[3] Licensed to Coleraine, Minnesota, United States, the station serves the Iron Range area.

Established in 1995 as KGPZ, the station is owned by Midwest Communications.

The station now directly competed with WUSZ (99.9 FM).

On January 1, 2017, as a result of a sale between Red Rock Radio and Midwest Communications (Midwest acquired KGPZ in the sale), 96.1 adjusted their format to classic country, as "96.1 Duke FM"; the sale essentially turned KGPZ from a rival to WUSZ into a flanker for it.

[5] On January 30, 2017, KGPZ changed their call letters to WDKE, to go with the "Duke FM" branding.
