The DCF77 control electronics were adapted such that the data input to bits 1 to 14 which are broadcast via amplitude modulation is now provided by a third party. The contractual relation between PTB and T-Systems was changed accordingly. Primarily, these bits shall be used for the purpose of public warning. In addition weather data are transmitted, which are supplied by the Swiss firm Meteo Time GmbH. The same data are transmitted also by the Swiss standard frequency and time signal service HBG (75 kHz). The PTB explicitly denies any responsibility for the data content transmitted during bits 1 to14. Radio-controlled clocks manufactured and operated up to now are not disturbed by the new service, but cannot make use of it.
Cierto, la señal DCF77 transmite informacion meteorologica.
