SCA FM Receivers
We've all heard stories or seen movies about people who receive--or think they receive--radio signals through their fillings (it's debatable whether or not this has ever happened). The underlying point here (besides giving the paranoid grist for their mill) is that radio waves are around us all the time. Radio waves are part of the technology that makes things possible like microwave ovens, remote controls, cellular phones, and of course radio itself. But these radio waves are useless without the ability to convert them into a different form. In the case of FM radio, that means the radio waves need to be converted into whatever was broadcast by the station.
FM radio dates back to the 1940s, but it didn't reach its zenith until the late 1960s/early 1970s. The explosion in popularity in rock music, in addition to more ornate recordings, made higher fidelity stereo broadcasts not only desirable, but also necessary. This is why, by and large, FM radio today is mostly music programming, and why AM has more talk radio (there are numerous exceptions to this, but it's a good general rule).
An FM receiver does just what its name suggests: it receives the signal. But the receiver does more than that; it also decodes, interprets, and sometimes even amplifies the signal so you can listen to it. And if you want to listen to SCA transmissions (i.e., subcarrier transmission), you can't do so without a special receiver. Subcarrier transmissions are bundled with some FM broadcasts in the leftover bandwidth from the primary signal.
