Sources of Interference
Contents
The time code is transmitted in the longwave range by amplitude modulation, it can therefore be easily disturbed. The many sources of interference include atmospheric disturbances like thunderstorms on the way to the receiver. In case of thunderstorms near the location of the transmitter the transmission is stopped for the length of the storm. This may take up to several hours.
Interferences on the location of the receiver are mainly caused by motors, monitors, displays, corona discharges from high-voltage lines or switching contactors. The place for the antenna must therefore be selected with utmost care. Narrowband receivers are an alternative to suppress interferences.
Please note: Narrowband reception and accuracy exclude each other!!
