"What is Family Radio Service? (from http://wireless.fcc.gov/prs/famrad.html)The Family Radio Service ("FRS") is one of the Citizens Band Radio Services. It is for your family, friends and associates to communicate among yourselves within your neighborhood and while on group outings. You cannot make a telephone call with a FRS unit. You may use your FRS unit for business-related communications. Expect a communication range of less than one mile.
Which FRS channels may I use?You may use any of the 14 FRS channels on a "take turns" basis. No FRS channel is assigned to any specific individual or organization." http://frwebgate.access.gpo.gov/cgi-bin/get-cfr.cgi?TITLE=47&PART=95&SECTION=627&YEAR=2000&TYPE=TEXT

"What is the General Mobile Radio Service? (from http://wireless.fcc.gov/prs/genmbl.html/)The General Mobile Radio Service ("GMRS") is a personal radio service available to an individual (one man or one woman). It is a two-way voice communication service to facilitate the activities of the individual's immediate family members. Expect a communications range of five to twenty-five miles. You cannot make a telephone call with a GMRS unit.
Which GMRS channels may I use?There are twenty-three GMRS channels. None of the GMRS channels are assigned for the exclusive use of any system. License applicants and licensees must cooperate in the selection and use of the channels in order to make the most effective use of them and to reduce the possibility of interference. Any mobile station or small base station in a GMRS system operating in the simplex mode may transmit voice type emissions with no more than 5 watts ERP on the following 462 MHz channels: 462.5625, 462.5875, 462.6125, 462.6375, 462.6625, 462.6875 and 462.7125 MHz. These channels are shared with the Family Radio Service. Any mobile station in a GMRS system may transmit on the 467.675 MHz channel to communicate through a mobile relay station transmitting on the 462.675 MHz channel. Each licensee must select the channel(s) or channel pair(s)for the stations in the proposed system from the following list: For a base station, mobile relay station, fixed station or mobile station: 462.550, 462.575, 462.600, 462.625, 462.650, 462.675, 462.700 and 462.725 MHz. For a mobile station, control station or fixed station in a duplex system: 467.550, 467.575, 467.600, 467.625, 467.650, 467.675, 467.700 and 467.725 MHz. Every GMRS system station operator must cooperate in sharing the assigned channel with station operators in other GMRS systems by monitoring the channel before initiating transmissions, waiting until communications in progress are completed before initiating transmissions, engaging in only permissible communications and limiting transmissions to the minimum practical transmission time." http://frwebgate.access.gpo.gov/cgi-bin/get-cfr.cgi?TITLE=47&PART=95&SECTION=621&YEAR=2000&TYPE=TEXT TITLE 47--TELECOMMUNICATION

(b) Each GMRS transmitter for mobile station, small base station and
control station operation must be maintained within a frequency
tolerance of 0.0005%. Each GMRS transmitter for base station (except
small base), mobile relay station or fixed station operation must be
