The RADIO-CONTROLLED Clock
With the Radio-Controlled Clock, you can have the most accurate time within the continent. It
can receive the time signal transmitted by Physikalisch-Technische Bundesanstalt (PTB) of
Germany, which is regulated by 4 atomic clocks and in average deviates less than 1 second in
2 million years.
PTB transmit the time signal (DCF77, 77.5kHz) continuously from Mainflingen, 25 km
southeast of Frankfurt (am Main). It is expected that the signal can cover a distance of 2,000
km from the transmitter. However, some environmental effects (see Attention below) may
affect the transmitting distance.
For more information, please study the WEB page of PTB at: http://www.ptb.de
