Idiom Press sells a filter called the SCAF-1 which acts as a bandpass
filter with a variable high end. With one you could narrow things down
for a CW signal quite well.
More information and demo .wav files are available at:

And #2, how well do audio filters, or even audio DSP like SGC sells, for
narrowing things down for listening to CW?
