[hpsdr] Hermes II

[Helmut Oeller]

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.

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  Just as carburetors have been replaced by fuel injection on engines, SDR will totally replace discrete transistor/resister/inductor hardware.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.
