Amateur TV, abbreviated "ATV", is full-motion TV transmitted and received over ham radio ("amateur radio"). W6VSV is the ham radio call sign of the owner of the station in those pictures, probably in the 1950's. Here in the San Francisco area of California, there are many of us who send and receive ATV signals, and even a relay station ("repeater") on the nearby Mount Diablo with the call sign W6CX. The stations do not use standard TV channels/frequencies; we use frequencies in the licensed ham radio bands instead, in the UHF range. The Mt. Diablo station W6CX has its signal on 427.25 MHz, which is in the 70cm amateur radio band but is also the same as USA cable-tv channel 58. People here can receive this station by putting their TV into "cable-ready" mode and selecting channel 58, but using an antenna rather than connecting the cable signal.
