The future is software.  The HDSDR hardware is works well.  There
might be incremental changes, to say take advantage in a new A/D chip
or whatever but the software lags the current state of the art by more
than a decade.

The current state of the SDR art is NOT in the ham community.
Government and academics are leading.  For example we should not be
simply trying to implement a 20 year old HF radio in software.  We
should not be sending the audio feed from an SDR to a digital mode
decoding program.  No, our SDR should be recording a searchable
transcript of _everything_ on the _entire_ band and allowing us to
search that transcript and instantly tune to a call sign the SDR
detected minutes ago.

We need to stop thinking like Henry Ford's customer.  Remember Mr.
Ford's quote "If I had asked my customers what they wanted they would
have told me - A faster horse."

The future of SDR is not  a faster horse.   Whatever it is, it will
allow us to do things be can't do now

What about synthetic aperture antenna built from HF radios that are
miles apart?  Radio astronomers do this by combining their data in
phase.  There are a thousand things like this and it's all "just
software".

Optical astronomers can "adptive optics" where they warp the optics to
counter the effects of the atmosphere.  Could this be applied to
radio.  "warp" the transmitted signal to that after distortion it
souds clean at the recieving end.  Possable the SDR could monitor a
sub carrier

There is more to be done going forward then has been done with radio
in the last 100 years.
