KDEC (1240 kHz) is a commercial AM radio station broadcasting in Decorah, Iowa. KDEC airs an adult contemporary format branded as "The River".
KDEC broadcasts on a frequency shared with local non-commercial college radio station KWLC.
In 1926, Decorah's first radio station started broadcasting from the south end of the second floor of the Ben Bear building, with Charles Greenley the announcer.
