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.

LART. 250 MIPS under one Watt. Free hardware design files.
