KTTU-FM (97.3 FM, "Double T 97.3") is a radio station serving the Lubbock area. KLZK was originally on 104.3. On March 30, 2008, KLZK-FM swapped frequencies with sister station KSTQ-FM.
97.3 was activated in 1961 as KPLA (FM) Plainview, Texas. It operated separately from sister station KVOP (AM). KPLA raised power to 100,000 watts at 500 feet in 1976. Call letters changed to KATX at the same time.
As part of a format change to News/Talk/Sports in October 2003, simulcasting KJTV-AM, RAMAR built an 800-foot tower near Petersburg, Texas. That tower fell in a small plane mishap in 2004 and was replaced. In late March 2008, RAMAR executed a Construction Permit to change 97.3 from a class C1 to class C2, and change the city of license from Plainview to New Deal, Texas. RAMAR also abandoned the Petersburg tower to relocate 97.3 into the Lubbock metro, broadcasting from the KJTV-TV tower at 98th and University.
KLZK was also known as KISS 104.3 FM and the format was a Hip-Hop and R&B station. At this time it was licensed to the city of Brownfield, TX.
At the end of 2007, RAMAR Communications received a Construction Permit to change the city of license for KLZK from Plainview to New Deal and to move its transmitter site from the Petersburg Tower to the RAMAR Tower at 98th and University Avenue in Lubbock.
On September 12, 2011 KLZK, after a weekend of stunting, changed their format to hot adult contemporary, branded as "97.3 Yes FM".
On December 18, 2015 at 10AM, as part of a 5-way radio station swap, 97.3 and 104.3 swapped formats again, as YES FM moved to 107.7 KLBB-FM and 104.3's sports format moved to 97.3 as "Double T 97.3".
Also, 97.3 (became KTTU-FM on December 29, 2015) became the new flagship station for the Texas Tech Sports Network. Double T 97.3 will air Texas Tech Football, Men's Basketball and Baseball games. As part of the swap, RAMAR's 93.7 The Eagle will no longer broadcast Texas Tech Football and Men's Basketball games.
