Seriously you wonder why KE5EE, Stan, hears things that you don't hear?
Stan uses stacked arrays on all bands, he even uses yagis for 80 meters so its no wonder you hear him working things that you can't hear.
Also his location in Fla. is near prime saltwater takeoff.
One of Stan's most recent antenna setups is a pair of rotatable hex beams spaced horizontally and fed in phase, so even his hex beam setup is a big step above the average hams.
Stan's a great guy BTW, he recently set up Meralda VP6MW with a brand new hex beam so she could put out a much better signal from Pitcairn Island along with KI6YN who arranged to send her a yaesu FT991A.
Me thinks that Stan's next plan is to try and get Meralda to go the phased hex beam route, now that would make her already massive Pitcairn signal much stronger
You should pay attention to the various dx clusters along with checking out DX maps in particular.
https://www.dxmaps.com/spots/mapg.php?Lan=EWith DX maps you can enable gray line to see what the path looks like between you and various dx stations, and you can also click on a dx station on the map or in the listing and it will open up a second page where you can then predict propagation to the dx station selected.
You already have a good setup for 40 meters and up so I'd guess it's just that your operating times are off and whatever you do, don't try to compare what you have to Stan, KE5EE's setup either.
Be patient at first just to get an idea as to how your your setup performs and don't forget to check out the long path because LP is very useable but you need to get familiar with the times of the day when these far out dx stations come into your area.
