Today I received my GRMS (General Mobile Radio Service) license. The license is easy enough to get, just fill out the FCC form and pay $70. The General Mobile Radio Service (GMRS) is a licensed radio service that uses channels around 462 MHz and 467 MHz. The most common use of GMRS channels is for short-distance, two-way voice communications using hand-held radios, mobile radios, and repeater systems.
