I don't see any reason not to post the schematic, the hardware doesn't really include anything that hasn't been done before. I do use a proprietary technique to reduce (and nearly eliminate) spurs due to DDS artifacts, but the value in the hardware is that I've combined everything in a small, well-constructed package. I'm using AD9834 DDS chips. Looked at the Si57, but it's very pricey.
