Thanks Brent, The Raspberry Pi is popular and it might be less rf noisy than a full size punchbox! It certainly doesn't have as much electronics in it and it has far less IO for sure. Switching to the Pi might negate a significant amount of noise generated in the computer and radiated by its I/O cables. I don't have a Pi, but there is one in my future::> They're still getting cheaper::> I'm not sure the Pi can do high speed USB 2.0 due to power limitations and its ability to shed heat. The SDR will not work unless full speed USB 2.0 is used, they wann you many times about this--and it's why I bought a quality USB extender cable that fell well short of the rated cable length of 16.5 feet for full speed USB 2.0.
