Radio interference complaints may be caused by either external factors, vehicle components, or radio system failure. Therefore, a clear differentiation
must be made between these areas of possible problems.
Below is a troubleshooting guide for radio reception interference:
1.
Interference due to external factors.
Radio reception could be influenced by the following factors:
-
landscape (mountains, trees, poles, buildings)
-
reflection of radio waves (multiple reception)
-
weak broadcasting stations
-
Stations with changing broadcasting power
-
transmitter frequency not adjusted precisely in radio
-
transmitter or frequency overlap (large signal)
-
weather clouds (high pressure area)
-
interference could be considerably stronger for stereo reception than for mono reception
-
strongly changing reception signals
