TIME AND SIGNAL STANDARD FREQUENCY RADIO DCF77 ON 77.5 KHZ

DCF77 is a long wave time signal and standard-frequency radio station. Its primary and backup transmitter are located at 50°0′56″N 9°00′39″E in Mainflingen, about 25 km south-east of Frankfurt am Main, Germany. The timestamp sent is either in UTC+1 or UTC+2 depending on daylight saving time. The 77.5 kHz carrier signal is generated from local atomic clocks that are linked with the German master clocks at the PTB in Braunschweig. Radio clocks and watches have been very popular in Europe since the late 1980s and, in main-land Europe, most of them use the DCF77 signal to set their time automatically.
