[2] 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 KECN authorized to move from 690 to 1620 kHz.

[4] 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,[3] although this deadline was extended multiple times.

It was ultimately decided to remain on the original frequency, and the license for KBLI on 1620 kHz was cancelled on February 7, 2006.

[5] On September 10, 2018, KEII and KEIR (under new KNBL calls) changed their format to variety hits, branded as "Cannonball 101".
