This 1971 training film is pretty good. I like how they break the RF circuitry into just four components, then describe the AM receiver stage by stage. The way they handle diode (envelope) detection is exactly right. But their description of how mixing moves the incoming signal from the broadcast band to the IF is overly simple, and sort of just repeats the hetrodyne story from music. Real mixing is, of course, more complicated than that, but too complicated for a 15 minute film.
