What are GMRS repeaters?
A “repeater” is a special kind of base station that retransmits the signals of other stations. A conventional repeater receives on a GMRS frequency in the 467 MHz band, and simultaneously retransmits that signal on a GMRS frequency in the 462 MHz band. The separation between those two frequencies is usually 5.000 MHz. Most repeaters retransmit only those signals on which is imposed one or more of the approximately three dozen subaudible tone codes, or one or more of the approximately six dozen subaudible digital codes. There is also a new kind of repeater that retransmits not simultaneously, but in a time-delay mode. There are only a few such stations in the current edition of the Guide, but there will likely be many more in the future. This kind of repeater can be distinguished in that the user will hear that station retransmit his or her own signal back shortly after he or she releases the local microphone “push to talk” button.
