WHME, the flagship station of LeSEA, was the original host of the Christian contemporary music festival that is now known as the World Pulse Festival, which began as a free concert to celebrate WHME's 19th birthday in 1987.^[1][2] On December 9, 1996, WHME's Christian contemporary music format moved to WHPZ 96.9 FM.^[2] In 2018, WHME returned to its Christian contemporary format as a simulcast of Pulse FM, and its former talk and teaching format moved to the HD2 side channels of all three Pulse stations.
