1\. Port [**AMRAD Charleston**](http://amrad.org/projects/charleston_sdr/) FPGA loads from Digilent Nexys2 to the Xilinx Spartan3 dev board 2\. See if [**nexsys2prog**](http://plausible.org/andy/nexys2prog.tar.gz) can be adapted to support these boards and allow [**UrJTAG**](http://packages.debian.org/squeeze/urjtag) to work. 3\. Try to mimic a USRP only using AMRAD Charleston receiver boards. (Or audio ADC.) 4\. Look into [**VITA Radio Transport (VRT) protocol**](http://www.digitalif.org/) support 5\. Make use of the Ethernet port, possibly mimic a USRP2. [Category:FPGAWorkshop](Category:FPGAWorkshop "wikilink")
