About the time signal transmitter DCF77

This radio-controlled clock receives its radio signals from the
time signal transmitter DCF77. 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 radio-controlled clock is supplied with power,
it switches to receiving mode and searches for the signal from
the transmitter DCF77. If the time signal is received in sufficient
strength, the time is displayed.
