KTKX (106.7 MHz "106.7 The Eagle") is a commercial FM radio station, licensed to Terrell Hills, Texas, and serving the San Antonio metropolitan area. KTKX is owned by Cox Radio, positioned between two other Cox stations. KTKX has a pop-leaning classic rock radio format, while sister stations 99.5 KISS-FM airs an active rock format with some harder-edged classic rock titles, and 101.1 KONO-FM plays classic hits, including some classic rock songs that also scored on the Top 40 charts.

KTKX's studios and offices are located on Datapoint Drive in Northwest San Antonio near the South Texas Medical Center complex.[1] The transmitter site is off Hallmark Path in southern Bexar County.[2] KTKX has an effective radiated power (ERP) of 100,000 watts, the maximum power for non-grandfathered FM stations. It broadcasts in the HD Radio format.


106.3 KTUF and KESI[edit]

Before 1979, KBUC-FM (now KVBH) was heard on 106.3 in the San Antonio radio market. In 1979, it moved to 107.5, clearing the way for a new station to go on the air at 106.3. KTUF signed on the air on July 18, 1979.[3] It was San Antonio's first commercial FM radio station with a jazz format. KTUF was the FM counterpart to AM 1480 KAPE (now KCHL). Both stations were owned by the Southern Sound System Broadcasting Company. KTUF broadcast at only 3,000 watts, because FM 106.3 was originally a Class A frequency, reserved for lower-powered stations.

In 1982, the station was acquired by S.I.T. Broadcasting. The following year, the format changed to album rock with station taking the KESI' call sign. Then it tried easy listening music, followed by an adult contemporary music format known as "Star 106." But ratings on all of these formats underperformed, in part due to the station's low power.

Move to 106.7[edit]

In 1986, KESI switched frequencies from 106.3 to 106.7 FM.[4]. Moving to 106.7 was coupled with a big boost in power, going to 100,000 watts. The next year, KESI switched call letters to KMMX, becoming "K-Mix 106.7." But it kept its AC format intact for several more years.

On November 1992, KMMX flipped to a simulcast of country music formatted AM 680 KKYX, with a change in call signs to KKYX-FM. That gave San Antonio three full power FM country stations, with 97.3 KAJA and 100.3 KCYY playing mostly contemporary country hits while KKYX-AM-FM leaned toward classic country.

The simulcast ended the following year, just in time for the 1993 San Antonio Stock Show & Rodeo. KKYX-FM switched to Contemporary Country, calling itself "106.7 The Armadillo." It took the call letters KDIL (with DIL contained within the word "armadillo," a small placental mammal common to South Texas).

Smooth Jazz[edit]

The Armadillo lasted only two years, when 106.7 switched again. The station had been bought by New City Communications, which also owned country rival 100.3 KCYY. KCYY was (and still is) in the middle of a tough ratings battle with Clear Channel Communications' 97.3 KAJA. New City did not want two of its stations airing country music and KCYY's ratings were considerably higher.

So KDIL became "Smooth Jazz 106.7 KCJZ" at midnight on February 24, 1995.[5][6] The smooth jazz format was proving successful in markets such as Los Angeles, New York City and Chicago, so New City brought it to San Antonio.

Rhythmic Oldies[edit]

In 1997, current owner Cox Communications acquired KCJZ and the other New City stations. After four years as smooth jazz, Cox changed KCJZ's format on July 1, 1999. (Smooth Jazz is currently heard in San Antonio on 101.9 KQXT's HD2 suhchannel.)

Many stations around the country were finding success with rhythmic oldies.[7] Keeping the KCJZ call letters, the station became known as "106.7 JAMZ," playing classic disco music, R&B and Motown hits.

This evolved into a Rhythmic/Dance Top 40 format by August 2001. The station still kept its KCJZ call sign and "106.7 JAMZ" slogan intact. Even though San Antonio had four stations playing some form of contemporary hits, 106.7 JAMZ did well. The station was later helped by the arrival of midday DJ Hot Herrietta and her "Noontime Workout" moving over from 94.1 KTFM. The rhythmic contemporary sound lasted two years.

