Some things we need to consider and remember when discussing WRDX (Tom-FM) and WDSD. They are Dover stations. Dover isn't a rated market. We see WDSD and WRDX show in both Wilmington and Salisbury markets, but really have no idea how well they do in their primary market, Kent County. Both may be the major listen to stations in Dover/Smyrna/Milford. CC Delaware surely knows the answer to that question, which may be why they keep those stations as they are.
As Wilmington rimshot stations the 12+ numbers aren't great for WDSD as WXCY is the major player for Country music in New Castle County also beating out Philly's WXTU which has even smaller numbers than WDSD (of course WXTU doesn't really care if they're top dog in Wilmington, Philly's their target). WDSD lost that top dog spot for country music years ago when their format was switched with WRDX making the weaker 92.9 country. WDSD hasn't been able to win back those lost NCC country listeners from WXCY after switching back to country a few years ago. I listen to WDSD because it comes in far better at work. In my car, I'll see which has the music I want to hear or which is in a long spot break, as I can get both well there. They both essentially play the same music. WRDX does even worse in Wilmington.
However, the big question is, what is their billing? Just as with WWTX AM1290, Wilmington's sports talker that rarely shows at all on the 12+ numbers, but none of us know how well these three stations bill. WDSD airs a fair amount of local spots, so someone is buying local time on WDSD, and they're not all Dover advertisers, many are from the Wilmington area. My point is, WDSD and WRDX may be making reasonable money for CC Delaware just as they are, which is the bottom line. WWTX doesn't sell many local ads, but apparently, just as with news/talk WILM and WDOV, CC Delaware must make money by airing the Premiere Radio Network shows clearing two additional markets, essentially the entire state of Delaware (other than the beach) for the Conservative Talk CC's network provides and the Wilmington market for their sports talk programming.
I said a lot (not very well) to try to say, granted, each one of us probably had our own ideas as to what would make each of those stations great, but as radio isn't a hobby for CC Delaware, they need to make money and that's the one piece of the pie, we here don't have data for. WWTX, WDSD, WRDX, WILM, and WDOV all may be making reasonable money for CC Delaware (especially in this economy), even though as a listener and radio geek, we don't see how. Now granted, if CC Delaware's stations are NOT making a reasonable profit, then we might indeed see some changes.
I'd agree with Don C, that all four of Delaware's news/talkers WDEL, WILM, WDOV, and WGMD-FM Rehoboth Beach are very good stations that are serving their respective markets quite well. As Delaware truly lacks any real TV news coverage for Northern Delaware, other than the once a week news magazine "First" on Channel 12 Wilmington / 64 Seaford (which is well done and worth checking out) radio offers the only other Delaware news source other than the Wilmington News Journal. Lower Delaware does get good local news coverage from Salisbury's TV stations and Dover's Del State News.
