 KDZR's format was switched to conservative talk, branded as "Talk 1640".On April 2, 2018, KDZR made some adjustments to its program schedule and rebranded as "AM 1640 The Patriot".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."
