DCF77

DCF77 is a German longwave time flag and standard-recurrence radio station. It began administration as a standard-recurrence station on 1 January 1959. In June 1973 date and time data was included. Its essential and reinforcement transmitter are situated in Mainflingen, around 25 km south-east of Frankfurt am Main, Germany. The transmitter creates an ostensible intensity of 50 kW, of which around 30 to 35 kW can be emanated by means of a T-reception apparatus. DCF77 is constrained by the Physikalisch-Technische Bundesanstalt PTB, Germany's national material science research facility and transmits in nonstop activity 24 hours.

Most administration interferences are momentary detachments of under two minutes. Longer enduring transmission administration interferences are for the most part brought about by solid breezes, solidifying precipitation or snow instigated T-radio wire development. This shows itself in electrical detuning of the reception apparatus reverberation circuit and henceforth a quantifiable stage balance of the got flag. At the point when the maladjustment is excessively vast, the transmitter is removed from administration briefly. In the year 2002, practically 99.95% accessibility, or simply over 4.38 long stretches of vacation, was figured it out. The timestamp sent is either in Coordinated Universal Time UTC+1 or UTC+2 relying upon sunshine sparing time.
