[TowerTalk] Beverage Intermod

[Robert Pack (NX5M)]

A recently installed 40m stack is 100 feet away from my main (best) EU beverage.  Since this install, the qrm on the beverage is bad enough that I cannot listen on 160.
I have also had issues with being able to hear when someone is transmitting on 80 as one of the 80m antennas is about the same distance away as the 40m stack.
I built bandpass filters for the 80 and 160 rx systems but this just does not seem to be enough.
All other beverages are relatively unaffected.
Other than tearing down the beverage and relocating it 600 feet away, which means clearing quite a bit of thick underbrush, any of you have any ideas how to clean this mess up?
