AM (MW, LW) reception
AM broadcasts can be received at
greater distances than FM broadcasts.
This is because AM radio waves are
transmitted at low frequencies. 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
obstructions so that they can provide
better signal coverage.

FM radio station
OJF045309L
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 easily 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.
