8.2 Connecting a Radio Time receiver
The clock has been designed for, and tested with our Radio Frequency
Time (RFT) Receiver Modules. (available separately from PV Electronics).
DCF Module:
For receiving time signals from transmitter at Frankfurt,
Germany. Reception is possible within a 2000Km radius of Frankfurt.
MSF Module
: For receiving time signals from the transmitter at Anthorn,
UK. Reception is possible within the UK, Eire, Northern France, and
Norway.
Please note:
1. The long wave signals propagate further at night, so the clock is
configured by default to synchronize at 2am.
2. Suitable Power Supplies: If using a switching power supply, it must
have an earth connection. Cheap Chinese switching adapters cause too
much interference and will not work. Alternatively use an old-fashioned
transformer type AC to DC adapter.
3. The time signals are intended that a receiving clock may collect time
data intermittently. The signal strength and fidelity is not like a 'TV
Signal', where one can get a perfect signal any time at will.
