KXTN was the "original" all Tejano station, and even when it launched the success of Tejano was an accident: they got a huge FM signal and a bad AM daytimer. So they put Tejano on the AM as fill. The FM, using the common Latino AC format of the 80's, was beaten out of the gate by the lousy AM. They swapped formats and the FM became all Tejano.
I remember the old K-Suave 107.5 and "Lock it in, and crank it up. Tejano 1310 KXTN!" Seems like it was early '91 when the formats swapped. KZVE 1310 only lasted a couple more years, though that was probably because of the new station down the hall. Tichenor attempted to do the Latino AC after it bought 92.9 from what became Secret Communications in '93, and it might've lasted three years before becoming "Estereo Latino." I seem to remember Tichenor had originally planned on doing Tejano on 92.9, but TK was looking to cash out its investment in radio after duopoly had become legal. When it found out KXTN was for sale, it made an offer.
There was a lot of heritage in the cluster to keep the format, but most of the reasoning for retaining it was community pressure by civic and government leaders. When it moved to AM, billing was horrible. We had tried a variety of different mixes and spent a couple of hundred thousand in research... nothing would keep it from being a 45+ format and nothing would produce new music.
I remember you saying that, by around 2005, the vast majority of revenue from KXTN was coming from its mostly talk morning show.
Outside of the blip-on-the-radar burst of national attention the music got in 1995 when its biggest star, Selena, was murdered. It made the news in all 50 states, and got people in 49 of them curious about who Selena was and what made her such a star. She had one crossover hit, "Dreaming of You," which got considerable adult contemporary airplay.
"I Could Fall in Love" was also played on AC and CHR, at least in Texas. Don't know how well it did nationwide, but I remember hearing it on Casey's Top-40 and the Rick Dees Weekly Top-40. It couldn't have done that just based on Texas airplay, but I couldn't tell you how many spins it got outside the state.
For those not familiar, that “bad AM daytimer” was previously KBUC 1310, which had been Country for a number of years. KBUC-FM 107.5 was its sister station. Both were flipped under new ownership.
That was either '86 or '87 when KBUC AM/FM became KXTN and KZVE. Seemed like a strange format change at the time, but KBUC was the stodgy old country station that wasn't sold out if it was playing music and had been struggling to compete against the "more music, fewer commercials" approach KJ-97 and Y-100 were using. Class 100 flipping to country as Y-100 was quite shocking at the time, too, but no one can argue it didn't work. Not sure who sold KBUC AM/FM to TK Communications, but it was owned by Sigmor, which was an oil company, in the 70's and early 80's. I don't remember all the details about KBUC, but, looking back, it reminds me a lot of the Great Empire stations.
The KXTN-FM Tejano format did have an imitator in Houston with KXTJ 107.9 in the mid 90’s, which was a direct competitor to KQQK. Both eventually fell under common ownership, and the formats were combined. Tejano eventually fizzled, and both frequencies have gone through several changes over the years, but are still Hispanic targeted.
We had a couple in Dallas, too, though only Kick FM even came close to covering the entire market. Even then, it had three FM's at one time with plans to launch a fourth. It tended to cover the surrounding area better than it did the middle of the market. Seems like the first DFW station to try the Tejano format was 1540, which was previously religious KSGB, as KTNO. It might've lasted longer than a year, but I don't think it lasted two. Kick FM lasted about 10 years in total on various signals, but it was at least gone from FM by 2004. Seems like it might've continued on 1480 for a few years afterward, but it was eventually dealt to Salem. Texas still has a few Tejano stations, but most are either on poor signals or in small markets. As you might remember, Alpha flipped one of its San Antonio signals to Tejano and brought back Jhonny Ramirez, who had been working in San Angelo since being let go from KXTN. Seems like the Tejano station in San Angelo where Jhonny had been working is still doing the format, too. Tejano would seem to be most successful in Laredo and Corpus, though I have no idea what 92.7 Laredo and 99.9 Corpus are billing these days.
