However, for most of the time from the 1950s through the 1970s, it was one of only three stations in the state that was a member of National Educational Television (NET) and its successor, PBS.

The only other areas of the state outside of Milwaukee and Madison that had a clear signal from an NET/PBS member station were the northwest (from Duluth, Minnesota's WDSE-TV) and the southwest (from the Twin Cities' KTCA-TV).

During the late 60s and into the early 70s, commercial station KFIZ-TV in Fond du Lac was contracted by the UW-Madison Board of Regents to simulcast portions of WHA-TV's broadcast day, bringing WHA's programming into the Green Bay and Milwaukee markets.

The first was WPNE-TV in Green Bay in 1972, ending KFIZ-TV's part-time affiliation with WHA (and hastening its demise only two months after WPNE went on the air).

This was followed by WHWC-TV in Menomonie and WHLA-TV in La Crosse in 1973; WHRM-TV in Wausau in 1975 and WLEF in Park Falls in 1977, most taking call signs that originated from their co-owned radio counterparts.

From 1960 to 2007, WHA-TV/WPT aired same-day tape-delayed coverage of some Wisconsin Badgers football and men's basketball home games, which was produced in association with UW-Madison's athletic department.

All of the listed translators are owned by the WECB, and flash-cut from analog to digital in the first two weeks of November 2008, including adding the subchannel services.

In March 2021, PBS Wisconsin, by way of WHA-TV, was quietly added to Dish Network's Duluth–Superior local feed in standard definition.
