I wonder what programming they're using. I've observed that other than Erazno y la Chokolata, their programming seems to have high turnover.La Playa has flipped to Radio Tricolor, per Radio Insight. New format is Regional Mexican, which makes much more sense.
The Tricolor morning show seems to be mostly an afterthought, and they really prefer to put their resources in El Genio Lucas from the Suavecita stations.
