I suspect you'll find Tom is a very practical performance-oriented
engineer.  He's probably agnostic about what's inside the box as long
as better performance is demonstrated.  The problem with the QSD SDRs
so far is that better performance has NOT been demonstrated (not to
mention IMHO an unfriendly user interface for most contesters...but
that's another discussion).

Perhaps direct-sampling SDRs will be different, but I believe the jury
is still out.  Show us via independent measurements that any radio is
demonstrably better and I bet Tom will become a "believer".
