Before that date, it was "16Kicks" KCKK and played classic country music. The format was moved to another station in the market, which had been KYOL. (KCKK is now an adult hits station, branded as the "Rock".)
The 1600 kHzfrequency was originally assigned the call letters KLAK in 1955. The station played country and Western music. In 1966, they opened a new transmitter and also began broadcasting on the FM band at 107.7 MHz. The FM station is now KQKS (now at 107.5), also owned by Lincoln Financial Media. According to the Federal Communications Commission (FCC), other call signs for this station have been KRXY, KWMX, and KYGO (the first two being simulcasts of their FM counterparts on 107.5).
On December 8, 2014, Entercom announced that it was purchasing Lincoln Financial Group's entire 15-station lineup (including KEPN) in a $106.5 million deal, and is set to operate the outlets under a LMA deal until the sale is approved by the FCC.
