FM - reasons for distortion
FM is affected by the electrical systems of nearby vehicles, especially those without suppression. The
distortion increases if the station is weak or poorly set. The FM reception is not as sensitive to electrical
disturbance as AM.
AM - reasons for distortion
AM reception is sensitive to electrical disturbances such as power lines, lightning, etc.

FM stereo reception
Stereo reception places very high demands on the signal quality which means the type of distortions
previously mentioned become even more obvious. The signal strength needs to be stronger for good
stereo reception and this limits the effective range of the sender.
We hope that this information proves to be useful and provides you with a better understanding of the
problems related to car radio reception.
