Looks like it was channel 18. They moved to 24 in 1994. I vaguely recall games on channel 4 but that was when they showed like 10 a year. Five of the six major network television stations in Milwaukee, along with WMLW-CA, have carried game broadcasts over the years, with WTMJ-TV being the original broadcaster in the 1970s. WVTV carried the team for the bulk of the 1980s and early 1990s, with WCGV-TV following from 1994 until 2004, and WISN-TV carrying select Sunday games at the beginning of the 2000s.
