I am confused about "1831.5 being occupied."  Is your situation:

1.  The NB works well on the noise, but gets falsed by nearby
signals on a crowded band in the contest.  IOW, the NB
would have worked fine during non-contest times.  The NB
on my FT-1000 is like this (I have the W8JI NB mod).

or

2.  The local noise was lower on 1831.5, but you still needed
the NB.  QRM from other stations was not an issue.

I don't own a K3, but an considering buying one.
