The proven time keeping method in Germany and neighboring European countries:
From radio station "DCF-77" in Frankfurt/Main, the time signal is continuously transmitted and received within a radius of about 1,000 km. The external DCF receiver forwards the signal to the clock for synchronization.
- Orientation to the radio station in Mainflingen near Frankfurt is necessary
- Unfortunately interference-prone 77.5 kHz long-wave transmission, therefore reliable synchronization only at night hours
- During synchronization the Nixie tubes should be switched off (can be set-up in the options menu of the clocks)
- Central European Time (CET) is transmitted with automatic switching between DST and Non-DST
- Can be used in Germany and the neighboring European countries
- Can not be used with the Strawberry Clock
The wireless way of time keeping, specially with multiple clocks:
The data sent by the GPS satellite system is received (similar to the car's navigation system) and converted into a 433 MHz signal, then transmitted intermittently and received from ASK modules which are either fitted into Mr.Nixie clocks or externally connected to the PVelectronics clocks.
- Place the Wireless transmitter on a window frame with a clear view to the horizont
- Wall outlet for powering the Wireless transmitter necessary
- 433 MHz signal strenght up to 20 m indoor
- Every clock must be equipped with an internal (Mr.Nixie) or external (PVelectronics) ASK module
- One Wireless transmitter can be received by any number of clocks
- World time (UTC) is transmitted, which means that the clocks have to be configured once for the corresponding time zone and need to be set between DST and Non-DST twice a year by pressing a button
- Can be used worldwide, but specially intended for Export
These wireless components consist of the following devices
1.: A wireless GPS receiver with USB power supply for placement on a window frame.
2.: An ASK module (internal or external) for fitting into or connection to the clock.
If you want to use Wireless GPS synchronization for the first time, we recommend to order a
Wireless Set 3 (for Mr.Nixie clocks) or a
Wireless Set 1 (for PVelectronics clocks), as all necessary components are already included. Later, to expand to every new clock, you only need an internal or external ASK module.
See here a video of the very first evaluation sample of the Wireless Set.
