The West Valley Amateur Radio Association (WVARA) Field Day
operation, using the K6EI call, has been using a mixture of
mostly K3s with some K2s and KX3s. We run QRP and last year
entered as 11AB. We have very little difficulty with mutual
interference, even when we are running SSB, digital, and CW on
the same band.
The only extra filters we use are in conjunction with a
triplexer which lets use one tribander on 10M, 15m, and 20M at
the same time.
We have been quite successful with the approach for many years
as can be seen from the field day results.
This year, we took our operation to Sierra County for the
California QSO Party. There we ran 2 K3s and a KX3, all at 100
watts. We kept the SSB stations on separate bands. The worst
interference problem we had was when our batteries got low and
we got a lot of IMD in our signals. That caused interference
between our stations. Replacing the batteries with freshly
charged batteries cured the problem.

I am using Field Day as a worst case scenario. I can't think of
any situation that is worse than have a collection of radios
operating in close proximity, to include their antennas. QRP
operation does offer the least challenges, but it still does
have its problems. At the other end, the serious QRO stations
like W3LPL all take special precautions in field layout and
they use bandpass filters. However, I think you know all that.
