We're talking roofing filters here, not operating bandwidth.  The 
functional difference between a 750 Hz roofing filter and a DSP setting 
of 750Hz versus a 1000 Hz roofing filter and a DSP setting of 750Hz is 
just plain trivial ... ESPECIALLY in a non-contest environment.  At 
least it seems Inrad understands that.
