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 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
Projection alarm. However, due to the nature of the Earth’s Ionosphere,
reception is very limited during daylight hours. The Projection alarm will search
for a signal every night when reception is best.
The WWVB radio station receives the time data 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 detail,
visit http://www.boulder.nist.gov/timefreq.htm. To listen to the NIST time, call
(303)499-7111. This number will connect you to an automated time, announced
at the top of the minute in “Coordinated Universal Time”, which is also known as
Greenwich Mean Time (GMT). This time does not follow Daylight Saving Time
changes. After the top of the minute, a tone will sound for every second. It is
possible that your Projection Alarm may not be exactly on the second due to the
