Hello Bob,

Could you resume in a few sentences the difference between the
SoftRock-40 and the SDR-1000 in this regard?
I could go back to the articles on the SDR-1000 and try to figure it
out, but I think that you can give a better answer.

The softRock-40 has a fixed oscillator and can software-tune +/- 24
kHz around that frequency which means that near the oscillator
frequency we get "junk". With the SDR-1000 what happens when we tune
a particular frequency?
