I'll only comment on question 3.  I still want to buy a 480, but must clear
some stuff out of the basement before Judy will consent.

I wonder how effective a 1.8 KHz SSB filter would be.  I got a 1.5 for my
Drake R4C, and that's too narrow to be useful.  The crystal filters will
probably have a more gental slope than the audio DSP filters, and provide
protection against the AGC being pumped by signals that the audio DSP is
rejecting.

For CW I would get a 500 for sure.  For me, I would probably get a 270 also,
because it's likely to be useful when you're trying to hear DX on the low
bands.  For most purposes on CW, a 500 or 400 Hz filter is optimal.
