KDUK-FM (104.7 MHz) is a commercial Top 40 (CHR) music radio station in Eugene, Oregon (licensed to Florence) that serves the Eugene–Springfield, Corvallis–Albany–Lebanon, and Salem areas of the Willamette Valley. The station focuses strongly on today's hits, but occasionally plays songs dating back as far as the early 1990s. KDUK-FM plays these “old school” hits every weekday during the noon hour in a segment they call the Old School Lunch.
