[TenTec] SSB and CW filters wanted

[A R]

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.
