I'm very skeptical that it's the A/K indices that account for the change in TP propagation over the years.  Now that we have discounted the splatter aspect, according to the experts out there, there's more going on in our 
ionosphere than can be accounted for up to this point.  Looking outside the box, what about global warming, increases in pollutants in the atmosphere, ozone or lack thereof, even the Alaskan HF array pumping megawatts 
skyward.  Unfortunately, I can't comment on my own experiences over the years, since until the last several years, I was a dedicated SW dxer only.......Walt
