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. These screenshots are compressed. For full resolution 6000 X 4000, go here: https://visions4netjournal.com/westi...r-tv-part-two/

My experience with modern TV commercials on this set is the same, too much white and the picture goes dim and out of focus. Turn down the brightness to make up for it and normal pictures are way too dim. I have a Motorola color set made in 1967 that does a bit better in the same situation but will still show vertical bending in the picture if there is black and bright white sections on top of one another. I guess these commercials were made for modern tastes and TVs.
Still, I find the video quality and detail are at least equal to, if not better than the majority of vacuum tube color sets which came after. The only downsides were the finicky and imperfect convergence and the unavoidable pincushion distortion due to the flat faceplate.

Do we know when the Macy's Parade was first shown in color?

New York Times tv column has it in 1960. Photo is not exact date. Just for camera fans.

UPDATE, DECEMBER 8, 2019
Having fun with our recently restored Westy. I admit we were skeptical on the outcome. This video, displays a short clip from a live broadcast, 6 PM (MST) of the 2019 Ms. Universe pageant on December 8, 2019. The program is very good source material for color reproduction demonstrations and the signal was received from an analog rooftop antenna, just as it would have used in 1954. The television being a 66 year old Westinghouse H840CK15 color model, is reported to be the *first production color set in the world, using an RCA engineered 15GP22 CRT, which was also the first production color tube. *See the Admiral CK1617A page. https://visions4netjournal.com/admiral-c1617a-color-tv/ Video: https://videopress.com/v/2n3WI7zD High resolution screenshots from the above same broadcast. https://visions4netjournal.com/wp-co...iverse-add.pdf

Thank you. All credit to Mike.
Please excuse me if I’m overstaying my welcome with these screenshots. I can’t resist showing what a 66 year old set is capable of. Last night, I was flipping through the channels and saw the opportunity of these two shots. The first, blown up from ‘Hogan’s Hero’s’. At first I thought she was Barbara Bain, not sure now. CBS film, good detail. The second, from original’Star Trek’ series. I always thought the show had nice color, depth etc. NBC, softer Technicolor look. https://visions4netjournal.com/wp-co...557EFFB89E.png https://visions4netjournal.com/wp-co...27888088C2.png
