Operating Tips for Audio
System
M Radio Reception
AM characteristics
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 sometimes be
picked up on the same frequency at the
same time.

FM characteristics
An FM broadcast range is usually about
40—50 km (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.
