Atomic Time Reception
The main unit synchronizes the time and date with 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’s 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:
• During night-time hours, atmospheric disturbances are typically less severe and
radio signal reception may improve. A single daily reception is sufficient
enough to keep the clock accuracy within 1 second.
