Summary

DescriptionLow cost DCF77 receiver.jpg	English: Low cost DCF77 receiver module. This is a radio receiver used in a radio clock, a quartz clock which is periodically set to the correct time by radio signals synchronized with an atomic clock from a government radio station. This one receives the coded time signals broadcast by German government time radio station DCF77 on 77.5 kHz. The ferrite loopstick (left) is the radio's antenna, and with the attached capacitor also serves as its tuned circuit. Français : Module de réception DCF77 à faible coût Deutsch: Billiger DCF77 Empfänger Modul Nederlands: Goedkope DCF77 ontvangstmodule. Dit is een radio-ontvanger zoals gebruikt in een radioklok, een kwartsklok die periodiek wordt gelijkgezet met het radiosignaal afkomstig van een overheidszender, dat wordt gesynchroniseerd met een atoomklok. Dit exemplaar ontvangt tijdcodesignalen van het Duitse radiostation DCF77 op 77,5 kHz. De ferrietstaaf met spoel (links) fungeert als ontvangstantenne; deze vormt bovendien een afgestemde kring samen met de eraan bevestigde condensator.
