I guess that 10K signal would give them a strong signal throughout Delaware to the beach maybe to Ocean City, MD and with a stronger back and side signal a stronger signal in Philly as well as in Cecil and Hartford counties in Maryland. That can only be good for WDEL. AM radio may be dying, but it appears that WDEL isn't going down without a fight.
Of course that then makes one wonder how long before WILM and WWTX apply for a power boost to say 2.5kw or even 5kw daytime from their meger 1kw setup's now.
