KLXX (1270 AM), known as "Super Talk 1270", is a radio station located midway between Mandan and Bismarck, North Dakota, USA. It has always been licensed to Mandan, although most of its audience is in neighboring Bismarck.
The station was founded in 1926 as KGCU by the Mandan Radio Association and initially broadcast at 1250 on the dial. It is believed that the "GCU" portion of the original call letters stood for the initials of George C. Underwood, a member of the founding group. After re-branding to KBOM ("K-Bomb") in the mid-1950s, the station went through several formats and owners, and for a short time between March 1974 and the assignment of KLXX, it was KWWB.
Townsquare Media also owns KACL 98.7 (Oldies), KBYZ 96.5 (Classic rock), KKCT 97.5 (Top 40), and KUSB 103.3 (Country) in the Bismarck-Mandan area. All the studios are at 4303 Memorial Highway in Mandan.
