WDIO TV Duluth, Minnesota

WDIO-DT (channel 10) in Duluth, Minnesota, and WIRT-DT (channel 13) in Hibbing, Minnesota, are television stations serving as the ABC affiliates for northeast Minnesota and northwest Wisconsin. The stations are owned by Hubbard Broadcasting. WDIO-DT's studios and transmitter facilities are located on Observation Road in Duluth.

WIRT-DT operates as a full-time satellite of WDIO; WIRT's transmitter is located at Maple Hill Park south of Hibbing. WIRT covers areas of Minnesota's Iron Range (including Grand Rapids, Virginia and Chisholm) that receive a marginal to non-existent over-the-air signal from WDIO, although there is significant overlap between the two stations' contours otherwise. WIRT is a straight simulcast of WDIO; on-air references to WIRT are limited to Federal Communications Commission (FCC)–mandated hourly station identifications during newscasts and other programming. Aside from the transmitter, WIRT does not maintain any physical presence locally in Hibbing.
