[Elecraft] Filter width and cutting off CW

I'm just finally getting into hunting for CW on the bands to listen  
to, to help improve my on-air listening - I can read about 7WPM (20  
char speed) and trying to find signals with my K3.
I can hear a few around on 40m with the filter set to 1.8KHz, but when  
I start to reduce the filter width down, I loose it at 500Hz - I can  
hear very well at 550Hz, but drop the 50Hz and it disappears - this is  
after doing an auto spot.

Tuning around the frequency, I still can't find it.
Is this a combination of filter width and my sidetone pitch, which is  
set to 500Hz?

I have latest beta f/w, a 400Hz, 1.8KHz, 2.8KHz and 6kHz filters
