Some time ago a community I was involved with developed a sudden infatuation with shortwave radios. Not broadcasting, just listening to the creepy shit you can get on them. Random broadcasts, the odd discovery of satellite telemetry, the vast, VAST quantities of freaky religious shit, and of course, Numbers Stations.
The very first day I played with shortwave I picked up a numbers station broadcasting in Spanish. Freakiest shit I’ve ever heard.
Anyway, the link today is a series of guides for beginner shortwave stuff. It’s not too bad at first: you just need a radio. But eventually you start thinking about putting up a bigger antenna, etc. Still, interesting.
