York City performers – who were not paid – to make the trek to Newark, so on February 5, 1922, a more convenient remote studio was opened at the Waldorf-Astoria, located on Fifth Avenue and 34th Street. The American Telephone & Telegraph Company (AT&T) was unwilling to provide a telephone line to connect the Waldorf-Astoria studio to the Newark transmitter, so the link was instead made using specially prepared telegraph wires provided by Western Union. However, this expedient only provided marginal audio quality, and "the line was so noisy that when Newcomb Carleton, the president of Western Union, broadcast over it, his voice was completely drowned out". On March 15, 1922, WJZ broadcast a studio performance of Mozart's Impresario, probably the first full-length opera broadcast in the New York City area. In October 1922, the station aired its second World Series, this time also feeding it to WGY in Schenectady, New York. Shortly after midnight on December 9, 1922, WJZ became the first broadcasting station confirmed to have been heard in Europe, consisting of a short program featuring greetings from the British consul in New York to British listeners and Vaughn De Leath singing her "Oliver Twist" song. WJZ New York City (1923–1953) Takeover by RCA May 15, 1923, saw a number of simultaneous major changes. Most notably, on this day the station moved from Newark to New York City, and the ownership was changed from joint Westinghouse-RCA responsibility to full control by RCA. WJZ moved to studios on the sixth floor of the building where the Aeolian Hall was located, and station publicity heralded the upgrade: "Located in the heart of the city's musical and theatrical district, where entertainment of the highest order is ever available, this station will offer to the American public the most elaborate radio programs yet attempted and with a degree of faithfulness in reproduction that marks the beginning of a new era in radio broadcasting." This was also the day that the Department of Commerce implemented an expansion of the broadcast band, which now consisted of a range of transmitting frequencies from 550 to 1350, with WJZ assigned the sole use of 660. Finally, a sister station with the call letters of WJY operating on 740, was established, which shared the "Broadcast Central" Aeolian Hall studios, with WJZ providing more serious programming, and WJY's offerings considered more informal.
