I think Broadcast Guy answered your question: "There are actually two more Latin stations in that area, WKDB 95.3 Latin Hits "Maxima" in Laurel DE and WJWL 900 AM and translator 100.3 FM Regional Mexican "La Raza" Georgetown DE."
Three Hispanic stations LSD [Lower Slower Delaware] and apparently WYUS was on the bottom of the pile ratings and possibly spot revenue wise. Or at least not doing well enough for Delmarva's management thus the change.
Was WYUS doing any live and local programming? If so, those employees cost money, ESPN Radio from the bird only needs an FM jock, from one of Delmarva's FM LSD stations all located in the same building, to occasionally go to the "AM station in a closet" and reboot the computer if it goes out to lunch. 1290 WWTX [Fox Sports Radio] and WILM [Premiere Radio during the day] have this happen to them sometimes during daytime parts. WDEL has had it happen at night when it too is on the bird.
Usually when the AM computer goes off line, a blinking light blinks in the FM studio across the hall [WSTW for WDEL] alerting the FM jock to go reboot AM station's computer. My experience is, they must not give it a high priority as WILM and WWTX can be broadcasting a beep beep beep sound from the satellite for 1/2 hour or more before the FM jock decides to go fix the problem. Try calling a station to let them know. It's not like the old days when you could call the lone person in the radio station and they'd answer the phone. AM just isn't the priority any longer for Clear Channel Delaware or Delmarva Broadcasting. FM is where they make their money and thus the effort.
WDEL daytime is live and local, with a pretty hefty staff of news folks, so for now Delmarva is able to make WDEL be financially viable during the dayparts [weekdays], but eventually that too will change, note their promote the heck out of their WDEL-FM 101.7 signal and barely mention 1150 AM. Got to go where the demo's the advertisers go to listen to the radio and it's not AM, but FM.
