CHNO-FM is a Canadian radio station broadcasting at 103.9 on the FM dial in Sudbury, Ontario. The station is branded on-air as Rewind 103.9 with a classic hits format.

The station began broadcasting on June 24, 1947 on AM 1440. It was a bilingual radio station, airing programming in both English and French, and was an affiliate of both CBC Radio's Dominion Network and Radio-Canada. It was operated by Sudbury Broadcasting, a company owned by F. Baxter Ricard and his wife Alma Ricard, and was the first bilingual radio station in Canada outside of Quebec. On November 9, 1954, CHNO moved to AM 900.

In 1957, Ricard opened CFBR on AM 550 as a full-time French-language station, and CHNO switched to full-time English. The licensing of CFBR, which took over the Radio-Canada affiliation from CHNO, made Sudbury Broadcasting the first commercial broadcaster in Canada licensed to operate two AM radio stations in the same city. On December 31, 1969, CFBR and CHNO swapped frequencies, CHNO moving to 550 and CFBR taking over the 900 slot. On May 14, 1976, the CRTC denied an application by Sudbury Broadcasting Co. Ltd. to change CHNO's frequency from 550 kHz to 570 kHz.

In 1980, Sudbury Broadcasting launched a new FM station CJMX. That same year, CHNO received approval to increase daytime power from 10,000 watts to 50,000 watts with the nighttime power to remain at 10,000 watts and would remain on 550 kHz. Also in 1980, Ricard also became a major shareholder in Mid-Canada Communications. Sudbury Broadcasting continued to operate independently, although it was eventually merged into Mid-Canada Radio in 1985. In 1990, Mid-Canada sold the stations to Pelmorex. Following this sale, CFBR adopted the new call letters CHYC.
