the Flags Over Texas observation deck on June 21, 2006. The restaurant rotates slowly, and observation deck entry is included in the cost of a tower ticket. In September 2007, Landry's converted the Eyes Over Texas Restaurant into one of its Chart House outlets. Prior to Landry's, Frontier Enterprises (owner of San Antonio-based Jim's Restaurants) operated the tower of the Americas' restaurant for more than three decades. Tower heights 750 ft (229 m) to top of the antenna. 622 ft (190 m) to top of roof. 579 ft (176 m) to indoor observation deck. 560 ft (170 m) to outdoor observation deck. 550 ft (168 m) to restaurant and stationary level. FM radio Since 1970 the roof has hosted a tapered steel mast, used as support for three FM antennas; 101.9 KQXT (then known as KCOR-FM), 102.7 KJXK (then KTFM), and 104.5 KZEP (then KITE-FM). In 2007, the three individual antennas were replaced by a 16-bay master antenna that radiates all three FM signals including the HD signal for KQXT. Clear Channel Radio and Electronics Research Inc. headed up the project along with their contractors and involved the City of San Antonio and Landry's Restaurants. The new antenna system improved coverage for all three radio stations. An option existed for several years to add facilities for a move in signal on 97.7 (requiring rearrangement of ten other stations) to share the site. This was organized by Bret Huggins and David Stewart of Rawhide Radio, LLC (partly owned by Hispanic Broadcasting now Univision radio). Transmitters are located between the public areas of the observation deck and the revolving restaurant in equipment bays along with air conditioners and plumbing. Trivia The fastest recorded time up the tower's 952 steps is 5 minutes 18 seconds on January 29, 1981.
