Both institutions were affiliated with the General Mennonite Conference, and the addition of an Omaha school was intended to give a boost to enrollment by being based in a larger city with more employment opportunities for its students.

Between 1963 and 1965, preparations were made to make the station possible, including the necessary Federal Communications Commission (FCC) license and the city of Omaha for permits.

In 1976, the name was changed to Grace College of the Bible, to reflect its full status as a four-year institution of higher learning.

In May 1976, the board of directors approved purchase of radio station KROA-FM in Doniphan, Nebraska (between Grand Island and Hastings).

[9] As a non-profit outreach of Grace University, KGBI-FM supported itself with occasional on air fundraisers which the station referred to as "share-a-thons."

At the time of the sale of KGBI-FM, the Grand Island operation of KROA-FM transferred ownership to a new organization, Mission Nebraska, which currently links to translator stations that cover much of the state.

KGBI-FM's license switched from non-commercial to commercial, allowing Salem to sell advertisements on the station.

On March 31, 2014, KGBI-FM rebranded as "100.7 The Fish", a branding used on many of Salem's contemporary Christian music stations.

UNWSP returned KGBI-FM to non-commercial status, with on-air fundraisers replacing the revenue from commercial advertisements.

The deal split KGBI-FM from KCRO, KOTK, and their FM translators, which Salem sold to Hickory Radio.

UNWSP operates a chain of non-commercial Contemporary Christian outlets, including stations in Minneapolis-St. Paul, Kansas City, Des Moines, Sioux Falls, and Fargo-Moorhead.

In the mid-1970s, typical programs included "Haven Of Rest," "Back to the Bible," and "NightSounds with Bill Pearce."
