ABOUT WWVB (Radio Controlled Time)
The NIST (National Institute of Standards and Technology—Time and Frequency Division) WWVB radio
station is located in Ft. Collins, Colorado, and transmits the exact time and date signal continuously throughout
the United States at 60 kHz. The signal can be received up to 2,000 miles away through the internal antenna in
the Weather Station. However, due to the nature of the Earth's Ionosphere, reception is very limited during
daylight hours. The weather station will search for a signal every night when reception is best. The WWVB
radio station derives its signal from the NIST Atomic clock in Boulder, Colorado. A team of atomic physicists
is continually measuring every second, of every day, to an accuracy of ten billionths of a second per day. These
physicists have created an international standard, measuring a second as 9,192,631,770 vibrations of a Cesium-
133 atom in a vacuum. For more information on the atomic clock and WWVB please see the NIST website at
