Spur Reduction: Adds the use of a software oscillator to avoid
DDS frequencies known to have a higher phase truncation related
spurious response. In short, rather than tuning each frequency
using the DDS (this is what happens when this option is turned
off), the software tunes the DDS in 3kHz steps and does
fine-tuning in software. Tuning in 3kHz steps also has the
advantage of having to send fewer command signals to the hardware.
-From the manual, page 84
CW Skimmer is not intelligent enough to dodge the spurs and
won't follow the Flex-3000's algorithm.

I know the "SR" button stands for Spur Reduction, but I'm not certain what
that means in practical terms.
Is a spur like an image signal?
What got me thinking about this is the fact that CW Skimmer wants this to be
turned off. I can see that Skimmer sees things differently with it on or
off, but I don't know why that is.
Also - is this something that has to do with receive only?
What's really on my mind is - when I stop using Skimmer is it very important
that I turn SR back on?
