KJCK (1420 AM) is a radio station broadcasting a classic hits format and is licensed to Junction City, Kansas, United States.
The station is currently owned by Eagle Communications, and previously featured programming from ABC Radio, Sporting News Radio and Westwood One.
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 KJCK authorized to move from 1420 to 1680 kHz.
On October 6, 2011, Platinum Broadcasting announced it was ceasing operations, and that the station, along with its sister stations, would be sold to Hays-based Eagle Communications, pending FCC approval.
After stunting with Christmas music, on December 27, 2018, KJCK flipped to classic hits, and began emphasizing their translator K300DN (107.9 FM).
