That isn't what I was saying. What I was trying to relate was the fact that
your brain is trying to distinguish between a weak signal at a mentally
focused frequency and noise. The way my ears seem to work, the wider the
filter, the wider bands of frequencies my brain can identify as 'noise'. I
am able to better dig out weak sigs with a wide filter than with a narrow one
[assuming the band isn't crowded]. It takes training your brain to do that,
but I've been successful at it.
Where I use tight CW filters on my rigs is during contests where the bands
are *crowded*. If I am trying to work weak signals on a crowded band, it's
tougher [because I have to use narrow filters] for me than on an uncrowded
band given the same noise level.
Anyhow, I'll be getting lots of practice at this the weekend of 6-7 November
in Sweepstakes. Anybody else?
