It has been an interesting several weeks here as the spats have played out surrounding s/w usage, development, creation, intellectual rights and so on.

Much of the story is far outside any expertise or knowledge that I may have. I am really excited about the advent of inexpensive and interesting hardware units coming forth, and I am eager to join the movement. That leaves us with the s/w issue, which seems--at least for one fascinating product-- to be in a state of flux.

So, hobbyist friends, I have a question that confirms my ignorance but your answers may enlighten many like me.

I have read here about the huge amount of time, love, sweat and toil that goes into creating sophisticated s/w for utilizing SDR hardware. The sophistication of some products I have seen, like SDR Console, certainly demonstrates a huge effort by extremely knowledgeable creators. I realize it takes rare and devoted talent to produce something on that order.

One particular unit sounds like it could fulfill many missions if all the capabilities could be harnessed with s/w, many of those capabilities of great utility in an academic environment, for hobby use, and in all kinds of signal analysis.

Would this type of software creation provide a challenging project for a group of EE/Computer Science students from some engineering schools? Could a class section of 30 bright young people, working under capable direction manage to produce such software? Perhaps it might have to be a multi-university effort, with each group working on
their particular segment.

There are so many factors involved, most of which I know not of. I realize the average young geek probably has no idea of what SDR Hardware users need. The learning aspect of such a project could be very powerful. They would have to understand the hardware, look at other s/w packages and identify what things can be improved upon. Then they would need to know, from people like you, what is needed to enable these promising little units to perform their "full magic".

I realize this is a very difficult proposal, but the youngsters could really learn some real world stuff, and more importantly to the faculty involved, there would be fantastic publication potential. ( Something like " Novel Software Development for SDR applications in Radio Astronomy". Of course many other applications could also be heralded.

The big roadblock I see is that most academic institutions like to make money off their efforts.

This is just a humble idea, from someone who wishes to learn more, and hopes for a brighter future in the SDR world.

I hope to hear your ideas, however different, on the subject.

Thank you, lets keep radio fun!

If they are bright as you say, its not a problem. It takes time and work like anything else. The trick is how licensing is handled by the University and that needs to be worked out from day one before writing one line of code.

I can only envisage enthusiastic amateurs within the educational institute, wanting to learn DSP, radio etc, to take on and complete such a project. Many institutions acquire income from IP deals, but I don't see something such as this as commercially viable.

All good points made. My aim is to possibly inspire anyone with academic affiliations in EE/CS areas to think about. Many schools have a Jr. or Sr. class course for special projects, directed research, etc. Some larger schools may have multiple sections (lots of minds and hands). It just seemed to me it would be a profound thing for the students, and something many people could benefit from. However, it is just another of my radio dreams.....

Go Va. Tech! I am glad they are involved in SDR. I wonder if a sdr manufacturer who had a good product lacking adequate s/w could donate a half-dozen units for interested universities? Now if we could just spur their arch-rivals into a SDR s/w development race!

Most probably that would turn out like a story told to me by a physics prof. He said he had gotten a very expensive vhf/uhf radio rx on a grant for some study.

Then he mentioned as an aside that it resided at his home.

My new sdr is due today. Lots to do to give it a good home.

Good listening, and screen watching!
