KZAR began operations in July 1989 as KQRO-FM, a 3 kilowatt class A facility licensed to
Cuero, Texas, changing call letters to KVCQ in 1995, KNGT in 2003, and KLTO-FM in 2005. It moved to its current tower, licensed to McQueeney, Texas, and upgraded to the current C1 class by 2008. When it moved to San Antonio, KLTO-FM broadcast a
reggaeton format until 2008, then changed to
rock under the "977 Rock" branding. On February 4, 2011, the station changed formats to
top 40 as "Party 97.7". The station's direction leaned towards
dance, but played the usual top 40/CHR fare, similar to rivals
KXXM and
KTFM. On August 15, 2011,
Univision Radio sold KLTO-FM to
Educational Media Foundation, which flipped the station to the Air 1 network (which at that time carried a
Christian rock format) in mid to late November. Its previous formats could be heard on
KBBT HD2 when Univision had it. ==See also==
