-only interstitial (0.5 W). Channels 15–22 are GMRS simplex plus repeater outputs; repeater inputs sit 5 MHz higher on 467 MHz. A GMRS license (WSAY664 is the KI4TQN household license) lets you use higher power and external antennas that FRS radios cannot.

In northeast Tennessee, NETNRC links GMRS machines — Johnson City 462.600/467.600 PL 88.5 is the usual example. District 7 SKYWARN runs a GMRS training net Tuesday 7:00 PM local on that linked system. Program repeater pairs with +5 MHz duplex and the published tone; simplex family use belongs on 15–22 without duplex.

Apply at FCC ULS, then follow first week on GMRS and the GMRS Tennessee landing page. FRS remains license-free if you accept yard-scale range — see FRS vs GMRS.

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.

Can FRS talk to GMRS?

Yes on shared simplex channels 1–7 and 15–22 if both radios are on the same frequency and no repeater offset is used. Repeater pairs are GMRS-only.

What PL tone do East TN GMRS repeaters use?

NETNRC Johnson City is commonly 88.5 Hz. Kingsport uses 136.5 Hz on 462.550. Always listen and confirm — tones change.
