7. e most accurate clock in North America the Atomic Clock of the US National Institute of Standards and Technology Time and Frequency Division in Boulder Colorado A team of atomic physicists continually measures 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 This atomic clock regulates the WWVB radio transmitter located in Fort Collins Colorado where the exact time signal is continuously broadcast throughout the United States at 60 kHz to take advantage of stable long wave radio paths found in that frequency range Radio waves at these low frequencies use the earth and the ionosphere as a wave guide and follow the curvature of the earth for long distances The built in antenna system will receive the WWVB signal anywhere in North America within 2000 miles of Fort Collins where long wave radio reception is undisturbed A microprocessor activates the receiver and processes the time signal from Fort Collins overnight Through the radio signals La Crosse Technology atomic clocks always keep precise time The changeover from standard time to daylight saving time and vice versa takes place automatically with the same precision ADDITIONAL DETAILS To set up your clock simply install one fresh AA LR6 ALKALINE battery Due to the nature of long wave radio signals it is normally not
