Hi Bill,

This sort of issue is one of many addressed in this talk I've done at Visalia, to NCCC, and a few other local clubs.

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?
