Expanded Band assignment and deletion

On March 17, 1997, the Federal Communications Commission (FCC) announced that eighty-eight stations had been given permission to move to newly available " Expanded Band" transmitting frequencies, ranging from 1610 to 1700 kHz, with KKSO authorized to move from 1390 to 1700 kHz."FCC Public Notice: Mass Media Bureau Announces Revised AM Expanded Band Allotment Plan and Filing Window for Eligible Stations"
(FCC DA 97-537), March 17, 1997. A construction permit for the expanded band station was assigned the call letters

on November 12, 1997. The FCC's initial policy was that both the original station and its expanded band counterpart could operate simultaneously for up to five years, after which owners would have to turn in one of the two licenses, depending on whether they preferred the new assignment or elected to remain on the original frequency. It was ultimately decided to transfer full operations to the expanded band station, and on February 2, 2001, the license for KKSO was cancelled.FCC Station Search Details: DKKSO
