I hear English commercials and Spanish talk?
That is because it is brokered ethnic. According to their website they play Conjunto, Salsa, and Texas Gardening Shows, with a Texas Music twist. Think of it like now defunct-KNAF, KEDA, KTJM Port Arthur, and Pre-Tejano days on KRIO 94.1 all mixed in. It seems like San Antonio's first AM brokered ethnic station. I may be wrong since I hardly listen to AM in San Antonio unless it is KTSA, KTKR, KONO-86, KLUP (sometimes), WOAI, KAHL, or Dx'ing KVNS out of Brownsville.
