These are some great things to think about.

Perhaps I may have been hasting into concluding we needed the filters in
the first place when some more easily implemented practices should be
tried first.

I think the best thing will be to only use the "good" radios on the same
bands and better utilize spacing and polarization to see what best we can
achieve. One of the other ideas I think we will be considering will be to
limit power for CW and digital modes as well. I am also having high hopes
of separation as I think there may have been some coupling induced by the
common ground and shared power supplies. Perhaps having two compounds
with separate infrastructures and space would reduce problems to a more
tolerable level.

Thank you all for you response!

Don't neglect common mode feedline current as a potential source of
unwanted coupling. All your efforts to control polarization and
physically separate antennas can be largely wasted if your feedlines are
radiating.
