ATOMIC TIME RECEPTION
The main unit synchronizes the time and date with WWVB radio clock broadcasts maintaining the
atomic time precision.
WWVB RADIO CONTROLLED TIME
The NIST (National Institute of Standards and Technology) radio station (WWVB) is located in Ft. Collins,
Colorado. It transmits an exact time signal continuously throughout the most of the continental United
States at 60 KHz frequency. The Atomic Time Clock in your weather station can receive this WWVB
signal through the internal antenna from up to 2,000 miles away. Due to the nature of the Earth
ʼs
ionosphere, reception can be limited during the daylight hours. The radio controlled clock will search
for an alternate station that receives the atomic time signal from the NIST Atomic clock in Boulder,
Colorado.
The WWVB tower icon on the unit’s display will flash indicating a radio signal reception from the WWVB
station. If the tower icon is not fully lit, or if the time and date are not set automatically, please consider
the following:
