Yes, but the 2.4 and 1 khz roofing filters take care of cleaning up the
area. You don't need to go to 1.8 or 250 with the roofing filters.

Carl,
Is that really true? Aren't the 218 and 219 employed as roofing filters
in the 1st IF, and isn't the DSP BW control in the 3rd IF? If strong
adjacent (and/or dirty) signal conditions warrant tighter/narrower BW
roofing filters than the narrowest 2.4KHz and 1.0KHz roofing filters
supplied as "standard" in the ORION, then wouldn't the option roofing
filters at the 1st IF be more effective in dealing with the consequences
of strong adjacent/dirty signal conditions than at the 3rd IF?

You don't need them. The skirts on the Orion DSP filters are very sharp
making those filters not really needed.
