Open-source Radio Revolution

It looks like government control of the airwaves is about to become a much harder prospect. The Universal Software Radio Peripheral, or USRP, is an open-source device that can do virtually anything that involves the reception and transmission of radio signals – which means not just radio like you have in the kitchen over breakfast, but all kinds of TV, cell-phone signal, radar…pretty much any broadcast technology at all. All thanks to the magic of general purpose computing and some hardware trickery.
