This can be due to factors, such as
the distance from the radio station,
closeness of other strong radio sta-
tions or the presence of buildings,
bridges or other large obstructions in
the area.
AM (MW, LW) reception
AM broadcasts can be received at
greater distances than FM broad-
casts. This is because AM radio
waves are transmitted at low fre-
quencies. These long, low frequency
radio waves can follow the curvature
of the earth rather than travelling
straight out into the atmosphere. In
addition, they curve around obstruc-
tions so that they can provide better
signal coverage.
FM radio station
FM broadcasts are transmitted at
high frequencies and do not bend to
follow the earth's surface. Because
of this, FM broadcasts generally
begin to fade at short distances from
the station. Also, FM signals are eas-
ily affected by buildings, mountains,
or other obstructions. These can
result in certain listening conditions
which might lead you to believe a
problem exists with your radio. The
following conditions are normal and
do not indicate radio trouble :
