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.
WWVB Module : For receiving time signals from the transmitter at
Colorado, USA. Reception possible throughout the 48 contiguous
states of the USA and much of Canada.
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.
