Just because it takes a few clicks from the article to get there, Oona Raisanen (aka windytan) did this originally.

If this interests you at all highly recommend you check out her blog.

Thanks! I never found her blog with all my quacks and googles on SDR keywords.

>quacks

I've never heard this but I hope it catches on :)

Haha, it took me half a day to realize what it refers to.

Oona has super interesting projects in the blog. Can highly recommend too!

Pure curiosity but do you know what software was used to generate the spectrogram in that poster?

The color scale used in it really looks like the old-school cathode ray oscilloscope displays.

edit: found it, windytan actually mentioned it in the blog page. It was done using 'baudline'. (http://baudline.com/)

Sometimes it's a pain in the ass to get it dialed in but once you do it's hard to beat.

One issue of the Finnish Skrolli magazine actually came with a poster with that picture. :)

She is one of my favorite hackers and role models. I always learn something new and fascinating when I read one her posts.

Cool! She’s got more music and a bunch of cool experiments/demos on her YouTube channel: https://www.youtube.com/user/windnyan
