Doesn't the SDR-IQ use an AD6620 digital downconverter to reduce the
bandwidth to a few hundred kHz? I've never used it, but its block
diagram would appear to suggest so, plus it uses a FT245RL USB
interface which is limited to full speed USB (ie 12Mbit). If so,
that's not enough bandwidth for Tom's 10Mbit/sec signal.
