DCF 77 RADIO CONTROLLED CLOCK
The remote sensor receives 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 transmits 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 1,500 km from the transmitter. Then the remote sensor
transmits the time signal to the weather station to display the accurate time. However, there
are many environment factors may affect the RCC reception, i.e. nearby computer monitors or
other electronic devices, put on any metal surface, surrounded by any tall buildings and so on.
The user had better to place the remote sensor away from metallic structures and face the
transmitter in Mainflingen-near Frankfurt, Germany.
