The La Crosse Technology Weather Instruments WS-7078U weather station has a wireless indoor outdoor thermometer, plus indoor and outdoor hygrometer. It also has a weather-forecasting feature with three indicator icons based on an internal barometer. The station's incredibly accurate radio-controlled atomic clock has day/date/time displays, two independent alarm settings, and a snooze feature.

La Crosse Technology Weather Instruments WS7078 Weather Station

Cleanly styled in black and silver, the La Crosse Technology WS-7078UF Weather Station has plenty of convenient features, including an atomic clock with alarm functions. In addition to day/date/time, the station displays indoor temperature and humidity, outdoor temperature and humidity (via an included remote transmitter), forecasting information, and indoor comfort level. Install one or two optional remote transmitters, and get outdoor temperature and humidity data from additional locations.

Cleanly styled and compact, the station is silver and black in color and can be used as a freestanding unit or mounted on a wall.

The station's weather-forecasting feature senses barometric pressure over time and adjusts the indicator icons to provide accurate forecasts based on pressure trends. Another clever feature of the WS-7078U(F) is an indoor comfort level indicator with happy and sad face icons.

The station keeps a record of the minimum and maximum indoor and outdoor temperatures and humidity it has recorded, and these are available at the push of a button.

Not only will the station operate with up to three remote transmitters, four different transmitters are available. The TX6U reports remote temperature, and has no display of its own.  The TX3U reports remote temperature, and has an LCD display of its own. The TX4U (the one included with the station) reports both outdoor temperature and humidity. The TX3UP senses remote temperature via a probe for use in pools, spas, etc., and has an LCD display of its own.

The station's clock calibrates itself to the world's most accurate clock every night by receiving WWVB radio transmissions. These transmissions contain time information from the U.S. atomic clock source, operated by the U.S. Commerce Department near Boulder, Colorado. The built-in antenna ensures reliable signal reception up to 2000 miles (3200km) from the WWVB transmitter.

With its good looks and many convenient features, the WS-7078U(F) is perfect for almost any room in the house.

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 stations 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 Integral Atomic Clock:

The atomic clock integral to the WS-7078U 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 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 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 the atomic clock works: The clock's 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 clock's 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 between midnight and 6:00 a.m. 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.

One TX4U comes with the unit.

The TX6U, TX3U and TX3UP may also be used with this unit, up to a total of 3 remotes.

Note: This unit has atomic clock functionality.  The clock can receive time broadcasts from the U.S. Atomic clock transmitter in Colorado, and synchronize itself to the U.S. Atomic clock every night.  As long as the signal is strong where the clock is located, the clock will maintain accuracy to a fraction of a second, and reset itself for daylight savings time (unless you choose to disable the DST function).  However, if the clock is located where the signal is poor, due to metal in the construction of your building blocking the signal, or due to electrical interference from nearby electrical appliances or computers, then the clock may not always receive adequate signal.  Under these conditions, the clock may still synchronize occasionally, when weather conditions are ideal, or may need to be set manually.
