The G303i is the first such software-defined radio for the consumer

True, and the Winradio WR-1000 even earlier, but these are both
conventional architecture (although PC-controlled) radios.

I don't know the WR-100 from inside.
But _all_ alignment of the PCR1000 is done by software.


Proper software-defined radio is such where the entire last IF and
demodulator stage are executed in software (i.e. the signal is sampled
at the last IF frequency).

Do you really mean a DSP as or in the final IF-stage makes the
difference for a software defined radio? All other things is electronic
switchings controlled by software.
