KBMX (107.7 FM, MIX 108) is a commercial radio station licensed to Proctor, Minnesota, and serving the Duluth-Superior radio market. It is owned by Townsquare Media and it airs a top 40 (CHR) radio format. Along with three sister stations, KBMX has its offices and studios at 14 E. Central Entrance, on the west side of Duluth.

KBMX is a Class C2 station. It has an effective radiated power (ERP) of 7,700 watts. The transmitter is on Observation Road in Duluth, amid the towers for other FM and TV stations.

The station signed on the air in 1994; 31 years ago (1994). Its original call sign was KUSZ. It started out with a country music format simulcasting WUSZ 99.9. Then it was known as "Z-Rock," airing a classic rock format. It later flipped to adult contemporary as "The Point".

After becoming a Hot AC station as Mix 108 on April 1, 2002, the station gradually evolved to a Top 40 (CHR) sound. The station had aired Open House Party on weekends. For a time, it had Top 40/CHR competition from WWAX "92.1 The Beat". That station is now "Sasquatch 92.1" airing classic rock. It then got Top 40/CHR competition from KDWZ (now classic country KDKE "102.5 Duke FM") and Hot AC WWAX as "Nu 92" (now classic rock WWPE).

These days, Mix 108 serves as one of two Top 40 stations for the Duluth-Superior area, competing against AM 970 and FM 98.1 WDUL "Hot 98.1".
