Thanks Darrell,
I guess if I wanted to tighten it up, I could add some sort of a
q-multiplier circuit for cw.

I believe they would be just about right for communications type AM. I
recently converted a HBR-11 for AM use using a 2762 Kc first IF and 262 Kc
second IF. It was too wide for use in anything but a sparsely occupied band.
