It's a USB device that's basically a all-band transceiver in software. So much for the HDTV broadcast flag :D


Plug it into your USB port, reconfigure/write some software and...voila!

receive/decode the band of your choice, whatever it might be: GPS, FM, HDTV, shortwave, celullar, radar, ...

If you want to transmit, you'll need to buy a daughterboard that covers the band of choice, but they're available over a pretty wide range of spectrum, from 2mhz to it looks about 3ghz.

Prices start at $550 for the base motherboard. Daughterboards vary from $75 to $275.

Supported OS's include

Linux (2.6 kernel, any distribution)
Mac OSX (PPC and Intel)
Windows XP/2000
NetBSD and FreeBSD

we did that more than 15 years ago....and the front end parts cost less than 15 bucks from antenna to sound card input....in fact I sent a working unit to another forumite maybe 6 months or so ago......our system operates to 6 ghz satellite bands...but the system could just as easily go to 14 ghz for another 3 bucks....

But not like this. This is new and scary/cool...

From the BoingBoing piece (http://www.boingboing.net/2006/06/05/gnu_radio_the_univer.html) on it :

Wired News has an excellent article on GNU Radio, a software-defined radio that can emulate practically any traditional radio just by changing the software. With the right GNU Radio hardware, the same machine can act as a digital TV receiver (try forcing the Broadcast Flag down a GNU Radio owner's throat!), a satellite radio receiver, an AM/FM tuner, an analog TV receiver, and a military radar installation. All at the same time.

GNU Radio can do cool and scary stuff that old special-purpose radios can't do, like tune in and record every FM radio show, or all the cellular traffic on a certain street corner. The GNU Radio software is free software, licensed under the GPL, so you can improve on it, tweak it, start a business based on it, and torque it, all without paying anyone or asking anyone's permission.

yes we can...our front ends will accept spread spectrum signals which are wider than wideband tv.....in all truthfulness, we designed it as the front end of a spectrum analyser to couple to a laptop computer. The audi0 card contains all the digital filtering etc that we need to process the intelligence from whatever r.f. signal we download...the only problem we encountered was the various non standard audio subcarriers from the tv signal, we had to build another $5 box addition for that.......
