In September 1977, KWMB was granted permission to operate at a pre-sunrise authority power level of 500 watts, allowing it to sign on two hours before local sunrise.

In November 1985, Borgen agreed to sell KWMB to Interstate Communications, a company headed by John Meisch, Jr., who served as president and general manager.

In June 1990, Interstate Communications decided to sell KWMB and the construction permit for sister FM station KMFX-FM to Radio Ingstad Minnesota, for $275,000.

[1] Clear Channel kept KMFX dark for a period of about three years, when it donated the station to a non-profit group, Minority Media and Telecommunications Council, based in Washington, DC.

Upon the consummation of the sale to Q Media on June 15, 2011, the station resumed regular broadcast operations, changing its call sign to WBHA.

On July 9, 2013, Q Media acquired an FM translator at 99.7 from Faith Sound, Inc., for $75,000, and signed on with WBHA's programming a short time later.
