[GreenKeys] Hal ST-6 using it in modern times

[Richard Knoppow]

    405 line TV was used here experimentally in the 1930s. 
Commercial TV in the U.S. had a false start around 1940. Only a 
few stations got commercial licenses. It was then decided it was 
too early so the real starting date was the end of 1948. In Los 
Angeles there were two experimental stations that got commercial 
calls around 1940, W6XAO which became KTSL, later KNX-T now 
KCBS-TV and W6XYZ, which became KTLA. Both had fairly regular 
schedules until stopped by the war. There were other experimental 
stations, especially around the late 1920s but none survived.
