Family Radio Service
The Family Radio Service, or FRS, is an unlicensed, simplex only, personal radio service in the US covered by Part 95 of the FCC's regulations. Hand-held FRS transceivers with a maximum output of 500 mW are typically used by families, children, and campers to communicate. Shopping malls, theme parks, and special events are all great locations to monitor FRS communications. Radios may not have external antennas or power amplifiers attached to them (See 47 CFR 95.194c).
GMRS users may also communicate with FRS users, and among each other, on the lower 7 channels in the 462 MHz range, with a maximum of 5 watts ERP on those channels.

[edit] Recognized Channels
Some groups try to consistently use the same channel/tone combinations. See below for tone equivalents.
- 01/CS - "Emergency"
- 11/22 - Birders (no roger beep, please)
- 14/38 - MilCom/Airshow Hobbyists (7/15 - backup)
Most FRS radios have CTCSS capability. The companies marketing the radios usually refer to these tones as "privacy codes" even though they provide no privacy. Instead of asking FRS users to understand the actual tone values, integers are used instead. Most, but not all, manufacturers use the same numbers as Motorola:
