So, out in the world, there's tons of web-connected "SDRs", or Software-Defined Radio (Receiver), where you can listen to the radio spectrum as it comes into one part of the globe, and live-move your listening, meaning you can catch all sorts of near stuff by moving it. 
Here's a website of a bunch of them: websdr.org
Every once in a while, I look into the Internet Archive saving these, and I just have to give up. The main reason is disk space. Either you want ALL of it, or else you want others to keep cool stuff, send it in.

It is severely neat, and it would be great to have them going back years, but it moves into terabytes and terabytes of signal data, even with clever compression, and the result is ton of wasted space "just in case".
Much easier to wait for someone to make it their mission to capture neat radio stuff and upload it. Over time, people have uploaded all sorts of them to us. I hope they keep doing it.
But one day.... SDR will be worth the space.
