The broadcast comes from WWVB, a station run by the National Institute for Standards and Technology. WWVB marks half a century as the nation’s official time broadcaster on July 5. Together with its sister station, WWV, which is about to hit 90 years in service, NIST radio has been an invisible piece of American infrastructure that has advanced industries from entertainment to telecommunications. (WWV’s broadcast includes a wider range of information, including maritime weather warnings and solar storm alerts).
Probably a bit of "not so relevant trivia", back in another lifetime, while circumventing the globe courtesy Uncle Sam's U.S. Navy, in the days before Satellites etc, Uncle's ships HAD to tune into WWV for time signals, (not always an easy chore due to location, atmospherics and quality of the receiving equipment etc) once a day to sync/compensate their chronometers. Part of my duties as a "Radioman" included finding WWV, which broadcasted on AM radio in 5KB increments as I recall. For those without old "sealegs" the chronometers provided part of the necessary info required to Navigate.
