On a bussiness trip about 12-15 years ago, one mid-afternoon, I checked into a Holiday Inn Express in Carpenteria....a coastal community basically adjacent to Santa Barbara. As is usually the case in hotels, the room had a dirt-cheap tiny clock radio, Normally I don't even bother to turn one of these on, but for some reason on this day I did. To my surprise, XEPRS was one of the strongest signals on the dial. As strong, if not stronger, than any of the big L.A. signals on this little radio with lousy sensitivity.
In the 1971 TV documentary entitled An American Family, the teenage son of the family is shown driving very early one morning in Santa Barbara, where they live (either he's coming home very late from a night of partying or going somewhere very early). He is listening to the radio, and the ID is heard -- it's 1090 AM and sounds like it's booming in.
