KDHX

KDHX (88.1 FM) is a non-commercial radio station in St. Louis. Owned by Double Helix Corporation, the station primarily airs adult album alternative music. It broadcasts from studios on 3524 Washington Blvd. in the Grand Center Arts District, while its transmitter is located on Fairfax Avenue in Arnold, Missouri.

The station previously aired an array of community radio shows, including specialty music, cultural and public affairs programming. KDHX's operations began to decline in the 2020s, following accusations of mismanagement by current and former volunteers of the station, and a resulting decline in revenue from donations. Amid these issues, the station laid off all its volunteer staff in January 2025 and filed for bankruptcy in March, with the station having since been broadcasting on an automated basis with no live programming. After a bidding war between two Christian radio broadcasters, Gateway Creative Broadcasting was awarded the right to purchase the station in an auction conducted by the bankruptcy court.
