Hey, thank you, Robert !! That excellently addresses my question !
So I see that for -60 db the response seems to be +/- 8 kHz.
Actually, not that great, for the low IF, which if I recall is, well, I can't recall, but think maybe 112 kHz.
I just took a look at Pat Hawker's book and wouldn't you know it, both the RBM and the RAX (LF)  IF's are not listed.
The HRO-60 I have, has 5 kHz selectivity at -60 db, BUT …… 2 RF stages at AM broadcast band is insane design.

Does one of the RBM manuals spec the selectivity of the MF receiver?

I am trying to decide whether to keep the MF receiver for AM-band DXing.
