I think you're exactly right, Jack. There is no reason why we shouldn't co-opt some other command set and implement it such that a SR might talk just the same as something else, much less of an uphill battle having the radios supported. Anybody have a feel for one or other that is more well documented? I'm mostly familiar with the Elecraft/Kenwood command set. As came up at FDIM about the DSP residing someplace else (HPSDR--future) than a PC. Thats a large jump, but, I think it's worth watching what others are doing. I think initially it may just be providing a way to control the radios in a familiar manner with familiar software.
