WFAA (AM) was initially based its operations in a 9×9-ft tent on the roof of the "Dallas Morning News" headquarters, before relocating to the newspaper's library. On October 1, 1925, it later moved to the 17th floor of the Baker Hotel at the southeast corner of Commerce and Akard Streets in downtown Dallas (which would be demolished in 1980), and then moved to facilities atop the Santa Fe Railroad Warehouse on Jackson Street on June 20, 1941 (the building still has the "WFAA" calls clearly painted along a panel on the top floor). On April 4, 1961, it moved to the WFAA Communications Center at Young and Record Streets. On July 2, 1983, its call letters were changed to KRQX.
