Just to prove that its no artifact of freedv, the same effect can be seen in fldigi.

Strange filter artifact in KX3
I've just discovered a strange filter artifact in my KX3's filtering. Whilst fiddling with freedv, and adjusting the PBT high cut frequency with the rig in LSB mode (not DATA-A), as I adjust the PBT-II function downwards, a notch appears at 1500Hz, as soon as FL2 activates. I have the optional roofing filters fitted, as shipped from Waters and Stanton, and have performed no calibrations myself, yet.

Has anyone noticed this?
Update: Yes they have. It is explained here.
