This week on The Amp Hour Chris Gammel’s guests are Michael Ossman, the guy behind a (cheaper, simpler than previous, highly capable) software defined radio system and Greg Charvat, the guy behind a coffee can-based synthetic aperture radar system that uses your PC’s “sound card”. One of the most easy on the ears, friendly and interesting sharing between techies I’ve listened to in a good while.  For those interested in learning about SDR Michael has started a tutorial series.
