WCAU-TV Test Pattern
This is WCAU-TV's unique "news, time and music" test pattern. It was produced by a flying spot scanner. Adaptions for time and news made by the WCAU staff.
John G. Leitch, Chief Engineer for WCAU-TV, wrote in 1949: "...During the week of February 21st to 27th (1949) we telecast 57 hours of program exclusive of News-Test pattern operation. Twenty-six hours of this was of local origin and 16 and a half hours was live studio programs...."
What the test pattern (a clear and clean version) might have looked like on air!
