band, your radio may tune in the
second station until the original
signal can be picked up again.
AM Transmissions
Fading - AM broadcasts are
reflected by the upper atmosphere,
especially at night. These reflected
signals can interfere with those
received directly from the radio
station, causing the radio station to
sound alternately strong and weak.
Station interference - When a
reflected signal and a signal
received directly from a radio station
are very nearly the same frequency,
they can interfere with each other,
making it difficult to hear the
broadcast.
Static - AM is easily affected by
external sources of electrical noise,
such as high tension power lines,
lightning, or electrical motors. This
results in static.
