* Broadcasts of police reports and wanted persons information began in June 1921. The reports were given every evening at 7p, and were sometimes followed by phonograph music.
* The Dept. of Commerce licensed WRR as a commercial land station on Aug. 4, 1921.
* Officially licensed by the Federal Radio Commission on March 13, 1922 (the date many historians trace the station to, which is why it doesn't show up with a higher rank on many "oldest stations" lists.)
* WRR resurrected from the dead - The Dept. of Commerce mandated technical upgrades to radio transmitters (many of which were homemade) in 1925. The City was unable to afford the upgrades required for WRR's 200 watt transmitter and turned in the license in July 1925. Local radio fans were outraged, and the Morning News (WFAA) and Time Herald (KRLD) newspapers helped raise the necessary funds to put WRR back on the air, which finally happened on Oct. 15, 1925.
