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.
