I think it depends on how much of the "r" in "sdr" is "sd". The k3 does all
the baseband modulation/demodulation in DSP, but has a pretty conventional IF
path. Some people consider the K3 an SDR because it doesn't have a conventional
analog modulation/demodulation stage and uses the DSP for more than just simple
filtering functions in the audio stages.
Personally, for me, it's not an SDR unless it just digitizes everything that it
down converts and has final selectivity in the IF implemented entirely in DSP
(ie no crystal filters and the like) Basically, there needs to be an ADC
running in the mega sample per second range digitizing a wide swath of spectrum
for me to consider something an SDR, but others seem to be more lenient with
their definitions ;-)
