GMRS & FRS Frequencies & CTCSS

GMRS Frequencies

Operation on these frequencies requires a GMRS FCC license - $75 for 5 years.

GMRS Interstitial Simplex & FRS Frequencies

Interstitial frequencies are available for simplex use by all GMRS licensees. Operation on these channels is restricted to GMRS Small Base Stations and GMRS mobile units operating with 5 watts or less of effective radiated power. GMRS shares these channels with the hand-held radios of the Family Radio Service. FRS radios are limited to 0.5 watts. Operation on these frequencies is license-free with an FRS radio, but requires a license with a GMRS radio.

FRS ch. 1 is frequently used as a calling channel.

CTCSS (PL^®) Tones for various radios

If you want GMRS and FRS radios of differing brands to talk to each other, you'll need this info.

Note many FRS makers call these "privacy codes." Be aware that there's nothing private about it - any scanner can pick up FRS, regardless of the "privacy code" setting.
