People aren't listening to a signal, they're listening to contemporary Christian music.
I agree when the second biggest operator of radio stations gets beat by Salem, it is the programming. Y106.7 was a very viable Country station. That was Citadels mistake. Cumulus was / is not smart enough to do something with 106.7. After Lew left they should have done something like put Rock 100.5 programming on 106.7 I guess it would be Rock 106.7? They could have gone toe to toe with 97.1 which would have been interesting. I do like 100.5's station ID which includes "the redhead stepchild of Cumulus."
CBS tried all news in Washington DC, invested millions trying to compete against WTOP, and they lost. Not long after that, management at CBS radio changed, and the company was no longer interested in radio, ultimately selling the division to Entercom. I don't see the same commitment to news at Entercom that may have existed at CBS ten years ago.
They might have picked the wrong city. Why go toe toe with someone who has decades head start. They should have bought channel 46 or used 69 as an O & O built up the local news operation. but that is not going to happen.
