What exactly are FRS Radios?
FRS radios are small, handheld two-way radios designed for short range communications. The FCC authorized these radios several years ago after a petition from Radio Shack to create the new service.
The range on these radios is not that great--just enough to work around the farm, local mall or amusement park.
Note: Many of the newer radios that advertise 3-, 5- and 10-miles ranges are so-called FRS/GMRS “hybrid” radios, because the also work in the GMRS band. We have a separate section of our site dedicated to the pros and cons of these new radios.
Randy Hefner has a nice site that describe FRS in detail.
Jesse’s has a comprehensive list of FRS radios from all major manufacturers. More info on FRS and GMRS at Rick’s Radio Page
The Travel Insider has a 3-part article that discusses all aspects of the different radio services.

Range of FRS Radios
FRS radios use the same spectrum as GMRS radios. The range of FRS is generally limited to line-of-sight, that is, if you can see the person, you will likely be able to communicate with them using the radios. Under normal circumstances, expect about 1/2 mile to 1 mile in congested areas, more over open terrain. The claims of 2 to 5 miles may be valid if you are on one mountain peak, and the other people is on another mountain peak.
Popular Wireless has a great article on The Truth Behind the Marketing Claims for FRS and GMRS radios.
SC&E has a nice chart outlining the range differences between FRS, GMRS, and MURS.

FRS Repeaters
Technically, the FCC does not allow repeaters on FRS frequencies. That has not stopped some creative individuals from using technology to bend the rules:

FRS Channels
Almost all FRS radios support 14 channels. Some “hybrid radios” (combination FRS and GMRS) may only support the first (or last) seven FRS channels. Note that not all radios support Privacy Codes (CTCSS) to lock our undesired messages (see below).

CTCSS Codes
CTCSS (Carrier Tone Coded Squelch System) tones, also known “Privacy Codes”, are used to keep the speaker turned off until another radio with the same code is used. This way, multiple groups of people can be using the same channel, and they will only hear the communications destined for their group.
The codes listed below are “industry standard”, but each radio manufacturer may choose their own codes, leading the possibility of some codes not working with incompatible radios. Popular Wireless has a sample list of codes from six types of FRS radios.
