Hi all, To be specific to concern
1) Create your own RF front end boards > putting mixer and LO is a handy breadboard work.. tryout some good examples from Analog Devices and TI. To get additional gains put LNA or PA in series. Learn basic hardware designs. 2) Create your own digital/baseband board > Check out many thesis work who have developed demonstrating platforms. Adding to commercial front, check SP601/605 from Avnet. Check for the prices for sure!. Also check Spartan 3A 1800 DSP from Xilinx. 3) Write all the software for board in step (2) to control all the boards you create in step (1) > Not required. All the development boards are platform specific and the board developer supports BSP(Board support package). If you are building your board, you need to develop your own BSP. All the development board comes with BSP. A mere DMA transfers between PC and board is a 4 weeks of development activity. 4) Write all the host side software to interface software written in step (3) with GNU Radio > Platform independent drivers already address the issue. 5) Contribute all previous work to GNU Radio > No one says its personal development after posting at open source community developers 6) Stop complaining* > No one complains unless there is deviation against addressed. The capability and contribution you are talking about cannot be patchy work. Patchy work is needed to fix design bugs. Open source community would be interested to have proper solution rather patches.
