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
