a. So publicly advocating against the use of fan dipoles is not a
"crusade" of sorts?
b. You think bad key clicks and SSB splatter 3 db down aren't at least
as easy to detect as a harmonic 30 db down?
c. You think key clicks and SSB splatter aren't a far more pervasive
problem than interference from harmonics?
We must be living in different realities with some sort of planar
junction at this reflector.
