Solid Signal is an Authorized Reseller of La Crosse Technology products.
This elegant atomic clock has a deep cherry finish and displays the most precise and accurate time possible. A radio signal is received daily from Colorado that updates the atomic clock to within one second of official U.S. government time. The atomic clock even automatically resets for Daylight Savings Time! The atomic clock displays indoor and outdoor temperatures, moon phase, and includes day/date in your choice of four languages.

Features


  • Available in Cherry, Oak, Or Ivory

  • Sets automatically to WWVB radio signal (manual setting is also possible)

  • User-selectable 12- or 24-hour time display. Hour and minutes are separated by a flashing colon (:) that indicates seconds

  • Daily alarm setting with snooze function

  • Calendar display with weekday abbreviations in your choice of four languages: English, French, Spanish, or German

  • Time zone setting (13 available)

  • Daylight saving time ON/OFF option

  • Moon phase (12 phase icons)

Radio-Controlled Time:
The NIST (National Institute of Standards and Technology, Time and Frequency Division) maintains a radio station, WWVB, in Ft. Collins, Colorado. 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.

WWVB (the station’s identification just like any other radio station) continuously broadcasts time and frequency signals at 60 kHz. The carrier frequency provides a stable frequency reference traceable to the national standard. There are no voice announcements on the station, but a time code is synchronized with the 60 kHz carrier and is broadcast continuously at a rate of 1 bit per second using pulse width modulation. The time code contains the year, day of year, hour, minute, second, and flags that indicate the status of Daylight Saving Time, leap years, and leap seconds.

The La Crosse Technology WS-8117U-IT-C Digital Atomic Clock:
The La Crosse Technology Digital Atomic Clock maintains its incredible accuracy by automatically tuning into the WWVB radio signal. The built-in antenna ensures reliable signal reception up to 2000 miles (3200km) from the WWVB transmitter. As a result, the La Crosse Technology clock will calibrate to the atomic clock not only throughout the mainland U.S. but also in much of Canada. You need only insert the batteries, wait until the signal is received, and program the desired additional settings. In locations outside of WWVB range, the La Crosse clock can be manually set and will provide the high degree of accuracy of any quality quartz clock.

In a nutshell, here’s how the La Crosse clock works: The clocks antenna is specifically tuned for optimal reception of the 60 kHz time signal. The time signal received on the antenna is demodulated by an onboard receiver, which sends the information to the clocks CMOS microprocessor for decoding. Once your clock has automatically set its time for the first time, it ensures continuing accuracy by automatically tuning into the WWVB radio signal once per day at midnight. (If no signal is detected, the clock performs its WWVB check hourly until the signal is found.) As long as your clock is kept within transmitter range, it will continue to display the absolutely precise time, automatically adjusting for summer time/winter time changeovers if the daylight savings time option is ON. Should you move your clock out of transmitter range for an extended period of time, the clock will continue to operate as a highly accurate quartz-controlled clock. Upon re-entering the transmitter range, your clock will correct itself again to the precise WWVB time signal.
