FRS and GMRS are relatively new radio bands which have been opened to the general public. FRS and GMRS radios are compact handhelds and use FM transmission in the UHF radio band. They are very handy for personal communications such as at malls, carnivals, vacations, etc. Cobra offers a variety of models.
FRS and GMRS radios operate at a much higher frequency than CB (approximately 465 megahertz, compared with 27 megahertz for CB). They therefore cannot communicate with CB radios.
