Bill,
There is no such thing as an easy answer on this. But with a bit of
study, you can get a handle on the issue and the magnitude of the fix
needed. I would recommend you track down the W2VJN book "Managing
Interstation Interference." It's got everything you need to get this
under control.

I have a lot of interference on 20m when TXing on 40m even with BPF on each K3
running 100w. A 23' shorted stub at the 40m rig doesn't seem to help. Both
antennas are Butternut verticals about 150' apart. Am I asking too much for the
filters with the same antenna polarization and spacing?
