Those three in various combinations would work for me!
+ Re "in various combinations", here's an example of what I have in mind:
+ Say you've checked the 80m, FT4, EU, AF, AS, OC, and SA "pre-filtering" boxes:
- all incoming 80m spots would be discarded, regardless of mode or origin
- all FT4 spots would be discarded, regardless of band or origin
- all spots by stations in EU, AF, AS, OC, and SA would be discarded, regardless of band or mode
