Radio Controlled Wall Clocks |
Radio controlled clocks receive
wireless time codes and synchronize to the Coordinated Universal
Time (UTC) within a fraction of a second. This technology has
been extended to a wide variety of desk clocks, wall
clocks and wrist watches that synchronize to radio stations
such as WWVB, NIST and similar stations in other countries.
The guaranteed precision in time is the distinguishing
feature of a radio controlled clock, and is
also the reason why a radio controlled clock
commands an edge over the conventional clock.
Though radio controlled clocks have been present
ever since the existence of radio, the technology
was much expensive then. Advancement in technology
and low costs of production has made the purchase
of a radio controlled clock an affordable
one.
Though some believe that the radio controlled
clock and an atomic clock are one and the
same, here is the reason why the two are different:
-
The radio controlled
clock receives the signals from a place
which has an atomic clock. The radio controlled
clocks have a radio inside.
-
Atomic clocks have an
atomic oscillator inside. Such oscillators
are usually cesium or rubidium oscillators.
-
The radio controlled
clocks decode the signals received from
the radio station and synchronizes the time
accordingly.
-
Keep clocks away from
computers, minimum distance being 1-2 meters.
-
Replace batteries as
and when necessary
-
Place the clock in the
direction facing the radio station
-
Metal shielding can
interfere with the functioning of the clock
- You can check the timings of your clock
vis a vis the radio station through the net
or by listening to the radio station.
