KLKK (103.7 FM, "The Fox") is a classic rock formatted broadcast radio station licensed to Clear Lake, Iowa, serving Clear Lake, Mason City and surrounding areas of North Iowa and Southern Minnesota.

"[2] The change to "103.1 The Fox" and KLKK call letters took place on August 1, 1990, after being sold to Linder Radio Group.

[4] In January 1993, James Ingstad Broadcasting bought KLKK, and became co-owned with KGLO and KIAI.

[9] Due to market ownership limits, as Three Eagles already owned KLSS, KRIB, and KYTC, KLKK and KSMA-FM were immediately spun off to Coloff Media, which is based in nearby Forest City, along with their Charles City and New Hampton stations KCHA, KCHA-FM and KCZE.

Its staff includes James Shaman, Mark Skaar, Harry O'Neal and Rob Getz.
