WBHR (660 kHz) is a commercial AM radio station licensed to Sauk Rapids, Minnesota, and serving the St.
Because 660 AM is a clear channel frequency reserved for Class A WFAN New York City, WBHR reduces power to 500 watts at night to avoid interference.
The station uses a directional antenna at all times, and their transmitter array is located on 10th Avenue NE near Golden Spike Road in Sauk Rapids.
[4] On July 2, 1962, the Tri-County Broadcasting Company, owned by Carl A. Nierengarten and Herb Hoppe, received a construction permit from the Federal Communications Commission (FCC).
It authorized Tri-County to build a new radio station on 800 kHz in Sauk Rapids, to broadcast with 250 watts as a daytimer.
Hoppe, unsure of how the venture would turn out, designed the radio station studio building, a former barn, to be convertible to a house, in case the business failed.
[8][7] He also sold ad time, served as a disc jockey and hosted concerts headlined by such artists as Dolly Parton and Porter Wagoner.
Then three years later, after the FCC opted to break down several clear channel frequencies, Hoppe filed to move the station to 660 kHz to allow for an additional signal boost.
[20] The station's daytime signal reaches 4 states, providing at least Grade B (fringe) coverage to the Twin Cities, as well as locations such as Wadena, Alexandria, Detroit Lakes, Bemidji, and Duluth, as far west as Milbank,[21] and New Effington[22] in South Dakota and Wahpeton,[23] and Fairmount[24] in North Dakota and as far east as Menomonie,[25] Cedar Falls,[26] Bennett,[27] and Superior[28] in Wisconsin.
