When I became interested in the Flex 6300 a couple of years ago, I knew nothing about the FPGA concept. (And as I am not an Engineer or a Computer Science major). I still know little. That said, I went in search of a tutorial that would serve as an introduction to the FPGA and an explanation as to why it has opened up this new world in Ham radio. There are many out there. And none are perfect for the Ham Op, but this one I found very useful. Maybe you will too?
