UPDATE, NOVEMBER 18, 2019
Now we turn to the performance of over the air broadcasts. In the United States, the digital switch flipped in 2009. The below screenshots were captured today from OTA sources, converted to analogue with a digital converted box. The 66 year old restored Westinghouse H840CK15 does not tolerate commercials. When a bright white field appears, the set will bloom, lose focus and reset. During the program, the set is stable and performs fine. 51 days after restoration, the tuner has not drifted once, rock solid. My other three RCA color roundies from 1955, 1958 and 1963 all drift periodically. The faint grey vertical stripe visible on the center of the screen of movies I’ve posted, is not visible on broadcast television. I think it’s an rf problem. I bought an inexpensive Sony DVD player which requires an rf modulator. You can see the irregular silkscreen phosphor application and a purity problem in the lower right portion of the 15GP22. Mike tried his best to remove it.
These screenshots are from PBS, a 1966 Star Trek episode, season 1, episodes 11 and 13, local programming, a live episode of “Dancing With The Stars”, and a 1992 “Jonny Carson” show. Carson would retire from the show 3 months later.
