I've had the occasional good fortune to catch over the air digital TV broadcasts that were being propagated over a long distance, usually from northern Missouri.
Probably the "best" DXing experience I've ever had, though, was in late 2014. I was cruising down the road, scrolling through the FM dial when suddenly KLOU came in loud and clear! I'm only about 300 miles away in Illinois, so this was quite a surprise and definitely like nothing I'd seen before.
Reception was clear as a bell, and even the RDS data was coming in perfectly.
Luckily I met up with my father and asked to borrow his phone to get some
video. The reception window stayed open for hours. I later tried some stereo receivers and (very good) standalone tuners hooked up to an outdoor antenna, but none of them managed the outstanding performance of the radio in my truck.
