I imagine that nearly all of my readers are interested in radio in some shape or form, so I thought I would recommend a fun documentary that you can view on Netflix streaming called Resurrect Dead: The Mystery of the Toynbee Tiles. If you enjoy the world of crazy conspiracy theories, pirate radio, and solving a mystery, then you'll get a kick out of this one.
The subject is the odd "Toynbee tiles" which have mysteriously appeared on urban streets in many of the larger cities of the East Coast of the US since the early 1980s. The documentary follows a trio of gentlemen who are determined to track down the responsible party for these bizarre messages which have been implanted into the asphalt of many city streets. I don't want to give away much of the story, but there's a significant and critical bit of the story devoted to SWL and pirate radio, so I think a lot of you will get engrossed in the story based on that, not to mention the general oddness of the topic. As I mentioned, it's available for free if you have Netflix streaming, so put it in your Instant Queue for a watch soon.
