Radio frequency information RADIO FREQUENCY INFORMATION The Federal Communications Commission (FCC) and the Canadian Radio and Telecommunications Communications (CRTC) establish the frequencies AM and FM stations may use for their broadcasts. Allowable frequencies are: AM 530, 540-1600, 1610 kHz steps FM 87.9, 88.1-107.1, 107.9 Mhz steps Not all frequencies are used in a given area. RADIO RECEPTION FACTORS Three factors can affect radio reception: • Distance/strength. The further an FM station travels, the weaker it is. The listenable range of the average FM station is approximately 40 km (24 miles). This range can be affected by "signal modulation." Signal modulation is a process radio stations use to increase their strength/volume relative to other stations. • Terrain. Hills, mountains and tall buildings between your vehicle's antenna and the radio station signal can cause FM reception problems. Static can be caused on AM stations by power lines, electric fences, traffic lights and thunderstorms. Moving away from an interfering structure (out of its "shadow") returns your reception to normal. • Station overload. Weak stations are sometimes captured by stronger stations when you pass a broadcast tower. A stronger station may temporarily overtake a weaker station and play while the weak station frequency is displayed. The audio system automatically switches to single channel reception if it will improve the reception of a station normally received in stereo. 19
