Digital Signals
- unwind 4y agoMeta: 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.

- TrackerFF 4y agoFor 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 https://www.sigidwiki.com/wiki/THOR)
- kkoncevicius 4y ago> When you play the sound, the start is at the bottom of the image, and then moves upwards (kind of like Guitar Hero) In this case Y-axis is time, no?
- ScottEvtuch 4y agoThat 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?
- int3rlop3r 4y agoPlay all of them together! (:
- rahen 4y agoListening to those samples, I initially thought this was a new album from Autechre.
- IIAOPSW 4y agoMy favorite track has to be Russian enigma.
- nforgerit 4y agoLove it. Now I just need to find some cereals that put whistles in their boxes.
- greggsy 4y agoRelated, there’s an awesome tool [1] created for the SDR crowd for decoding captures of 433mhz signals, which really deserves an award for open source design and is a genuine public service. I’ve used this to identify and reverse engineer generic thermometers, which saved me a heap of dough paying for name-brand gear. [1] https://triq.org/ https://triq.org/
