KJXK (102.7 FM, "102.7 Jack FM") is a radio station in San Antonio, Texas, broadcasting an adult hits music format as a member of the "Jack FM" brand. Its studios are located in Northeast San Antonio, and the transmitter site is atop Tower of the Americas downtown.
102.7 signed on in 1969 as KTFM. In 1972, KTFM was looking into a format switch to progressive rock, making that change late 1972-1973. This format lasted until at least 1976. In the summer of 1986, the station changed its format to a mainstream pop station that would later evolve into Rhythmic Top 40 by 1988. The station at this time was owned by Waterman Broadcasting of Texas. KTFM was the Dominant Top-40 station competing with then KSAQ Q96, which would become KXXM Mix 96, and now defunct KITY "Power 93" (92.9 FM) now Regional Mexican "Estereo Latino".
In 2000, the Top-40 market would be shook up by the arrival of a Move-in at the 98.5 Frequency. KBBT was launched as "The Beat", a new Hip-Hop heavy Rhythmic format which quickly climbed up in the ratings. In August 2001, KTFM would go after KBBT by changing from Mainstream Top-40 to a more Rhythmic Based Top-40 as "Wild 102-7". KBBT had the Hip Hop music audience, and KTFM started to see their ratings slide down.
Infinity also owned Sister then Top-40 KRBV "Wild 100" (now KJKK in Dallas) with the same format looking to bring down KBBT 98.5 "The Beat. Infinity would finally throw in the towel and drop "Wild 102-7". KTFM reverted to mainstream Top-40 with some Rock cuts mixed in. By October 2003 KTFM 102.7 "San Antonio's Original Hit Music Station" called it quits as a CHR and flipped to rock/classic rock hybrid format known as K-ROCK; the call letters would become KSRX. On 1/1/2006 after a "Free FM" stunt, like the other stations that were to flip to Jack across the country, KSRX was dropped in favor of the popular "Jack" style format. 102.7 became "102.7 Jack FM" with the KJXK calls.
In August 2006, CBS Radio sold KJXK and KTSA to Houston's Border Media for $45 Million dollars. BMP Media would Revive the KTFM calls in 2005 on 94.1 FM, which has since reverted to its Legendary Top-40 format. Jack FM is San Antonio's home for the Dallas Cowboys.
On January 7th, 2016 at 4PM, after a half hour of "goodbye"-themed songs (ending with "Someone like You" by Adele), 102.7 briefly stunted with country music, keeping the Jack-FM name, but including barnyard sounds in their bumpers and branding their Facebook page as "102.7 Yeehaw FM". As 94.1 was stunting at the same time, this led listeners to believe KTFM was moving back to 102.7; however, at 5PM, Jack returned, and the country music was revealed to be a publicity stunt.
