AM(Amplitude Modulation)
CHARACTERISTICS
Station mixing
AM signals bend around such things as
buildings or mountains and bounce off the
ionosphere. Therefore, they can reach
longer distances than FM signals.
Because of this, two stations may some-
times be picked up on the same frequen-
cy at the same time.

FM (Frequency Modulation)
CHARACTERISTICS
An FM broadcast range is usually about
40—50km (25-30 miles) from the source.
Because of extra coding needed to break
the sound into two channels, stereo FM
has even less range than monaural (non-
stereo) FM.

Signals from an FM transmitter are similar
to beams of light because they do not
bend around corners, but they do reflect.
Unlike AM signals, FM signals cannot
travel beyond the horizon. Therefore, FM
station cannot be received at the great
distances possible with AM reception.
Atmospheric conditions can also affect FM
reception. High humidity will cause poor
reception. However, cloudy days may pro-
vide better reception than clear days.
