Last year, rock station KSJO 92.3 disappeared and was replaced with "La Preciosa". This year, KCNL 1049 (Channel 1049) also vanished and is now "La Romantica". Apparently this is just a move by Clear Channel to sell advertising: Radio 101 KCNL Drops Alternative - The Anatomy of a Format Change
As all the 92.3 folks moved to 107.7, I expect the 104.9 folks will move to 105.3. Whatever happened to the free market?
