I recently got my hands on a RTL-SDR (I’m currently using NooElec SmarTEE), short for Software Defined Radio. Basically a tool which lets you hook up your PC to an external antenna, in layman’s term. And oh boy, the things you can do with it is beyond words, literally. Radio waves are not sent with words… Bad joke. Sorry. First, I did what everyone does at the beginning: FM Radio. Then Air Traffic Control. Then more random gibberish. And then finally, NOAA 19 weather satellite! NOAA 19: An old weather satellite that has some cool cameras that enables anyone with a SDR to get low quality realtime pictures of Earth.
