Topband: Correlation

[Roger Parsons]

But it does mean there won't be a path to anywhere
when you are slap bang in the middle of the
absorption!

I do believe there are often enhanced conditions for
stations at the right distance south of the auroral
zone, often over quite a small geographic area, during
periods of high geomagnetic activity. It doesn't take
a huge leap of faith to imagine that those enhanced
conditions can provide viable skew paths. But I am
quite convinced that those paths do not include
stations effectively covered by the auroral oval at
any particular time.
