[TenTec] WIDER FILTER FOR WEAK CW DXING?

["Jeff Frank" <jafrank@nyc.rr.com>]

I have an Omni 6 opt 1, which I like very much, but on weak cw signals, my 
experience with the filters seems counter-intuitive. I almost always have 
easier and clearer copy on weak cw signals when I use the 1.8 khz filter vs. 
the .5 or .25 khz filters in my 6.3 mhz IF. I've got nothing in the N1 
position. Is this the way it's suppposed to be? I always thought narrowing the 
filter bandwidth is supposed to cut down on noise but it seems opposite. Has it 
got something to do with receivers that are optimized for adjacent signal 
rejection vs. signal to noise ratio? I think I read that somewhere. Can anyone 
explain this to me? Thanks.
