Software-Defined Radio: the Apple I of Broadcast?
benfrog writes "A company called Per Vices has introduced software-defined radio gear that Ars Technica is comparing to the Apple I. Why? Because software radio can broadcast and receive nearly any radio signal on nearly any frequency at the same time, and thus could 'revolutionize wireless.' The Per Vices Phi is one of the first devices aimed at the mass hobbyist market to take advantage of this technology."
It's receive only, and the quality isn't magic by any means; but you can get an RTL2832-based DVB-T dongle for ~$20 and be on your merry way.
(And, indeed, this does seem to have spurred greater interest among people who weren't in for a USRP; but were interested. The fact that SDR involves substantially more nontrivial math than many arduino projects probably limits the mass appeal some, though.)
