The 3.27 NR F3-1 is *identical* to 3.25 NR F1-4.
The 3.27 NR F3-2 is *identical* to 3.25 NR F2-4.
The 3.27 NR F3-3 is *identical* to 3.25 NR F3-4.
The 3.27 NR F3-4 is *identical* to 3.25 NR F4-4.

The 3.27 NR F1- is "lighter" than the 3.25 NR.
The 3.27 NR F2- is a little lighter than the 3.25 NR.
The 3.27 NR F4- is "heavier" than the 3.25 NR.

I am an SSB op, not a CW op, and the NR now works much better for me.

There were some changes we had to make from 3.25 (and previous releases 
as well) in the Fx-1, -2 and -3 settings which resulted in "scolloping" 
of the passband.  Some CW ops at certain pitches thought it gave their 
signals a boost, others at other pitches really bemoaned the 
attenuation.  While less noticeable on SSB, it was there nonetheless.
