I am reminded of one case when I *did* hear an unexpected AM 
radio broadcast. Years ago I was fiddling with a 16mm projector, 
where a light shines through the soundtrack onto a reflective 
drum, and reflects into a photocell. Well, the broadcast from a 
local AM station was distinctly, though faintly, audible through 
the loudspeaker. I never did find out what the mechanism was.
