The station began broadcasting on February 14, 1965, with the call letters KNRO-FM. In 1968, the station began operating 24 hours a day, having previously signed off at midnight. In the early 1970s, the station aired a contemporary hits format. By 1975, the station had adopted a MOR format.
In 1978, the station was sold Jimmy Swaggart Evangelistic Association for $803,750. The station's call sign was changed to KMCV, and the station adopted a religious format. In 1981, the station's call sign was changed to KJOJ, and contemporary Christian music was replaced with southern Gospel music. The station also aired brokered religious programming. The slogan for KJOJ was "Houston's Joy of Jesus." During the 1980s, hosts of the station's southern Gospel programming included Bert Salas, Mike Sheeran, and Lyle Countryman. In 1989, the station was sold to Six Chiefs Company for $8 million. The station would go on to air a contemporary Christian format, as part of a simulcast with KGLF-FM in Freeport, Texas.
On December 25, 1990, the call sign KJOJ moved from 106.9 to 103.3 in Freeport, and the station's call sign was changed to KJZS. The station adopted a new AC / smooth jazz format. In March 1992, the station's call sign was changed to KKHU, and it became "You 106.9", airing a hot talk/oldies hybrid format. In September 1992, the station's call sign was changed to KKZR and the station became "Z-Rock 106.9", airing ABC Radio Networks' satellite-fed Z-Rock network from Dallas.
106.9 then began stunting with a countdown and with monikers saying "MP3 Radio" and "Radio Free Houston". In addition, the station also filed for the KZJZ call letters, which led to rumors stating that the station may return to its former smooth jazz format. On October 4, 2000, KKHT's callsign was officially changed to KZJZ and "Jazzy 106.9" signed on with Kenny G's "Songbird". However, this was only a ruse, as seconds later "106-9 The Point" signed on, with a 1980s music format, playing Simple Minds' "Don't You ". The call letters changed to KHPT on October 17, 2000.
The Zone
At 6 a.m. on November 8, 2010, KHPT changed its format to classic alternative rock as "106-9 The Zone". The Point's final song was Bon Jovi's "Wanted Dead or Alive", while The Zone's first song was Foo Fighters' "Learn to Fly". In January 2011, the station format was refocused on 1990s alternative rock, also adding some titles from the 2000s, with its slogan changed from "106.9 The Zone, Alternative Hits From the '80s & '90s" to "106.9 The Zone, Houston's Best Alternative Hits."
The Eagle simulcast
On June 20, 2011, KHPT began simulcasting sister station's KGLK classic rock programming, as "The Eagle". This is due to The Zone having low ratings, consistently ranging from 0.3-1.5. Not long afterwards, the previous 1980s-shifted adult hits format, along with "The Point" branding, was revived on the HD2 sub-channel, replacing "Pat FM", a jockless 1980s and 1990s-shifted alternative format not unlike the franchised Bob FM format.
