1) AFAIK, The E4000 has a limited output bandwidth, in the range of 8
MHz max usable IIRC. It's designed for DVB/TV applications and they
don't need more so the IF filters available don't go above that.

2) You still need to pipe all those samples to the PC somehow, this
will raises the price of all of this way above the original 20 USD and
make it a much bulkier setup.
