KCJJ originated as an application for a new station on 1560 kHz in Iowa City, which was filed in 1971, but was not issued a construction permit until 1976. The station began regular broadcasting on January 15, 1977.
Expanded Band assignment On March 17, 1997, the Federal Communications Commission (FCC) announced that 88 stations had been given permission to move to newly available "
Expanded Band" transmitting frequencies, ranging from 1610 to 1700 kHz, with KCJJ authorized to move from 1560 kHz to 1630 kHz. A construction permit for the expanded band station was assigned the call sign KCJK on November 10, 1997. The two stations swapped call signs on October 3, 1998, with AM 1560 changing from KCJJ to KCJK, and AM 1630 changing from KCJK to KCJJ. FCC policy provided that original stations and their expanded band twins could operate simultaneously for up to five years, after which owners would have to turn in one of the two licenses. It was decided to transfer full operations to the expanded band station, and on May 7, 2002, the license for the original station on 1560 kHz (KCJK) was cancelled, with AM 1630 continuing as KCJJ. ==References==
