WHOI Sea Grant's Low Power Radio Project: Sound Waves 1620 AM

Low Power Radio as a Communications Tool

Low Power Radio (LPR) is a specialized form of AM radio broadcasting first used in the 1970s to inform travelers of traffic and weather conditions. More recently it has been used in state and national parks, airports, and theme parks to provide information to specific audiences. Anyone with an AM radio can tune into the assigned frequency, as advertised on signs and brochures, and hear information about local attractions, lodging, boating and fishing, and other information and education that will encourage visitation and enlightened use of natural resources.
