GMRS, FRS, MURS and PMR446 frequencies: channel charts

Channel charts

Frequencies, power limits and channel widths come from the rules themselves: the US Code of Federal Regulations, Canada’s RSS-210, the CEPT decisions European countries implement, and German and UK national rules. Channel numbers 1–16 for PMR446 and 1–5 for MURS are the numbering radios use; the rules list frequencies only.

FRS and GMRS frequencies

The 22 FRS and GMRS channels share frequencies. Power is the most a radio may send on each channel: effective radiated power for FRS and GMRS 1–14, transmitter output for GMRS 15–22.1 2 8

GMRS repeater channels

A GMRS repeater listens on a 467 MHz input and sends on a 462 MHz output. The rule lists both groups; pairing the same last digits, 5 MHz apart, is the usual practice.2 6

PMR446 frequencies (Europe and UK)

License-exempt, hand-held only, a built-in antenna and at most 0.5 W; no base stations or repeaters, and a transmission stops after 180 seconds.10 European regulators are preparing a 1 W limit, with the built-in antenna kept; it is not in force.13 In the UK, radio equipment that meets Ofcom’s interface requirement IR 2030 is license-exempt.17

Questions

What are the GMRS frequencies?

GMRS uses 22 simplex channels from 462.5500 to 467.7125 MHz, the same frequencies as FRS, plus eight repeater input channels from 467.5500 to 467.7250 MHz. Channels 1–7 allow 5 W, 8–14 only 0.5 W from a hand-held, and 15–22 up to 50 W from mobile and base radios.2

Can FRS and GMRS radios talk to each other?

Yes. FRS channels 1–22 are on the same frequencies as GMRS channels 1–22, so the radios hear each other on the same channel number and privacy code. The GMRS user needs a license; the FRS user does not.1 2

Is there a GMRS emergency channel?

Not by rule. FCC rules let any GMRS channel be used for emergencies or to help a traveler, and give emergency traffic priority on all of them. Channel 20 (462.675 MHz) is used for calling and travel help by custom.2

Do I need a license for GMRS?

Yes, an individual FCC license. It costs $35, lasts 10 years and is open to anyone 18 or older; your immediate family may use it too. You give your call sign at the end of a conversation and at least every 15 minutes.2 5

What are the MURS frequencies?

151.820, 151.880 and 151.940 MHz (11.25 kHz wide) and 154.570 and 154.600 MHz (20 kHz wide). MURS needs no license in the US, is limited to 2 W and may not use repeaters. The two upper channels are often called Blue Dot and Green Dot; those are trade names.3

What are the PMR446 frequencies?

16 analogue channels from 446.00625 to 446.19375 MHz, 12.5 kHz apart, at 0.5 W from a hand-held with a built-in antenna, license-exempt in Europe. Digital radios use the same band as 16 channels of 12.5 kHz or 32 of 6.25 kHz. Before 2016 there were only 8 analogue channels.10 11

Are FRS and GMRS channels the same in Canada?

Yes: the same 22 frequencies and channel numbers, license-exempt, with 2 W on most channels and 0.5 W on 8–14. The US GMRS repeater channels are not available, and neither is MURS.8 9

What are CB channels 9 and 19 for?

In the US, channel 9 is for emergencies and traveler help only. Channel 19 is where truckers talk, by custom rather than by rule. US CB has allowed FM next to AM and single sideband since October 2021.4 7
