One thought is to make up a board with a lot more testpoints, like this.
I had a picture of a board design here before, but I think I've since misplaced that file. I'll try to remember to check around for it.This design is for a temporary two-layer board that I would use only to get the design and development effort back on track. Once I'd resolved the FPGA programming issues, I'd go back to a four-layer design with a lot fewer testpoints.
But if you're one of those impatient folks who wants to play with a software-defined radio RIGHT NOW then you should check out these links, many of which describe projects that are much further along than my board.
