WKPK (88.3 FM, "Smile FM") is a radio station which is part of the Smile FM radio network licensed to Michigamme, Michigan. It was licensed on July 22, 2008, to operate on 88.3 MHz with 15 kW. The station broadcasts from the same tower used by WFXD and WKQS in Marquette, Michigan. WKPK broadcasts Smile FM programming from flagship station WLGH in Lansing. WKPK is owned by Smile FM.
The original construction permit called for the station to transmit from a tower closer to Michigamme with 100 kW on 88.1 MHz. On October 26, 2007 a modification of the original construction permit was granted to move the station northwest of Marquette on 88.3 MHz with reduced power from a much higher tower. During final station construction the antenna height was reduced by 12 meters to avoid other antennas on the same tower.
The call letters WKPK were used for many years by WSRT 106.7 in Gaylord, Michigan.
