The first way of managing the WWVB frequency in Fort Collins was to implement a phase-locked servo system exactly where a Regulate signal was broadcast from Boulder and been given in the station website. This technique was devised by Chesley Looney of NASA [fifty five] and was initial implemented by NBS to regulate the frequency of WWVL even though it had been situated in Sunset, Colorado. The twenty kHz signal from WWVL was gained in Boulder, wherever it absolutely was in comparison with the national normal.
