POTENTIAL SOURCES OF INTERFERENCE
With all Meteotime weather stations, we should take measures to provide best possible radio recep-
tion. DCF is a long wave station with a broad reach (approximately 1500 km). However, as with a long
wave radio station, interference may occur which is often caused by the following influences:
• In buildings with lots of concrete, metal parts, and the electrical equipment you may get
reception problems (for example, in shopping centers and at exhibitions).
• Electronic equipment such as TVs, computers, household machines, etc., or transformers,
power lines, radio transmitters, and trains are potential sources of interference.
• Atmospheric influences might affect the radio waves.
• The distance from the station, and also the geographic conditions (mountains, etc.) also
affect the reception. Due to their great distance from the station, areas like Southern Italy
or Northern Scandinavia are critical.
• So-called (dead-spots) which make reception impossible can appear everywhere
• There is less interference in rural area than in heavily built-up urban ones.
• On principle at night the sources of interference are less active, consequently reception is
better than during the day.
• Weak batteries in the device will lower the quality of reception.
DATA TRANSFER
METEOTIME sends the data during precisely defined time slots in accordance with UTC. (UTC, i.e. for
Central Europe during the winter UTC+1, during the summer UTC+2; for Great Britain and Portugal
during the winter UTC, during the summer UTC+1)

the 30 additional regions
In the event that the reception during the above time slots is completely or at times interfered with or
has broken down, these forecasts, or parts of them, will be missing.
The package comes with a base station, which is the Meteotime weather station, and one 3-channel
wireless outdoor sensor (thermometer). This Meteotime weather station has equipped a thermometer
sensor to measure the indoor temperature, and uses the wireless outdoor sensor to measure the
outdoor temperature.
