[TenTec] Noise reduction of roofing filter?

[Peter Hoon]

Fellows,

Am hearing disabled, own an Omni 6 Plus mostly for CW, and cascade the 250
Hz 6.3 IF CW  filter along with the "low note" 221 250 Hz CW filter in the 9
mHz IF (position N-2).

In reality, my stock 2.4 kHz filter is always in line along with both the
250 Hz CW filter.

If I were to add the Inrad 765 500 Hz roofing filter offset for the special
221 filter, would I experience less atmospheric noise at the speaker?

(I realize that the roofing filter is normally used to improve third order
IMD, but am intersted in knowing if I would also gain an improvement during
the summer when the 40 M band typically has high back ground noise).

My NR in the Omni 6 plus works well, but there are occasions where the band
is so noisy at my location, I am considering possible QRN noise reduction
advantages from a roofing filter.

Thanks for any and all suggestions.
