Since I already have the Ten Tec 221, I'd prefer to see such a filter with a
400 Hz bandwidth. The INRAD 753 is one of my favorite filters, since it seems
to be a good tradeoff between insertion loss and selectivity. Tweak it down a
hundred hertz and it might be the perfect match for the 765.
As I mentioned in my earlier post to the INRAD list, using two 765's-- one in
the roofing filter and one downstream as a 9 MHz IF filter might also work
pretty well.
