It is all about the DSP system.  Lyle performed an experimental
test of a 500 Hz DSP filter inside a 2.8 KHz roofing filter, so
the DSP filter was the determinant factor.  Here is his email
again:

The inference I drew from Lyle's response is:
DSP 60 dB BW = DSP Setting + 300 Hz.

You can see that DSP "shape factor" varies with the DSP setting,
so it is easier to remember the DSP+300 formula.
