Q&A
Why is noise heard from the radio sometimes?
Radio signals are sent from the broadcasting station, received by antenna
and then enter the radio through the antenna amplier. The intensity of the
received signals depends on the following factors:
1. Too small power output of the broadcasting station (the transmission
distance and range of low﹣power radio broadcast are limited).
2. The position of the vehicle relative to the launch tower (the closer the
vehicle is to the launch tower, the stronger the signals are).
3. Atmospheric conditions (for example, a strong electromagnetic eld in
the atmosphere will disturb the signals).
4. Frequency band of the radio broadcast (FM or MW).
5. Ground conditions (for example, tall buildings, hills or surrounding
vehicles will disturb the FM signals, which makes the sound fade in and
out).
6. Obstacles between the launch tower and the vehicle.
