WKNW (1400 AM) is a news/talk radio station serving Sault Ste. Marie, Michigan and Sault Ste. Marie, Ontario, Canada. The station is the only dedicated privately owned news/talk station in the market, save for its tenure as an ESPN Radio affiliate from 2010-2022. According to past editions of the Broadcasting Yearbook, the station went on the air as WKNW in August 1990, after briefly holding the callsigns WBPW and WDHP before launch. The station was popularly known as KNOW AM in the 1990s, which alluded to its news/talk format, and also served as an antonym (in name and frequency) to sister station WYSS' Yes FM branding.
