Dear Alan,

if I understand well,you are receiving CW by ear, not by 
Spectrogram.
For receiving CW by ears I found very useful a stereo processor, 
like that described in 

http://hem2.passagen.se/sm0vpo/use/stereo.htm

which allow to "spatially" spread signals (and noise) " in front of 
you":
lower frequency signals are stronger in the left earphone 
speaker, and higher frequency in the right one. In this way you can 
simply concentrate your brain in the signal coming from a certain 
"virtual direction"
It's interesting with large filters (e.g. 500 Hz), however I never 
tryied it with narrower filters. It may need some adjustment...
