KTKX (106.7 FM, branded as "106.7 The Eagle") is a commercial broadcasting station licensed in Terrell Hills, Texas, catering to listeners within the San Antonio metropolitan area. Owned by Cox Media Group, KTKX operates alongside sister stations such as KISS-FM and KONO-FM. The station airs a classic rock format, complementing KISS-FM’s active rock and KONO-FM’s classic hits by incorporating crossover classic rock selections.
The studios for KTKX are situated on Datapoint Drive in Northwest San Antonio, close to the South Texas Medical Center. Its transmitter, which broadcasts with an effective radiated power of 100,000 watts in HD Radio format, is located off Hallmark Path in the southern part of Bexar County.
106.3 KTUF and KESI
Prior to 1979, the 106.3 frequency in the San Antonio market was occupied by KBUC-FM (currently known as KVBH). That year, KBUC-FM relocated to 107.5 FM, making way for a new station at 106.3. On July 18, 1979, KTUF launched as San Antonio’s first commercial FM jazz station. It was owned by Southern Sound System Broadcasting Company alongside KAPE (now KCHL). Operating as a Class A station, KTUF transmitted at a modest 3,000 watts.
In 1982, ownership changed hands to S.I.T. Broadcasting. The following year, the station shifted its format to album rock and adopted the call sign KESI. Subsequently, it cycled through easy listening and adult contemporary formats under the moniker "Star 106." However, its limited power hindered significant ratings growth during these transitions.
Relocation to 106.7
In 1986, KESI transitioned from 106.3 to 106.7 FM, significantly increasing its output power to 100,000 watts. The next year brought a rebranding to KMMX "K-Mix 106.7," featuring an adult contemporary format that persisted for several years.
By November 1992, KMMX entered into a simulcast arrangement with country station KKYX, changing its call letters to KKYX-FM. This strategy resulted in three full-powered FM country outlets in San Antonio: KAJA and KCYY focused on modern country music, while KKYX-AM-FM catered to classic country enthusiasts.
The simulcast concluded in 1993 prior to the San Antonio Stock Show & Rodeo event. Subsequently, KKYX-FM adopted a Contemporary Country format branded as "106.7 The Armadillo," changing its call sign to KDIL—a nod to the local armadillo species.
Smooth Jazz Era
After two years under New City Communications—owners of KCYY—106.7 was rebranded as "Smooth Jazz 106.7 KCJZ" on February 24, 1995. This change was designed to prevent format overlap with KCYY amid fierce competition within the market.
Rhythmic Oldies Period
In 1997, Cox Communications acquired KCJZ along with other New City stations. On July 1, 1999, Cox shifted KCJZ’s programming to rhythmic oldies under the brand "106.7 JAMZ," highlighting classic disco, R&B, and Motown favorites.
By August 2001, KCJZ had transitioned into a Rhythmic/Dance Top 40 format while maintaining the "Jamz" branding and call letters.
Contemporary Hits Transition
At 10 a.m. on October 31, 2003—immediately following Michael Jackson’s "Thriller"—KCJZ flipped formats to mainstream Top 40 as "Z 106.7," adopting new call letters KELZ. The inaugural song was "Where is the Love?" by The Black Eyed Peas. This move introduced a second mainstream Top 40 competitor in San Antonio against Clear Channel’s KXXM. Initially, KELZ offered an expansive playlist aimed at listeners drawn to KXXM’s modern rock-leaning selections.
Power 106.7
On October 6, 2006, the station reverted to a rhythmic contemporary format, rebranding as "Power 106.7" and changing its call sign to KPWT. This reintroduction marked the first Rhythmic competition in San Antonio since 2003, positioning KPWT as a challenger to the leading KBBT. Notably, KPWT became the second San Antonio outlet to adopt the "Power" moniker, which was previously utilized by KITY between 1987 and 1990.
FM Talk
At noon on May 28, 2009, KPWT began a stunt featuring Christmas music under the name "Santa 106.7." Shortly thereafter, on June 1, it launched "FM Talk 106.7," showcasing personalities such as Mancow Muller, Neal Boortz, Laura Ingraham, Michael Savage, and Clark Howard. This programming shift anticipated the rollout of Portable People Meters (PPM) in San Antonio's ratings system. Despite Cox Media Group’s successes with FM talk formats in other regions, poor audience numbers led to the format's discontinuation within a year.
World Class Rock
Beginning April 1, 2010, KPWT initiated a stunt with ticking clock sounds, announcing a format reveal scheduled for April 5 at 5 p.m. The station then debuted an Adult Album Alternative format focused on classic material under the brand "X106.7, World Class Rock," opening with Talking Heads’ "Take Me to the River." Operating without DJs and relying on automation, KPWT emphasized classic alternative and rock tracks to distinguish itself from the more aggressive KZEP. Most talk programming migrated to Clear Channel’s KRPT on April 15; subsequently, KPWT updated its call letters to KTKX on April 20 to better reflect its new identity.
This represented San Antonio’s second venture into AAA programming following KMFR "103.7 Mighty Fine Rock" (2001–2004), now KAHL-FM with an Adult Standards format.
Classic Rock
On November 15, 2010, KTKX transitioned to a pure classic rock format aimed at competing directly with KZEP, branding itself as "San Antonio's Most Commercial Free Classic Rock." In June 2014, Cox Media Group introduced alternative rock stations using the "X" brand in Orlando (WCFB HD-2) and Atlanta (WTSH), building on similar formats in Tampa Bay (WSUN-FM) and Jacksonville (WXXJ). These launches fueled speculation that San Antonio’s "X106.7" might shift toward alternative rock, potentially becoming the market’s inaugural mainstream alternative outlet.
Nonetheless, on August 8, 2014, rival KZEP moved its classic rock format to an HD-2 subchannel and translator while unveiling a Rhythmic Contemporary format called "Hot 104.5" on its primary frequency. In reaction to this change, KTKX discarded the "X" branding and adopted the name "106.7, The Only Classic Rock Station You Can Hear Everywhere in San Antonio." One week later, it embraced the slogan "106.7 The Eagle, San Antonio's ONLY classic rock." Alternative rock returned to the San Antonio market through Alpha Media’s "103.3 The App," broadcast via translator K277CX and KTFM's HD2 subchannel until 2017.
