Maybe none. You get great filtering out of the DSP. The roofing filters
are most helpful when very strong signals are present nearby. Operating
mostly
QRP, you might never run into that problem.

I would echo the other responses that you may well not need any
narrower roofing filters. You might try using just the stock 2.7 kHz
filter for a while and see how it goes. I recently added the 400 Hz
filter and so far, it makes virtually no difference EXCEPT in the case
where there's a
I have a K3/10 which I use for CW. I got the 13 KHz (for AM bcst) and
500 Hz filters, which I'm happy with. I could get a narrower one but
just haven't felt the need for it yet.

Mike,
If you do any contesting or if you want to operate during a contest, roofing
filters are the way to go. As I get older the pumping noise from adjacent
signals has become ever more distracting. The rig I used for the California
QSO party was new and had a Collins 500Hz virtual roofing

the contest some stations could copy me but I could not copy them due to
the
pumping generated by adjacent signals.
