FM Radio Reception

~1min read

Range: In FM mono mode (single channel), the FM band range is generally between 40 and 48 kilometers (25 and 30 miles) and is slightly greater than the range offered by FM stereo mode. External factors may sometimes interfere with reception of the signal from an FM station even if the station is within 40 kilometers (25 miles). FM signal strength is inversely proportional to the distance between the transmitter and the receiver. FM signals travel in a straight line and have characteristics similar to light. For example, they are reflected by objects.

Fading and drifting: As the distance between your vehicle and the station transmitter increases, signals tend to fade or drift.

Noise and fluctuations: When signal interference is caused by buildings, mountains, or antenna position (this generally occurs at greater distances from the station transmitter), noise or fluctuations may occur.

You can reduce this noise by lowering the treble tone level.

Multipath reception: Due to the reflective characteristics of FM signals, direct and reflected signals reach the receiver at the same time. The signals may cancel each other out and cause momentary distortion or loss of sound.
