Does anyone know about this Sherwood filter: SD-5K/8 IF filter? Is it a
roofing filter ?
Yes, it is a roofing-filter.

What impact does this filter have on the selectivity of an R-4A since the later
filters determine the bandwidth and I prefer a wider skirt for AM reception?
google is your friend, I think the first hit will tell you much of what
you ask.
