KJAM has been a cornerstone of local broadcasting in Madison, South Dakota since its launch in 1959. Originally operating as KJAM-AM 1390, the station quickly became a trusted source for news, weather, sports, and music for listeners across Lake County and the surrounding region.

For decades, KJAM-AM built its reputation on community-focused programming and a classic hits format, featuring favorites from the 1970s and 1980s. Its strong local presence, including coverage of high school sports and regional events, made it a daily habit for generations of listeners.

As listening habits evolved and audiences increasingly turned to digital and multi-platform access, the station embraced a broader identity beyond the AM dial. Rebranding to simply KJAM Radio, the station expanded its reach through online streaming and modern platforms while maintaining its roots in terrestrial broadcasting.

Under Christensen Broadcasting ownership, KJAM Radio continues to honor its legacy of local service while adapting to the future of radio. Today, it remains “Madison’s Best,” delivering classic hits, local news, and community connection—now accessible anytime, anywhere.
