On November 11, 1928, under the provisions of the Federal Radio Commission's "General Order 40", WKBP was assigned to 1420 kHz."Broadcasting Stations, by Wave Lengths, Effective November 11, 1928", Commercial and Government Radio Stations of the United States (Edition 6/30/1928), page 175. On March 12, 1930, the station changed its call letters to WELL. (Local resident John Harvey Kellogg was famous at this time for promoting "the road to wellness" at his sanitarium) In March 1941, the implementation of the North American Regional Broadcasting Agreement resulted in nearly all the stations on 1420 kHz being moved to 1450. However, WELL was an exception, and instead shifted to 1400, where the station has remained ever since. An FM sister, WELL-FM (now WKFR-FM), was added in June 1963, originally at 96.5 mHz but soon moving to 103.3.
