KISD 98.7 FM traces its roots back to the mid-1970s, when Wallace Christensen acquired KLOH-AM and KLOH-FM in 1976 from Ingstad Broadcasting. This acquisition marked the beginning of what would become a long-standing family-owned broadcasting presence in southwest Minnesota and the Sioux Falls radio market region.

For the next decade, KLOH-AM and KLOH-FM operated as a simulcast, providing consistent programming across both AM and FM signals. During this era, the stations focused on a broad-based music and community service format, serving listeners across Pipestone and surrounding communities.

In 1987, a major programming and branding shift took place. The FM station broke away from the AM simulcast, marking a new independent identity for the frequency. At that time, the station adopted new call letters – KISD – and launched a dedicated oldies format under the branding that would become known as “The Oldies Channel.”

This transition positioned KISD as a standalone FM music station focused on classic hits from the 1960s, 1970s, and early 1980s. The format quickly built a loyal audience, emphasizing familiar, feel-good music alongside local presence and community connection.

Throughout the following decades, KISD remained under Christensen family ownership, continuing to evolve within the classic hits and oldies space while maintaining a consistent identity in the Sioux Falls market area. Unlike many stations that changed hands through industry consolidation, KISD remained part of a locally owned, multi-generational broadcasting operation.

Today, KISD 98.7 FM continues to operate as “The Oldies Channel,” carrying forward its legacy of timeless music, local connection, and long-standing family ownership under Christensen Broadcasting.

In January 1955, the Federal Communications Commission granted permission to Pipestone Radio Corporation, C.B. Thomas, President, to construct a radio station with a power of 1,000 watts on 1050 kilocycles with the call letters of KLOH (“Land of Hiawatha”) In June of 1955, Dalton Nelson, station manager, put KLOH on the air.

In the early years, KLOH broadcast during daylight hours only. The first studio location was downtown Pipestone in a basement of a building next to the old Eagle Cafe. In 1961 the studio was moved to its present location west of Pipestone on Highway 30 at the twin towers site. In 1962, KLOH was purchased by Ingstad Corporation of Valley City, ND, Bob Ingstad Sr. President.

In 1965 Wallace Christensen took a position as an announcer, became Sales Manager, and then by 1972 was General Manager. In August 1976 he purchased the station from the Ingstads and is the present owner. During these years, KLOH has had major upgrades. One of the twin towers was moved and power was increased from 1,000 watts to 9,000 watts. Coverage was increased and KLOH started broadcasting in Stereo and 24 hours a day.

In 1980 a major building project was completed more than doubling the studio and office space. In May of 1998 a complete upgrade was done with the front office traffic and billing system computers.

In 2008 a major remodeling project made the building handicap accessible.
