The station was founded by Dr. Ralph Poteet, former MISD Superintendent, to present community information in a way not possible via commercial radio stations, and to provide MISD students having interest in radio and communications with hands-on radio experience. The air staff is primarily made up of students from the five high schools in the city taking radio production classes.
The station signed on the air September 4, 1984, on 88.3 FM with 3,000 watts on a 250-foot (76 m) tower. It moved to 88.5 and increased its power to 61,000 watts in 1992 upon the completion of a new 415-foot-tall (126 m) City/School Communications Tower at Mesquite Memorial Stadium. 
KEOM airs live broadcasts of high school sports from MISD schools, as commentated by instructors and students enrolled in the sports broadcasting course. The station also broadcasts music from the 1970s.
