I guess the key word here is "see". Only in the SDR can you see the spurs, even if you can't hear them.. Most of the spurs I see, are gone by the time they arrive in my passband. Any radio will have some spurs, but they only worry about the ones that can be heard. I'm sure that the SW can be taylored to eliminate all the spurs, but I am not sure that you could afford to run the computer that would be fast or big enough to run it..
