DCF77 Radio Time Receiver


The DCF77 radio clock systems from GUDE enable the synchronization of individual clients with the atomic-precise radio time of the DCF77 signal. The devices of the Expert Mouse Clock Series are simply connected to the PC. After successful installation, they permanently synchronize the internal PC clock. There are devices with serial or USB interface as well as with integrated or external antenna available.

DCF77 radio clocks synchronize with a reference time source on the Universal Time Coordinated (UTC). This reference time source is based on an exactly running atomic clock of the time signal transmitter DCF77. A time in UTC results in the corresponding Central European Time (CET) in Germany, Austria and other Central European countries, adding one hour. The summer Central European Summer Time (CEST) is obtained by adding two hours.

                                      DCF77 - This abbreviation stands for: D: Germany, C: Longwave transmitter, F: Frankfurt am Main, 77: Transmission frequency 77.5 kHz.
This reference time transmitter is a long-wave transmitter in Mainflingen near Frankfurt am Main, Germany. With a range of 1,500 km, it supplies Germany and the west of Europe with the legal time. The transmitter has an accuracy with a relative standard deviation of the transmitted time of a maximum of 10-12. That corresponds to a lapse of one second in 30,000 years.
