Sorry, but I'm not going to feel bad about being able to slot into a narrower
window than someone else. Where would you draw the line? Lots of folks don't
even have a narrow filter, and lots of folks have rigs that de-sense from
strong signals 10-15 KHz away so badly that they have to stay even further away
from any of the big guns. Besides, there are LOTS of disparities in a contest
that affect where you can successfully operate ... raw signal strength being
one of them. Nobody cut me any slack (nor would I expect them to) during all
the years I was limited to wire antennas and verticals.
The K3 isn't the only rig that can do that anyway ... the Orion II has been on
the market even longer. I think the Flex SDR gear can do it also, and
apparently the new FT5K.
In any case, the solution to QRM during a contest isn't to trash up the ether
by intentionally making more QRM (i.e., a wider signal).

You might be right on that. Some others have mentioned the fact that you
can 'get within 200 cycles' of another station and just keep on operating.
What it that other station has a 400 or 500 cycle filter in HIS radio. Is
he supposed to just move and find another spot to operate? May be quit
contesting because his radio is now inadequate?
I noticed today during the NAQP on 20, I had been on 14.119 for over an
hour and all of a sudden someone showed up almost right on top of me and
started CQ'ing. He was loud, so I know he would have been able to hear me
alright. I was kind of wishing at the time I could have made my signal a
lot wider!! 73
