KDRB, "100.3 The Bus," is an adult hits radio station similar to Jack FM serving the Des Moines, Iowa, area in the United States. It broadcasts at 100.3 FM. The station's studios are located at 2141 Grand Avenue in Des Moines along with iHeartMedia, Inc.'s other Des Moines stations (KDXA, KKDM, KXNO and WHO). Its strong 100,000 watt signal stretches north to Mason City, Iowa (which is about 100 miles from Des Moines) and south to the Missouri and Iowa border.
In 1948, WHO-FM began transmissions at 100.3 FM as the third FM station to serve the Des Moines market, after KRNT-FM and KSO-FM. In its early years, it primarily simulcast its sister station, WHO. Studios were located at 1100 Walnut Street in downtown Des Moines and the station's tower and transmitter were located on top of the Equitable Building at 6th and Locust in Des Moines. In 1950, the transmitter was moved to a new tower at WHO's transmitter site in Mitchellville, Iowa. The old transmitter and tower on top of the Equitable Building was sold to KCBC for their new FM station KCBC-FM. In the mid-1960s, WHO-FM ceased simulcasting its AM sister and started programming easy listening and classical music.
In 1973, the station underwent some dramatic changes. The call letters were changed to KLYF and the station was reprogrammed with a beautiful music format in FM stereo. This was the first time that the station broadcast in multiplex stereo and became known by its nickname "K-Life". In 1981, the format evolved into an adult contemporary format and by the mid 1990s it was an adult top 40 station competing directly with KSTZ. The station's transmitter was eventually moved to the WOI Tower near Alleman, Iowa.
