Sorry Helmut, but all things in the real world are discrete. ;-)

For certain practical reasons though, we deal with analog properties. But
then again, all information processing is digital.

Just a little nitpicking.

Hi Steve,



Let me curb a bit your euphoria. Nothing in the real world is digital. All
physical properties are analog and must be transformed into digital data
for further processing. The performance of that hardware determining
resolution, linearity, analogue-digital decoupling etc. is from my point of
view as important as process power and speed.

Your nice call-sign stands for AD (Analog and digital). That is an
obligation, hi.



73, Helmut, DC6NY

After re-reading the past dozen posts, it occurs to me that most are
missing a fundamental point:



DFC/GPU based rigs are nothing more than the next generation of
transceivers.  Just as carburetors have been replaced by fuel injection on
engines, SDR will totally replace discrete transistor/resister/inductor
hardware.  Many of the newer designs from the big 3 are at least partly SDR
under the hood already.

They all soon will be nothing more than computers/fpgas/GPUs inside,
interfaced to nice knobs & displays.



In the tradition of "building your own hardware", we have evolved to just
that: building our own rigs with current technology.  ALL of these
different efforts are useful.  We can all do our own thing, and re-purpose
the good ideas of others as we find useful.
