AM 1320 CHMB is a Multicultural station in Vancouver, British Columbia airing Chinese programming through the week and a dozen other languages on weekends. The station signed on the air in December, 1959 as CHQM and for the next 30+ years carried different brands of a Nostalgia/Easy Listening/Lite Rock format. New owners took over in 1994 after which they flipped to their current call letters and Ethnic format. Although the sticker says "Since 1973," nothing in their history or Wikipedia page indicates anything special about that year. Anyone know differently?
