FYI:Linux and Software Defined Radio

From: Rod 
------------------------------------------------------
Been during research lately into linux and ham radio support.
There have been more than few good linux distros with a ham focus over the  
years.
At least two puppies, a few ubuntu respins, etc.

Just found Kali Linux which seems to be picking were up Backtrack Linux  
left off.
Kali Linux has an SDR metapackage that is worth looking into.
It includes their own fork of Debian's gnuradio which updates to the  
latests sources. As well as GQRX which support several USB SDR dongles.
Including a $20 TV dongle that can be used as a broad spectrum scanner  
that can be used for all kinds of cool stuff.

While Kali Linux should be in any serious linux users toolkit, I'm not  
sure if a distro that runs as root by default is the best choice for some  
of my fellow hams. Especially the many who are xp refugees mourning the  
loss of their dead os. Though it has some good ideas for the start of a  
new HAM Shack OS.

=============================================================== From: "Alex Smith (K4RNT)" ------------------------------------------------------ I have an article in QST magazine about SDR, using a DVB-T dongle. However, I don't have the article in digital format, it's on the print edition that I just found while cleaning my bedroom. Hopefully I'll be able to scan it into the computer in the next couple weeks or so. I'd like to try out SDR. Cheers, and 73 de K4RNT " ' With the first link, the chain is forged.

=============================================================== From: "Alex Smith (K4RNT)" ------------------------------------------------------ Man, they're complaining a lot, sound a little like children. What do you expect for $50 in equipment, a bloody Icom shortwave receiver? This is interesting as a project, not as a commercial device. :P 73 de K4RNT " ' With the first link, the chain is forged.

=============================================================== From: Rod ------------------------------------------------------ Yeah I'm thinking of importing some to sell at hamfest along with the software needed to do all this. -- The unregulated free market is like Yog-Sothoth, a mythical being whose followers make bloody sacrifice to hasten its arrival to this world.

=============================================================== From: "Alex Smith (K4RNT)" ------------------------------------------------------ Anyone used this so far? I'd be interested in finding out how many bands are typically receivable on this type of equipment, HF and hopefully VHF/UHF as well. " ' With the first link, the chain is forged.

=============================================================== From: "Alex Smith (K4RNT)" ------------------------------------------------------ That would be awesome to set up as a wideband receiver. I'd probably just be tuning into HF to see how much traffic I can hear, and then also monitor VHF during severe weather to support SKYWARN and ARES operations. My main interest in ham radio is emergency communications and serving the public. When I lived in Rutherford County, I was active with both ARES and SKYWARN for middle Tennessee. I also provided communications manpower at the American Red Cross comm center in Murfreesboro during the April 7, 2006 tornado outbreak that crippled the city of Gallatin. I was a voice relay between east Tennessee counties and the NWS office in Nashville, when the repeater network lost a link between parts of the state. It was grueling, but I enjoyed the time, and I know my work saved lives in the process. Now that the cost of the hardware has dropped so much, and more software has become available, I think I'd like to get into this scene, and it's aweesome to see this kind of interest from a computer users group. :) 73 de K4RNT " ' With the first link, the chain is forged.
