It looks to me like you still have to set the offsets. See manual. It
doesn't appear there is any difference between the K3 and K3s as far as
filter offsets.
When I set up my K3, I tried to get the 200 Hz filter offset "just
right", so the noise would sound exactly the same in USB or LSB (CW or
CW REV). I found that the filter drifted around quite a bit with
temperature. So, if you have the narrow filters, let the temperature
stabilize before setting the offset. Wider filters are much less critical.

Eight pole filters have a metal can enclosing them. The five pole filters are
just exposed PC boards.
I think I have offsets set on my K3S for the 200 Hz filters.

I just received my 500hz filters from Elecraft. I guess I assumed they were 8
pole, however they are 5 pole. The web page does not specify 5 or 8 pole, or I
did not navigate the webpage properly.
So now that I have 5 pole filters, I seem to recall that entering the offset
freq is not required any longer on the K3S, is that true?
Also does a K3 upgraded with K3S features need the offset freq?
I should mention that they are all matched.
Is there a graphic representation of these 5 pole filters available?
Thanks
