About the time signal transmitter
DCF77
The radio-controlled clock integrated into the weather
station receives its radio signal from the DCF77 time signal
transmitter. This broadcasts the precise and official time
of the Federal Republic of Germany on the long-wave
frequency of 77.5 kHz.
The transmitter is located in Mainflingen near Frankfurt
am Main and, with its range of up to 2000 km, supplies the
majority of radio-controlled clocks in western Europe with
the necessary radio signals.
As soon as the base station is supplied with current, it
switches to receiving mode and searches for the signal
from the DCF77 transmitter. If the time signal is received in
sufficient strength, the display shows the date and time.
The base station switches on multiple times daily and
synchronises the time with the radio signal from the
DCF77 transmitter. In the event the signal is not received,
e.g. during a strong storm, the device continues to run
precisely and then switches to receiving mode again at the
next scheduled time.
