You might think amateur radio would be the cleanest, best-behaved place in the world to be, but you would be wrong. There are bad actors out there on HF radio but they tend to stick to the same corners of the spectrum. I would suppose that by staying out of the travelled portions of radio, they avoid most of the opprobrium they would get from the larger community. This also serves them as kooks tend to seek each other out.
14.313Mhz is a popular frequency for conspiracy theory whack jobs. They always put on a great show. What makes it interesting is when competing whack jobs get onto opposite sides of whatever phantasmic kookery is the topic du jour. I need to remember to record some of these. And bring some popcorn….
