GMRS: The General Mobile Radio Service (GMRS) is a land-mobile FM UHF radio service designed for short-distance two-way communication. Licensed.
FRS: The Family Radio Service (FRS) is a mobile radio system authorized in the United States since 1996. This personal radio service uses channelized frequencies around 462 and 467 MHz in the ultra high frequency (UHF) band. Unlicensed.
FRS/GMRS Channels
Channel numbers commonly used on 22 channel FRS/GMRS dual service radios. Most radios of this type are not capable of repeater operation and do not include the repeater input frequencies.
