Friends in Radio Land -
I agree with Bill Tippett that auroral reflections play an
important role in 160 meter propagation, his QSO with SM6CPY being a
prime example. But I disagree with him about the importance of
scattering, particularly with regard to the SSE/SSW paths he
pointed to. There, in my view, scattering plays a major role,
making short-path signals look like signals from a "long-path"
direction.
I think it is time to put both views on the table and looking
hard at the problem, not just repeating the same words and
phrases over and over again. Having given my views in a
technical article in QEX, I would be most interested in reading
an article on 160 meter propagation which justifies SSE and SSW
propagation based on the physical principles of propagation. I
would hope the author signs his/her name to the paper and has it
published in a reputable journal for all of us to read and
evaluate. That's the way we do things in the world of science
and when I last looked, the propagation was still a physics
problem, based on the principles of Maxwell and Appleton.
