 KMRT was the first radio station in America to air the Banda format all the time.It operated with an automated Audio Server delivery system.Eventually, the call sign changed to KDXX (1998–2002), and KHCK (1998–2005), a simulcast of Tejano KHCK-FM "Kick FM" until the FM changed format to Cumbia music as KFZO and the AM continued as a stand-alone Tejano station for a few months.
