KDZR (1640 AM) is a commercial American radio station, licensed to Lake Oswego, Oregon, and serving the Portland metropolitan area.

[10][11] On September 15, the Salem Media Group announced it would acquire the last five Radio Disney owned-and-operated stations still available for sale, including KDZR, for $2.225 million.

[17] The move coincided with Salem beginning a local marketing agreement (LMA) to operate and program another Portland-area conservative talk station, KPAM Troutdale, which began calling itself "AM 860 The Answer".

[18] KDZR previously aired nationally syndicated shows, primarily from the Salem Radio Network, including Mike Gallagher, Hugh Hewitt, Larry Elder, Jay Sekulow and Joe Walsh.

[citation needed] In addition to KDZR, Salem also operates another conservative talk station in the Portland radio market, AM 860 KPAM Troutdale.

Some Salem Radio Network shows that are not carried weekdays on KDZR are heard on KPAM, including Dennis Prager, Sebastian Gorka and Michael Medved.
