|All Those Linux Distrobutions|
Their description says that it is a remastered version of Ubuntu Linux. If you check out the website you can see that there is a good amount of Ham Radio Software packed into it. It does not take a huge amount of disk space and requires at least a 1Ghz Processor as well as 1gb of memory. So all the computers built today can easily handle that. So it is definitely worth the time to check it out.
If you are looking for various linux software programs for Ham Radio I would suggest looking at www.dxzone.com . You can click on this link Ham Radio Programs For Linux Platform to see a variety of different linux programs that may be of some use. Otherwise if you download the current Ubuntu Distribution you can run the live cd or install it on your computer. Then you can see what Ham Radio Linux programs are available or what other programs you can download. Hey it's free due to being open source.
Hope this video from a couple of years ago give some ideas as to what programs are out there for Ham Radio.
