[Elecraft] K2 -- is this normal?

[Eddy via Elecraft]

Greeting all to all the K2 wizards out there! I'm more curious than concerned, using CW, I notice when I go from FL1 to FL2 my general "noise level" seems to go up to the point I need to turn down the volume -- is this normal behavior? I would expect the noise level to go down as the filtering gets narrower? 

I looked at the filter bandwidths using Spectogram and they look normal to me. I set them per Elecraft recommendations. My K2 serial # 3500+ with all the firmware updates and the K2DSP installed.
Happy Holidays to Elecraft and ops.
