radio programs at SW.
FM (frequency modulation) called FM radio, the radio is a kind of ultrashort wave. Its characteristic is the sound
qualty is clear, sound reduction degree is high, can dual channel stereo transmission, but the propagation dis-
tance is shorter, more suitable for the spread of close, general city will choose FM radio frequency
MW (medium-wave/amplitude modulated) medium wave radio is commonly used in city broadcasting, sound prop-
agation is far more than FM, but much closer than short wave.
Q:MW AND AM ARE THE SAME?
