[Elecraft] K2 Roofing filter?

[TMorton]

The Feb 05 QST has review of InRad roofing filter for FT-1000MP series. The
article states, "the Ten-Tec Orion and Elecraft K2 are ham band only designs
and thus have their first IF and roofing filters in the HF region".  The
article describes how Icom 7800 has roofing filters at 15 and 6 kHz and that
new Yaesu FT9000 DX will have 2 roofing filters at 15, 6 and 3 kHz.  

The article further states, "Single conversion receivers, such as the K2,
can set both the roofing filter and selectivity with a single filter
following the mixer.

Question, what roofing filter default are we using in the K2 and how do we
change it? Or, is there any need to do so.  I have noticed on ssb that I get
more intermod than during contest ops using cw.
