Analog filters have phase delay. That would be stronger with a narrower filter.
Also, the on-off CW signal has sidebands (the harmonics of the square wave).
Maybe a narrower filter sounds “softer”? I have no idea what “full

This is the degeneration of Amateur radio, yes really, it's true. These
signals from Eu are invariably the dirtiest worst you will ever hear on the
bands, spewing crap all over the band.

For one thing, you would hear more clicks with the broader filter. You
would, of course, also hear MORE signals.

Interesting!
Can anyone explain why zero beat CW would sound more "full bodied" with a
2.7 KHz IF than with, say, a 400 Hz IF bandwidth? It would seem that the
CW signal was typically narrower than either one, so there would not be any
information lost on a zero beat signal.
Is there some sort
The killer for that wide roofer approach is that loud enough stations can
pump the hardware AGC before the signal gets to the DSP.

Hello All,
I did M/M with a big station in the NW running Icom 7700. Needless to say
comparison between K3 (one was on site) versus Icom radios came into discussion
during rest periods. Yes, the Icom 7700 played quite well, giving what some
called "full-body" cw and easy to pick-out-stations
