Cool stuff!<p>Also keep a close eye on the Opensource SatDump project. That's a group of (mostly ham, but not all of them) radio enthusiasts that are listening to all kind of science satellites. They managed to decode many of them.<p>They are far far beyond the old 137MHz analog NOAA stuff. Collecting crazy broadband from S- or X-band is no challenge for them.
I love Marks posts. They are always starting from absolute nothing and then just builds up everything, so you can replicate everything he does. It's absolutely amazing writing and very educational.
