So long as the band is not totally chockablock with wall-to-wall sigs, I
quite often listen across 2.7kHz width on CW and occasionally I hear people
calling me towards the outer edges.  Mostly, though, the wide bandwidth
allows me to keep an ear on the QRM on either side of me and perhaps to
shift my TX frequency to take advantage of the gaps.  It takes practice to
be comfortable listening in such wide bandwidths, picking individual sigs
out by concentrating on their tone, speed, timing and keying
characteristics, but it saves a lot of fiddling around with the RIT or split
knobs.  That said, when things get real tough or I get tired, I'm very glad
of the ability to shift the upper or lower limits independently, the very
nice narrow roofing filters and amazing non-ringing DSP good down to less
than 50Hz bandwidth.
