The emphasis of my questions are based on European propagation path perceived differences since last solar minimum.
I suspect much of the difference may be RX noise levels at both ends of the path. The number of RX noise sources has mushroomed over the past decade, with SMPS, variable speed motor controllers, solar systems, and the bean counters at power utilities that down-prioritize the maintenance of their distribution lines.
