Manoj Kumar, Devendra Purohit, Marten Christophe, and others at technosa...@gmail.com,
A humble request for you to get some perspective: Running a business costs money: Parts, supplies, equipment, manufacturing, assembly, testing, employees, export compliance, future developments. Maybe the developers like to have a job and eat food? The price you want to pay does not cover the true cost of a USRP. Matt is not the enemy, and using the mailing list to publicly humiliate him into giving you a free USRP is not really an appropriate list topic. If you are angry at the "man" and the big cooperations stepping on the little guy; you are seriously barking up the wrong tree. You can find lots of other projects, or great ways to contribute without radio hardware. I created most of gnuradio-companion with my own laptop and without any radio hardware or test equipment. Maybe you can get a signal capture from someone and work on a demodulator; or come up with a new modulator that works in simulation (as others have suggested). When the time comes to test the software, perhaps you can borrow some hardware (maybe a USRP) from another university.
