I think they're only carrying a syndicated show during morning and afternoon drive, but of course that's when you're most apt to be listening. The afternoon Scott and Sam (Sam being a she) is generally listenable, but the Mornings with Brant show is nothing short of deplorable. It amounts to nothing more than a clone of all the other drivelcasts on FM, with the periodic, obligatory and unconvincing allusion to "we're believers too". It often comes over as more like "hard for you to imagine we're believers too, isn't it?" I don't listen and my kids (13 and 15) won't put it on.
Certainly missed are the years when the morning show was Tim and Heather, or Tim and Heather/Emily, or Dave and Emily. I know WORD-FM has recently been touting the expanded coverage of their network into Maryland and West Virginia, so I suspect maybe the money for "local" went into "expanded network", and voila, syndication.
If you're in Allentown proper, you could try 94.7 for the Family Life Network. It's a translator carrying 91.5 WCIG from Shanendoah. I'm too far away to get 94.7, but surprisingly on good weather days with some fidgeting with the FM antenna, I can get WCIG here in the Palm area of Montgomery county. I spend a fair amount of time along the route 6 corridor in Tioga and Potter counties and discovered FLN up there. They do a great job. Of course, that doesn't give you "local", but I think it will give you what you really miss more than just the "local"
There's also the WBYN option on 107.5 from Boyertown, but if you were more a WORD (WBYO) listner, FLN might be more to your liking
