I agree!

I'd much rather "embed" something like a mini/nano/pico-ITX board and
do the DSP/control there with open source tools.

A small command line only distro of Linux running from flash, with
c/c++ code doing DSP/control will give you the performance of ALL
IF-DSP based radios available today, IMHO.  DttSP or SharpDSP2.1/Mono
will run with no problem on these.

Yeah, yeah, yeah, I know "it ain't necessarily a low power
solution"... but I can live with that.  A lot of guys use laptops for
portable operation these days and they have similar power requirements
so I don't see it as a big issue.

For the QS1R, QS1RServer runs perfectly on this board:
<http://www.logicsupply.com/products/boxd945gclf2> for any rate you'd
want up to 2 MSPS - try that with some of the embedded DSPs in the
same price range...  Or if you are happy with 250 kHz spans, embed a
dinky pico-ITX board <http://www.logicsupply.com/products/px10000g>
which is barely the size of a credit card.
