Software engineer and perpetural hacker Balint Seeber presented this talk at the Ruxcon 2011 conference held November 19-20, 2011 in Melbourne, AU. Balint presents those unfamiliar with SDR with the basics of the hardware and software you’ll need and highlights what’s out there in the lesser known areas of the RF spectrum. He explains some of his experiments with SDR with particular attention to satellite monitoring including analysis tricks from the RF level down to understanding the raw data.

Balint runs the spench.net website where you can read about his various RF and SDR projects.
