I couldn’t agree more. As Merv says....“It’s hard as heck to get EU to listen on the skew path”.
Last year when the AU was fairly quiet, the direct EU polar path prevailed, but in years past, the skew path was very common. This is also very true for the deep Asia path (HS, 9M2 etc) from VE6 because they are also on a very northerly path. The JAs are not often skewed, usually direct path. All this is also very common on 80m. It is quite normal for the EU signals to be skewed to the south, as Merv says, sometimes with the Yagi pointed to SA. That’s almost a 90 deg path skew! This is NOT subtle, there are time when I have zero copy direct path, but Q5 with the Yagi pointed 90 deg skew. The problem is that many EU ops find that “most of NA” is direct path, but often the west coast and KH6 is coming in over SA, but they don’t move their RX!
Wherever you live in the world, when working the lowbands always check for a skewed southerly path when the direct path is close to the pole.
Having said that, the arrival angle change near sunrise or sunset is also very common, and can be quite dramatic.
