Hi Dennis it isnt called that by the professionals. Radio Luxembourg was one
of the strongest pre WWII BC stations in Europe and it gave problems in the
UK with stations further into Europe.

Try searching for Ionospheric Cross-Modulation or maybe ionosphereic
intermodulation. I had long discussions with Vaino OH2LX about this many
years ago before he became ill. One of the best researches was done by an
engineer at the BBC but I dont recall his name. I maybe still have the
references.  From what I remember the effect is roughly along a line with
the "victim" furthest from the receiver but very approximately the other
side of the "heater" (as one might expect)
