WKDM 1380 is a United States ethnic brokered radio station serving New York City and owned by Multicultural Broadcasting. The station broadcasts in Mandarin Chinese, 24 hours a day from Monday to Friday. The station began operation in 1926 as WBNX, the call letters reflecting the station's location in the borough of the Bronx. It changed frequencies several times during its early years, eventually finding a permanent home on 1380 kHz, sharing time on the frequency with religious broadcaster WAWZ in central New Jersey. It operated 18 hours a day with general entertainment and brokered programming. Since 2007, WKDM has broadcast in Mandarin Chinese 24 hours a day Monday through Friday, featuring drama, popular music, talk shows, news program, children’s programs and sports, as well as programs from China and Taiwan. The WBNX call sign is now used on UHF Channel 55 in Ohio.
