FM reception characteristics

A characteristic of transmitted signals is that lower frequencies

travel further. FM frequencies are much higher than AM’s

(similar to a ray of light): they won’t bend but they will reflect.

Often, they will be interrupted by tall buildings, mountains, etc.,

taking direct and indirect paths to your vehicle’s antenna. The

distance at which FM stations can be received satisfactorily is

usually not nearly as far as that which AM stations can be

received.

In weak signal or “fringe” reception areas, FM stations may

fade out completely, or fade in and out. When driving in weak

signal areas, such as near hills, through valleys or tunnels,

among tall buildings, etc., you may encounter unusual noise

interference. THIS IS NOT A TUNER PROBLEM. In this case,

you can only wait until you are in a better reception area, tune

to a stronger station, or reduce the treble level.

In general, FM has much better tonal quality than AM. However, FM

and FM stereo reception encounter several characteristic problems

not encountered with AM. FM is more difficult to receive than AM in a

moving vehicle. The following are explanatory notes on what to

expect from FM reception and on how to get satisfactory

performance.
