Family Radio Service
From The RadioReference Wiki
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 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. Power output is limited to 2 watts on the 462 MHz channels (1-7 and 15-22), and 1/2 watt on the 467 MHz channels (8-14). Bandwidth is limited to 12.5 kHz (2.5 kHz peak deviation) on all channels. GMRS users may also communicate with FRS users since all FRS frequencies are now shared with GMRS.

Some groups try to consistently use the same channel / tone combinations.

Most FRS radios have CTCSS capability. Some higher end units may also have DCS. 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:
|CTCSS tone (Hz)||Commonly assigned "code"|
American-standard FRS radios have been approved for use in Canada since April 2000. The revised technical standard RSS 210 has essentially the same technical requirements as in the United States. Since September 2004,low-power GMRS radios and dual-standard FRS/GMRS radios have also been approved for use in Canada, giving additional channels. In Canada, no license is required and no restrictions are imposed on the GMRS channels.

Since tourists often bring their FRS radios with them, and since trade between the U.S., Canada, and Mexico is of great value to all three countries, the Mexican Secretary of Communication and Transportation has authorized use of the FRS frequencies and equipment similar to that in the US. However, dual-mode FRS/GMRS equipment is not approved in Mexico, so caution should be exercised in operating hybrid FRS/GMRS devices purchased elsewhere. http://web.archive.org/web/20091026203800/http://geocities.com/wd9ewk/xe-frs.html Mexico's Family Radio Service (FRS) equivalent retrieved 2009 Oct 23
