The station remained an NBC Blue Network affiliate through the network's selloff, becoming an [[American Broadcasting Company|ABC]] affiliate in 1945 when NBC Blue formally became ABC. The station kept the ABC affiliation until December 31, 1962.

WTCN began broadcasting from a new transmitter and tower in Roseville at the intersection of North Snelling Avenue and Minnesota Highway 36 during 1935, a site that was used until 1962 when the station's transmission facilities were moved to the other side of the expanding Twin Cities metro in St. Louis Park, at a point south of what is now Interstate 394 and west of Minnesota Highway 100, using four towers.  WTCN moved from 1250 AM to 1280 AM in March 1941 as required by the [[North American Regional Broadcasting Agreement]] (NARBA) under which most American, Canadian and Mexican AM radio stations changed frequencies.
