"Can you see me clearly?" Public TV image reception experiment (1939)

On May 13, 1939, to commemorate completion of the Broadcasting Hall in Uchisaiwai-cho, the first wireless TV signal in Japan was transmitted from STRL's 100-meter tower in Setagaya to the new Broadcasting Hall 13 km away. It operated according to the Japanese TV standard: a 441-scanning line, 25 frames/second, 4.5 MHz video frequency, 500 W output signal. Four TV sets installed in a backup broadcast equipment room on the 7th floor of the Broadcasting Hall displayed first a test pattern, then the experimental image.

In the STRL TV studio, using two iconoscope cameras, STRL employees would step in front of the cameras, taking turns saying: "Can you see me clearly? Can you see me clearly?" and announcing the station's call sign: "NHK Technical Research Laboratories experimental television station, J2PQ."
