General Mobile Radio Service (Family two-way Radios)
True GMRS radios operate on 15 UHF frequencies that were set aside by the FCC for family use. A license is required (Reduced from $85 to $65.00 for a five year term) which covers your entire family, including (grandparents, parents, brothers, sisters, cousins, aunts, uncles, in-laws, sons, daughters, and pretty much any one related by blood or marriage). The purpose is to facilitate the communications of families over a long distance. You can use 8 times the power of big box store radios and Radio Repeaters which helps your signal cover larger geographic areas.
