Turn that ***** up. - matt0509, on 04/10/2009, -0/+14I've been building a ultra wideband transceiver for GNU radio for almost a year now. Not really sure why this is so suddenly news, but here's the actual site. http://gnuradio.org/trac
- SpaceRibs, on 04/10/2009, -0/+6Sounds like pirate radio is going to make a comeback.
- NikoKun, on 04/10/2009, -1/+6For a moment there I thought it read GNR... aka Galaxy News Radio... I've been playing too much Fallout 3 lately. @_@
- MuadDave, on 04/10/2009, -0/+5I love the idea of what they've accomplished, but I've tried to use their software, and their doxygen-generated documentation is so limited that you really have to be a code contributor to know what the functions do. I tried to use their docs for learning about DSP, but found it unusable - I guess if you're an expert you can make heads or tails of it.
- lead2thehead, on 04/10/2009, -0/+4This will open up a whole new world of RF hacking. The FCC has laws about which frequencies you're allowed to listen to and broadcast on. Take cell phones.... you can't even buy a radio that is capable of receiving those frequencies without a special FCC license. The hardware is physically capable of receiving them, but the firmware won't allow it. This would allow you to bypass those restrictions.
- Otto, on 04/10/2009, -0/+4HAM operators have been hacking their hardware to receive those sorts of frequencies for decades. There's how-to guides for most of them out there. Google, bro.
- cosequin, on 04/11/2009, -0/+3There's a great interview with eric blossom here:
http://interviews.slashdot.org/interviews/02/09/27 ...
it's official GNU software, which means it will be very high quality once it's finally released. At least all of the command-line tools are.
For some things (like listening in on wireless phones, which are unencrypted and traveling through the air like radio waves) there is nothing out there to buy, it's all illegal sell such a device. But to build one is a gray area, imho. - Ohnodonho, on 04/10/2009, -1/+4Well turn it off and stop complaining.
I love that almost 100% of your comments are negative. - jftitan, on 04/10/2009, -0/+2new to me, and I'm bookmarking it.
- UKsHaDoW, on 04/10/2009, -0/+2I came across this while looking for some spectral analysis software for linux ages ago.
- orias6891, on 04/10/2009, -0/+2Unrelated to the article, but this brought back memories of LUG radio (http://lugradio.org/episodes/). Awesome linux podcast.
- fyngyrz, on 04/10/2009, -1/+3Not to mention that their idea of "affordable" is $700 for the hardware you need.
For that kind of money, you can buy a very nice receiver or decent transceiver. Which will "just work", without you having to jump through the *many* hoops the hodge-podge of C++, Python, wxPython and more these guys have put together. Presuming it will compile for your particular system, which isn't a given, either.
It's a typical open source project -- incomplete, poorly designed, costs out of control, built with inappropriate s/w tech, and having absolutely no polish whatsoever. After ten years! - Culyt, on 04/11/2009, -0/+1Saw this a while back.
I would be interested to see 801.11X implemented in it, I'm sure there are some cool wifi hack projects that could be done with a software wifi access point. Also with one decent radio you could support most future wifi standards without upgrading hardware, although my knowledge about that is limited. - Culyt, on 04/11/2009, -0/+1In reply to myself:
"Some code has been released which can send and receive 802.11b at 1 mbps. However, USB 2.0 is too slow to support two way 802.11 interactions. A new version of the USRP is under development which will have a faster interface which may be 802.11 capable.
Currently, no simply due to the latencies required do not allow for round trip processing of packets over the USB 2.0 interface on the USRP. This might get quicker with the inclusion of inband signaling in an upcoming release, but the round trip delay plus processing time probably won't work too well. "

http://www.gplpedia.com/Softwares/demos/BlueZ.html - kd1s, on 04/11/2009, -0/+1Interesting prospect but until the hardware gets super cheap, E.g. < $300 you're not going to see more widespread adoption other than engineering firms.
The Ettus platform is interesting, but to get something that plays in the mobile bandwidths you're looking at $1,000. They do have some schematics for USRP2 on the dedected.org website but no parts list, no interconnect detail, etc.
It's just going to be a toy for some time. - mikembley, on 04/10/2009, -0/+1yarrrrr
http://www.cristgaming.com/pirate.swf - drag, on 04/12/2009, -0/+1With this device you can do everything from capturing HD broadcasts to hacking rdif tags. With software defined radios you have maximum control over the radio signals your sending. It's not a tool for normal folks.. you have to be really interested in hacking the radio spectrum to get what this device is about.
- nutkin, on 04/11/2009, -0/+1Matt Ettus?
- fyngyrz, on 04/12/2009, -0/+1Yeah, you let me know when I can buy the hardware and install the software that lets me do all that.
What? You say I have to *write* the software?
(laughing my ass off)
There is no software. There's just a bunch of *really* crappy source code that does a little thing or two here or there, and no unified or planned GUI. It's just junkware. - drag, on 04/12/2009, -0/+1In order to play around with this thing legally your probably going to need FCC licenses at minimum.
This is not for setting up a neighborhood FM station in your basement.. this is for real research and development as well as all sorts of very special purpose devices. Not for the faint of heart. - astyguy, on 04/14/2009, -0/+1why do I need this as I am quite happy with DAB
- kd1s, on 04/12/2009, -0/+1I have both my amateur and commercial licenses.
- digdug2020, on 04/11/2009, -0/+0Not really, this is a wide band radio receive/transmit. FM/AM stations are over a very limited span. GNU radio covers far more than that, but it doesn't exactly tell you how to put up an amplifier and antenna necessary for pirate radio, and is way more than you need to create a basic radio station.
- drag, on 04/12/2009, -1/+1> For that kind of money, you can buy a very nice receiver or decent transceiver.
Haha. If you think you can go and buy a tranceiver for 700 bucks that can do more then a tiny fraction of what software defined radios can do your completely delusional and have no clue what your talking about.
When was the last time somebody offered a commercial product that could do everything from tracking cell phones through a mall, to hacking rdif tags, to doing frame captures from over the air HDTV broadcasts? Try getting something else to do that for 700 dollars. - inactive, on 04/11/2009, -2/+1All hardware problems into software problems? That makes absolutely no sense.
- JonForTheWin, on 04/10/2009, -4/+1The Digg bar sucks.
@Ohnodonho
No you don't, you're a liar. - inactive, on 04/10/2009, -10/+1the digg bar sucks
