Since the Brazilian government adopted legislation allowing AM stations to migrate to FM, the medium-wave spectrum has become more favorable for the propagation of radio signals from other countries—specifically, in the case of southern Brazil, from Argentina, Paraguay, and Uruguay. As night falls, the radio dial in Porto Alegre fills with Spanish-speaking broadcasts. And any receiver can pick up these transmissions—and I mean *any* receiver, including this Sharp SG-220 all-in-one stereo system from the late 1970s.

As long as the neighbors don’t turn on any electrical appliances (which cause terrible interference), it’s possible to tune in perfectly to stations from those countries. In this video, I take a quick tour of the stereo system’s dial so you can get an idea of ??what I’m talking about, including an Illustrated Radio Listening Report.
