You're wasting your time.
You already found the forest. If you ignore the trees, you'll see it! (hi)
That filter probably has a bad crystal.
Just get a new filter Stan.

??? The 2.4 Khz filter I have is broken? That's what I think. I
wouldn't think -24 db for the peaks in the passband of the filter would be
"normal" The other filters were all around -15 db peaks in the passband. I
would post the frequency response graphs, but attachments are allowed on
this group.
