yeah, I pushed send too soon... I only have experience with audio DSP, so I guess I remain dubious until I learn more. My gut feel is that I want the first filter at 1.8 and then go DSP from there.

Since the designers are offering a 200Hz filter I infer they feel the same way about CW. But we'll see soon enough.

If Elecraft does not list a 1.8 kHz option in their selection of roofing filters there's a possibility that INRAD will. But please remember you are talking apples and oranges when comparing the filtering between the 1000D and a K3. That 2.1 kHz option IS a roofing filter and then you can narrow the final bandwidth using the
DSP HI/LO- cut controls as narrow as you need to.
