Couple years ago I was driving down the highway and got within a few hundred meters of a guy who was no doubt shooting skip on CB (skipping the ionosphere to work hundreds of miles away). The signal was powerful enough that when he keyed on his taillights would almost shut off and I could hear him through the cassette adapter in my car.

I’ve heard it’s possible to anonymously fry people’s systems with annoyingly loud bass this way. Urban legend?

Back when modems were a thing, I spent some time living at a friend's house, and shortly after I moved my computer in I started hearing voices. Very faint, but the content was ominous fire and brimstone stuff. I thought I was losing my mind, but I hunted around and they were coming from the computer. Apparently the phone line was acting like an antenna and picking up some religious AM radio show, and playing it through the modem's speaker.

  I used to have that happen to my speakers picking up my university's radio station when they were powered on and nothing was playing.
