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.
