[Elecraft] [K3] SSB BW 6Khz with FL1=2.8Khz

[Leigh L. Klotz, Jr.]

I finished K3#51 (as far as QRP) a couple of hours ago, and have a 
filter question.

I have FL1 setup as 2.8Khz and confirmed it in FL1 BW as 2.80.
When I am in USB or LSB mode, I can adjust the width past 2.8 up to 6.0.
The bar graph display maxes out at 3.60.  There does seem to be an 
effect on the audio.

I assume this means that the DSP filter is adjusted to pass the skirts 
of the 2.8Khz filter instead of cleaning them up.
Is there a section in the manual I should read about these widths 
large-than-life widths, or any experience with them?
