WMIT

WMIT (106.9 MHz, "106.9 The Light") is a non-profit FM radio station licensed to Black Mountain, North Carolina. WMIT is a listener-supported ministry of the Billy Graham Evangelistic Association. It airs a mix of Contemporary Christian music with some Christian talk and teaching programs, including national religious leaders Jim Daly, John MacArthur, David Jeremiah, Chuck Swindoll and Charles Stanley. Studios and offices are on Porters Cove Road in Asheville. WMIT's tower rises above Clingman's Dome.
In 2007, WMIT began broadcasting in the HD Radio format, adding "theEdge 106.9" on the HD2 digital subchannel. It features Christian rock music for teenagers and young adults, which is also heard on translator W292CJ (106.3 FM) in Asheville. In addition, WMIT is heard on a simulcast AM station, WAVO 1150 in Rock Hill, South Carolina, and FM translators W282BP (104.3 MHz) and W268DM (101.5 MHz) in the Charlotte metropolitan area, as well as translator station W234CF (94.7 MHz) in Boone, North Carolina. Most of WMIT's schedule is also simulcast on 106.7 WFGW in the Knoxville, Tennessee radio market.
"Superpower" Coverage.
WMIT has one of the largest coverage areas for an FM radio station in the Eastern United States. It claims a potential audience of five million people in North Carolina, South Carolina, Tennessee, Virginia and Georgia. This is because its transmitter is located on Clingmans Peak, with the combined mountain and transmitter tower elevation at over above sea level, with the highest transmitter site east of the Mississippi River. 
Its effective radiated power (ERP) is 36,000 watts. Many FM stations nearby run at 100,000 watts but their towers are only a third the height of WMIT. Due to its unusual height above average terrain (HAAT), WMIT is grandfathered with a "superpower" signal. In addition to its hometown of Asheville, WMIT can be heard in the Tri-Cities of Tennessee and Virginia (where it provides city-grade coverage) as well as Greenville/Spartanburg and Charlotte. The station has begun identifying as "WMIT, Black Mountain-Charlotte-Asheville," acknowledging its large following in the Charlotte area, primarily the western portion of the market.
History.
In the summer of 1941, Mount Mitchell Broadcasters signed on W41MM, with 50,000 watts, on 44.1 MHz, within the old FM band. It is the oldest FM station in North Carolina and among the earliest FM stations in U.S. The station's transmitter was above sea level. Originally licensed to Winston-Salem, away, the station operated by remote telephone line. The Winston-Salem studios were eventually housed in a two-story building built in 1942 at 419 Spruce Street by the "Winston-Salem Journal" and "The Twin City Sentinel" for their AM station WSJS.
W41MM became WMIT, and moved to 97.3, when the FM dial moved to 88-108 MHz. Sometime before 1950, WMIT switched to 106.9 MHz and relocated its studios and city of license to Charlotte.
Its transmitter rises above on Clingmans Peak, putting WMIT tower's light higher than anything else east of the Mississippi. The station's call letters stand for Mount Mitchell, the highest mountain east of the Mississippi River, located about 2½ miles northeast of the station's transmitter. The two-story building housing the transmitter equipment included living space for station engineers needing to stay during difficult winter weather when the road to the top might be impassable. Diesel engines powered the station at first, but eventually power lines were installed.
Gordon Gray had to close the station in Spring 1950 because he did not have the time to run it. When the station returned to the air in 1951, its power was the equivalent of 325,000 watts. WMIT could be picked up in Atlanta, Georgia, away. Six and a half million potential listeners could receive the signal. Studios were in Charlotte, away, and programming was delivered by means of an STL. Much of the music was classical or beautiful music, though three hours a day of local, regional music was played due to listener interest.
Billy Graham's ministry purchased WMIT in 1962. At first Graham used the station to broadcast Christian instructional and preaching programs, hosted by Graham and other religious leaders. But around 2000, the station shifted its focus to airing a music-oriented Christian contemporary format, with some instructional and preaching programs during the day.
