In 1947, Rea purchased a half-interest in Port Alberni radio station CJAV. Several personalities who started there would move to CKNW. These included Joe Chesney, who became morning show host until moving on to establish Langley station CJJC (now CKST in Vancouver) in 1963, and Jim Robson, who would provide play-by-play for the newly-established Vancouver Canucks of the NHL beginning in 1970. On January 2, 1949, CKNW switched frequencies to 1320 AM and increased its power from 250 watts to 1,000. The station again increased power to 5,000 watts on November 5, 1954.
