KSKO is rebroadcast on Class D FM repeaters full time in Grayling, Shageluk, Holy Cross, Nikolai, and Anvik.
[2][3] Two new "repeaters" were built in the summer and fall of 2021, KSKC Crooked Creek and KSKP Sleetmute which added 200 people to KSKO's "population served" count for a total of about 1,200 on owned and operated repeaters/signals across a stretch of 200 miles or so along the west central interior.
[4] The station began broadcasting on July 1, 1981, initially on a frequency of 870 kHz on the AM dial.
Station owners Kuskokwin Public Broadcasting Corporation switched from AM to FM in 2015.
KSKO holds the annual "Back to Bluegrass" music festival in McGrath, which is held in June or July featuring local and regional musicians.
