bandwidth must not cause splatter or keyclick interference to operations

To digress to SSB for a moment, (a) means IMHO that the *necessary*
bandwidth should not be greater than 2.2 kHz for voice. Very good 'smooth
sounding' and effective voice SSB can be produced using a filter of this
bandwidth.
Sorry for the digression.
