Frank, Please excuse my pedestrian approach. I am trying to visualize the overall system including how it will be developed and maintained. Your very helpful comments indicate that in the next version, the radio will consist of three discrete components, which communicate via hardware and/or

Jim, I think you have given an excellent and useful breakdown of what kind of things will be in the Core component. It will itself be a rather complex set of sub-components, that will be linked together by different kinds of interfaces than the firewire that links it to the hardware, and the

Frank, Thank you for these very useful details. I need to look into John's work a bit. I realize that the DttSP libraries are c libraries and run on either platform. It is all the other code in PowerSDR that is not Console code, and is written now in c#, that I am wondering about. What will

snip There are companies that exist to sell platforms for development (like Spectrum Signal Processing, Nallatech, etc.) and their platforms are priced accordingly. A $15,000 hardware development platform isn't all that expensive in the context of a $100K seat license for all the FPGA tools
