WWVB: A Half Century of Delivering Accurate Frequency and Time by Radio
Michael A. Lombardi, Glenn K. Nelson
In commemoration of its 50th anniversary of broadcasting from Fort Collins, Colorado, this paper provides a history of National Institute of Standards and Technology (NIST) radio station WWVB. The narrative describes the evolution of the station, from its origins as a source of standard frequency, to its current role as the source of time-of-day synchronization for many millions of radio controlled clocks.
