Reception Form of AM/FM Car Audio
-
VHF channels on FM will pass through the
ionosphere directly without reflection, but
once they hit high mountains, high-rise
buildings and other barriers, they will
produce reflection.
-
FM spreading distance is usually about
40~50 kilometers. It will become shorter
when stereo signals are transmitted.
-
The radio is far away from the broadcasting
station, so the signals are too weak to be
received. As a result, the radio will only
receive noises.
-
When the car is driven between the areas to
receive two strong stations with a close
signal frequency at the same time, the radio
may lose sound suddenly or produce noise
interference.
