GNU Software Radio Opens an Unseen World

The Universal Software Radio Peripheral (USRP) project is an open-source software radio system that can grab and decode anything: GPS, FM radio, HDTV, and even the signals sent by garage door openers. Like a radio Lego set, you simply point the software and antenna at a source and it begins grabbing everything within that band. You can then modify the incoming stream via software, allowing you to control just about any stream without expensive hardware.
