Meta: I think "RF" or "wireless" in the title would be warranted, this seems to be very much focused on radio communications. Obviously there's a lot of digital signalling going on in wires as well, so the distinction has merit in my opinion.

Also, it's a really impressively long list! Cool.

Edit: clarified first sentence.

For those looking at the waterfall images: Y-axis is time, X-axis is the frequency axis, colors are intensity. Jus a spectrogram that's been rotated 90 degrees to the left.

When you play the sound, the start is at the bottom of the image, and then moves upwards (kind of like Guitar Hero). Some of them can be quite musical, like the THOR (https://www.sigidwiki.com/wiki/THOR)

In this case Y-axis is time, no?

That sounds backwards to me. Don't you mean Y axis is time and X axis is frequency? Otherwise how could it play from bottom to top?
