New York City' Rockefeller Center for television use. The transmitter was installed in one of the upper floors of the Empire State Building, with the antenna on the mooring mast, 1285 feet above street level. Two links interconnected the studio and transmitter. One of these was an underground coaxial cable approximately a mile in length, the other was a radio link. Video carrier frequency was 46.5 mHz and aural carrier was 49.75 mHz.
On June 29, 1936, NBC began field-test television transmissions from W2XF/W2XK to an audience of some 75 receivers in the homes of high-level RCA staff, and a dozen or so sets in a closed circuit viewing room in 52nd-floor offices of the RCA Building. The viewing room often hosted visiting organizations or corporate guests, who saw a live program produced in the studios many floors below. Eventually these transmissions were received on about 200 experimental receivers scattered throughout the New York area.

The first made by RCA and the National Broadcasting Company for the press under practical working conditions, although previous demonstrations of laboratory television have been given. It represented the first showing of a complete program built for entertainment value as well as a demonstration of transmission.
In 1936 only three receiving sets were located in NYC at the time of this demonstration which was mostly a closed circuit affair, but was broadcast by NBC/RCA's W2XBS in NYC. This broadcast originated from NBC's first television studio which was 3H and was seen by a group of NBC radio affiliate executives on the 62nd floor of the Rockefeller Plaza headquarters in hopes of interesting them in being television affiliates as well. This is not a Kinescope of the broadcast but is a Pathe newsreel film of the event shot in the studio.
