104.3 was doing for the most part the same thing Audacy (er CBS Radio at the time) was doing with their stations in New York and Los Angeles until Entercom took over in 2017 and backed out of it.

94.7 benefitted the most. They also shifted into a more uptempo presentation after. They otherwise didn't really change much.

And if you don't think MeTV-FM is a factor, think again. It's not the "Oldies" station it once was. They play tons of 70s and 80s now, with some 60s. They just played Together Forever by Rick Astley which is from 1988. The upper end of the demo is likely listening to 87.7 instead of 94.7 or switching between the two, and potentially WLIT. 94.7 is not a standalone like WCBS and KRTH.
