I need the help of the Wisconsinites. I recently stumbled across some ads for early color sets in Escanaba, Michigan circa 1956 and 1957. Anybody from Michigan, or Wisconsin for that matter, knows that Michigan's Upper Penninsula was, and is, pretty desolate. The only television station in the UP that would have been broadcasting at that time, WDMJ in Marquette, was a strictly monochrome affair.
That leaves only the north-eastern Wisconsin stations in range of Escanaba, and even then, only in the deep fringe at about 100 miles. I can't find any references to a station in the Green Bay or Marinette areas broadcasting in color. I briefly considered that they may have been picking up Milwaukee, but reception at 192 miles seems unlikely to me.
Any ideas?
