VERY interesting. I have found myself using wider bandwidths since
getting the DSP, and now I understand why. Before installing the DSP, I
was often reducing the bandwidth to improve the s/n ratio and only
rarely to eliminate QRM. I guess that for the kind of noise I seem to
be dealing with, the DSP approach is more effective. I think I will
rethink my crystal filter b/w settings in the light of this.
