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
2. Interference from Engine Components
3. Interference from other components
