Our Radio Controlled clocks can be manually set and used anywhere. Our Rwave, Atomic, Radio Controlled clocks do not receive or process radio controlled time signals from Germany’s DCF 77, Japan’s J Ga AS, or England’s MSFs atomically regulated transmitters. When the clock is exposed to the WWVB signal it will automatically set the hands to the exact time.

In buildings that WWVB cannot penetrate you may set the time using the manual time set button. It is not possible, however, for WWVB to penetrate most indoor shopping malls and rooms in the center of large office buildings that do not have windows. 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. These physicists have created an international standard, measuring a second as 9,192,631,770 vibrations of a Cesium 133 atom in a vacuum.
A team of atomic physicists continually measures every second of every day to an accuracy of ten billionths of a second per day. Today, time is precisely measured in the United States by the 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. Since the beginning of time, man has been fascinated with the measurement of time and has devised more accurate machines to trap and measure time. And nothing keeps track of time more precisely and trouble free than our radio controlled clocks.
