FM broadcasts are transmitted at high frequency and do not bend to followthe earth's surface. Because of this, FM broadcasts generally begin to fade at short distances from the station.Also, FM signals are easily affected by buildings, mountains, or other obstruc- tions. These can result in certain lis-tening conditions which might lead you to believe a problem exists with your radio. The following conditions arenormal and do not indicate radio trouble:
AM broadcasts can be received atgreater distances than FM broadcasts. This is because AM radio waves are transmitted at low frequency. Theselong, low frequency radio waves can follow the curvature of the earth rather than travelling straight out into theatmosphere. In addition, they curve around obstructions so that they can provide better signal coverage.
B750A02A-AAT STEREO SOUND SYSTEM How Car Audio Works
AM and FM radio signals are broad- cast from transmitter towers located around your city. They are intercepted by the radio antenna on your car. Thissignal is then received by the radio and sent to your car speakers. When a strong radio signal has reachedyour vehicle, the precise engineering of your audio system ensures high quality reproduction. However, in somecases the signal coming to your ve- hicle is not strong and clear. This can be due to factors such as the distancefrom the radio station, closeness of other strong radio stations or the pres- ence of buildings, bridges or otherlarge obstructions in the area.
