Sadly if the splatter is real (not an artifact generated in the receiver)
and the splatter is in the passband, no amount of filtering is going to help
get rid of it. If the other guy's signal is broad then there isn't much
that can be done to get rid of it given today's technology.

Subject: [Elecraft] filters and contests and interference question/opinions
After spending time in two DX contasts this year and also dealing with lots
of splatter from other stations during non contest conditions I find myself
continually dialing down tighter and tighter filter settings on phone (ssb)
Currently I have a 2.7, and 2.1 filter plus the narrow ones for digital.
My brain is starting to tell me to stop using the 2.1 and get either a
1.8 or even a 1.5 or possibly both. My thoughts are that the dsp would
work much better if some of the interference can be directly blocked out
by the filter. These thoughts are guided by past readings on the list
that this is the case.
What is the collective wisdom of these filter changes I am thinking
about. I am curious about others who may have tried these and if they
kept them or if they thought it made no difference at all.
Again thanks in advance for your help.
