MSF 60KHz and DCF77 radio time code receivers
484.02 MSF time signal receiver
Wharton 484 series radio time synchronisation receivers enable the time synchronisation 4000 series digital clocks, calendar clocks, time zone clocks and time servers to accurate DCF and MSF radio time code signals.
MSF transmits on 60kHz from Athorn in Cumbria (latitude 54° 55' N and longitude 3° 15' W) with signals traceable to an atomic clock at the National Physical Laboratory. DCF transmits on 77.5kHz from Mainflingen, near Frankfurt/Main in Germany with signals derived from the Physikalish-Technische Bundesanstalt, Lab. Zeitenheit.
The 484.02 (MSF) and 484.03 (DCF) receivers are high performance units with dual crystal filters and dual ferrite antennas to provide omni-directional capability. The units are housed in robust IP65 rated cases suitable for protected external mounting.
In theory the signals are receivable at a range in excess of 1000km from the transmitter, subject to the effect of a wide range of variables such as time of day, atmospheric conditions and the degree of screening between the transmitter and receiver. In practice increasing levels of noise pollution, particularly from mobile radio systems, result in a reduction of reception reliability and 488HS3-GPS and 488hs3-GLONASS time synchronisation receiver systems are recommended for time and reliability critical applications.
