The following information may help to explain differences between car radio reception and radio
reception in the home.
Signal sending
FM waves do not follow the earth's surface and do not bounce against the atmosphere as AM waves do.
Cross modulation
When receiving a weak signal in the vicinity of another, stronger signal, both stations may be received
simultaneously.
Weak reception (fading)
Because of the limited range of FM senders and the way FM waves spread, this problem usually occurs
with FM reception.
Mountains or similar obstacles can sometimes cause disturbances.
