I was never a fervent FM or TV DXer, so I'm poorly versed in such things as ESkip and Trope, or the distinctions and extremes within. All I've known is that DX is DX, irrespective of waveband, and the reception of anything unusual is riveting.
Around 1971, my Dad Al* bought a new TV console that contained UHF capability. And one afternoon near JFK Airport, with only a mere and traditional attic TV antenna pointed at the Empire State Building, I tuned around the UHF dial and got a decent-enough signal from the aforementioned WBOC, channel 16, from MD.
Dad never understood my enthusiasm for DX of any sort. I'm supposing now that the WBOC-16 reception was 'trope'.
That generation gap is understandable. Dad was a lab technician at Mobil for 35 years and could tell you what *state* the car whose muffler residue he was analyzing had driven through recently. But he could not comprehend why, at the Folks' retirement home in Florida, there were two Channel 9's on his cable remote -- WGN Chicago for the Cubs and WWOR New York with his Mets games. The twain never met between us two as far as distance and states and subsequent intrigue and curiosity went.
