Even though both popular in their own right, A.M. and F.M. radio differ in the method they send information over the airwaves. Amplitude Modulation (A.M.) alters the amplitude of the carrier frequency while Frequency Modulation (F.M.) alters the carrier’s frequency to convey information. Even though A.M. radio is easily distorted by weather conditions, man-made noises and tall buildings, the waves can travel a larger distance than F.M. waves, which may drop at approximately 50 miles from the station. Because A.M. radio broadcasts to a single audio channel, stereo sound isn’t feasible. This is also why there are more talk shows broadcasting from this platform. F.M. requires more bandwidth and has a more complex technology, enabling it to broadcast to two information channels simultaneously. Because F.M. radio has full stereo sound capability it’s ideal for music, hence its many music stations. When it comes to age, A.M. wins. The first A.M. broadcast, done by inventor Reginald Fessenden, occurred in 1906. F.M. radio was invented by Edwin Armstrong in 1933. As for popularity, F.M. radio wins. It gives listeners a static-free experience and provides quality sound and fidelity. Worldwide there are more F.M. radio stations than A.M. radio stations.

The quality of music you’ll receive from satellite radio is almost as good as the quality of a CD due to its digital signal.

Just how is it possible to get all of those stations with clear quality over so many miles? Rather than normal radio towers, satellite radio signals are digital and broadcast over a geostationary satellite, which allows them to reach cross-country.
