While I have not done this yet, there is supposedly software that allows
direct sampling down to DC.
Some of the devices have a hole in the coverage around 1200 MHz so watch
out. I think the RTL2832 is ok though.

Google DVB-T and RTL2832. I bought a device about some months ago for about
$20. It does actually work as advertised, though this one looks nicer than
the one I got. Apparently the guy who was writing the linux driver for these
(Antti Polisaari of Finland) noticed a feature that allowed it to be turned
into a broadband receiver. It can be commanded to output an 8 bit I/Q stream
at up to 2,000,000 (more actually) samples per second from 64MHz to around
1.7GHz. There is an article about them in the Jan 2013 QST. There's at least
one guy on ebay selling HF converters for them.

Has anyone played with this thing?

If you add a laptop, is the thing a complete radio? It seems to be far too
cheap to believe.
