In the United States, GMRS (General Mobile Radio Service) operates on specific frequencies allocated by the Federal Communications Commission (FCC). GMRS channel 5 is designated for simplex communications, meaning it's intended for direct radio-to-radio communication between users within range, without the use of repeaters.
Using a repeater on GMRS channel 5 without proper authorization or licensing would likely be considered illegal. Repeater operation on GMRS requires a separate FCC license, and the frequencies used for repeaters are different from those used for simplex channels.
Operating a repeater without the proper authorization can result in fines, license revocation, and other penalties imposed by the FCC. It's important for GMRS users to understand and comply with the regulations to ensure legal and responsible use of the radio spectrum.
