I don't know what radio station in San Diego you are talking about, you didn't even give us call letters or frequency.
98.1 is doing a softer version of classic hits.
96.5 is a normal adult contemporary station like KOST.
Neither of these fit the definition of soft ac, but in 2023 what is soft ac?
Looks like there is Adult Contemporary and every station of this format adjusts their currents, recurrents, and gold songs percentage of playlist based upon their own specific market conditions, that's market demographics, the competition, and their own cluster strategy.
Then the subjective how soft or loud are they. But then many of these stations daypart.
As mentioned, you don't put on a station that w ok would completely cannibalize your own, so I guess you want to blow up the Wave too? So Kroq becomes K-Lit, and KTWV? You wanna maybe change them to Rock. Lol
Maybe 94.7 could become the latest and greatest American clueless version of EDM where it's specially programmed to do such a niche format as awfully as possible where as if it was done would need to be executed flawlessly. Yeah that happened on 103.5 in New York in 1996, and within 5 years they changed it.
