KHDK (97.3 FM "Hot 97.3") is a Top 40 (CHR) radio station based in Burlington, Iowa, United States.

Before CHR made its 2006 debut in the Burlington-Fort Madison area on 97.3, the station was known as KKNL (K K New London).

KKNL was actually a simulcast of 93.5 KKMI to provide a better signal to Mount Pleasant, as the 93.5 signal is hard to receive in the Mount Pleasant Area.

The simulcast lasted for four years, until late-2005 when KKNL broke away from KKMI, emerging as the Tri-States New Hit Music Channel: Hot 97 dot 3.

The station airs The Kidd Kraddick Morning show weekday mornings followed by Hayden Roberts (10a-3p), Kara (3pm-7pm), and XYZ with Erik Zachary (7pm-mid)
