FM radio works the equal way that AM radio works. The distinction is in how the service wave is modulated, or altered. With AM radio, the amplitude, or usual strength, of the sign is diverse to comprise the sound information.

So is FM better than AM ?well maybe...

In addition FM waves supply higher sound reproduction. With an FM broadcast, moderate modifications in amplitude do not count at all -- because the audio sign is conveyed thru modifications in frequency, the FM receiver can simply skip modifications in amplitude. The result: higher sound reproduction.

So why would you want to use AM radio ?(if you find some vintage one).

Compared to FM or digital transmissions, AM transmissions are extra highly-priced to transmit due to the necessity of having to transmit a excessive strength service wave to overcome floor losses, and the massive antenna radiators required at the low broadcast frequencies, however can be despatched over lengthy distances by the ionosphere.

AM radios are not used as often these days as FM ...

Gone are the days of the 'warm, soothing AM stereo' sound. Music has all however left the AM band, with FM (Frequency Modulation) imparting a ways most useful listening experience, in phrases of interference rejection, stereo signal, and noise floor.
