    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/ http://baudline.com/)

      She makes a lot of use of baudline. https://www.youtube.com/watch?v=YGdg_VC9LDI https://www.youtube.com/watch?v=YGdg_VC9LDI Sometimes it's a pain in the ass to get it dialed in but once you do it's hard to beat.