Contemporary Hits[edit]

On October 31, 2003, at 10 a.m., KCJZ switched directions to Mainstream Top 40 and changed call letters to KELZ. The last song on 106.7 Jamz was "Thriller" by Michael Jackson, followed after a commercial break by the official launch of the new format as "Z-106.7." The first song played was "Where is the Love?" by The Black Eyed Peas.

This gave the San Antonio market two mainstream Top 40 stations, with Z-106.7 competing against 96.1 KXXM, owned by Clear Channel (now iHeartMedia). At first, KELZ's playlist was broad-based, airing "All The Hits" in an effort to cut into KXXM, whose direction at times tended toward modern rock.

Power 106.7[edit]

On October 6, 2006, KELZ management decided to challenge market leader "98.5 The Beat KBBT," a rhythmic contemporary station owned by Univision. Z-106.7 moved towards a rhythmic direction and adopted the "Power 106.7" branding, along with a call letter change to KPWT to match it. The move gave San Antonio its first Rhythmic battle since 2003. With the switch, KPWT became the second station in San Antonio to adopt the "Power" moniker. The last station to use the brand was 92.9 KITY from 1987 to 1990.

The format lasted until May 28, 2009. At noon, KPWT played "Love Lockdown" by Kanye West. The song has the sound of jingling bells, increasingly getting louder, followed by just the sound of the bells for about 30 seconds as the song ends. That led to KPWT began stunting with Christmas music as "Santa 106.7," even though Christmas was seven months away.

FM Talk[edit]

At 5pm on June 1, 2009, the station became "FM Talk 106.7."[8] The lineup included Mancow Muller, Neal Boortz, Laura Ingraham, Michael Savage and Clark Howard. The move behind this switch may have been the pending use of Portable People Meters (PPM) in determining ratings in the San Antonio market. Cox has had success with FM talk stations in Atlanta, Orlando, Jacksonville, Tulsa and Dayton, and decided to give the format a try in San Antonio.

The talk format did not survive a full year. On April 1, 2010 at 12 p.m., the station began stunting with the sound of a clock ticking. A voice told listeners to tune in on April 5th at 5 p.m. to find out the station's new format.

World Class Rock[edit]

The stunt ended on April 5, 2010. A classic-based Adult Album Alternative (AAA) format was launched as "X106.7, World Class Rock." The station did not use DJs. It was automated like KJXK "102.7 Jack FM," but focused on classic alternative and classic rock hits. It was not as hard-edged as 104.5 KZEP, which focused on harder classic titles from the rock era. The first song on X106.7 was "Take Me to the River" by The Talking Heads.[9] Most of KPWT's talk lineup moved to Clear Channel Communications-owned 92.5 KRPT on April 15. Five days later, on April 20, KPWT changed call letters to KTKX to go with the "X106.7" branding.

This was not the first time the AAA format was tried in San Antonio. The previous AAA formatted station was KMFR "103.7 Mighty Fine Rock" from 2001-2004 (now KAHL-FM airing Adult Standards).

Classic Rock[edit]

On November 15, 2010, KTKX turned to a straight-ahead classic rock format to compete directly with rival 104.5 KZEP. KTKX re-positioned itself as "San Antonio's Most Commercial Free Classic Rock." Throughout June 2014, Cox-owned stations in Orlando (WCFB's HD-2 feed) and Atlanta (WTSH) were heard flipping to alternative rock using the "X" name. Orlando saw the debut of "X107.3" and "X107.1" premiered in Atlanta. Each was called "Orlando's/Atlanta's New Alternative." Prior to this, Cox owned "X"-named alternative formats in Tampa Bay (WSUN-FM) and Jacksonville (WXXJ). Because of these stations, rumors spread that San Antonio would be next in line to "Join the Revolution" and switch "X106.7" to what would've been the market's first mainstream alternative station.

However, on August 8, competitor KZEP moved its classic rock format to the station's HD-2 feed and 93.3 translator, as the main channel flipped to a Rhythmic Contemporary format as "Hot 104.5." In response, KTKX dropped the "X" name that same weekend and simply called itself "106.7, The Only Classic Rock Station You Can Hear Everywhere in San Antonio."[10] On August 15, KTKX changed its slogan to "106.7 The Eagle, San Antonio's ONLY classic rock."[11] Alternative rock returned to San Antonio on Alpha Media's "103.3 The App," which is broadcast on translator station K277CX and KTFM's HD2 subchannel.
