4, while the reallocation provisions had reserved 1020 kHz for use in Region 2, a grouping of mid-Atlantic states. Westinghouse fought a long legal battle, attempting to keep KYW operating as a clear channel station on 1020 in Chicago. Finally it proposed moving the station to a Region 2 location, settling on Philadelphia. However, numerous other stations made alternative proposals to be assigned this allocation, and the matter was placed in the hands of an FRC examiner, who held hearings in July 1932 to sort through 23 conflicting applications from 16 stations. Examiner Pratt's recommendation concluded that KYW's willingness to move to Philadelphia was the best possible outcome. After broadcasting its last program in Chicago on December 2, 1934, KYW aired its debut Philadelphia program the next day. Westinghouse used the studios and sales operations of WCAU. The move made KYW the easternmost U.S. radio station with a call sign beginning with "K". When KYW moved to Philadelphia, it changed from NBC Blue to NBC Red, predecessor of modern-day NBC, an affiliation it maintained during the remainder of the 1930s and throughout the 1940s; KYW was thus unaffected when, in 1942, the Federal Communications Commission (FCC) compelled RCA to divest itself of one of its two radio networks, resulting in the divestiture of the NBC Blue network (which later became the American Broadcasting Company). In mid-May 1938, KYW moved to new studios at 1619 Walnut Street in Center City. On March 29, 1941, KYW's clear channel assignment was shifted from 1020 to 1060 kHz, its current frequency, as part of a nationwide adjustment of assignments engineered by the North American Regional Broadcasting Agreement (NARBA). In 1942, KYW added an FM station at 45.7 megacycles, W57PH. It largely simulcast KYW's programming and later moved to 92.5 MHz as KYW-FM when the FM dial was shifted. But development of FM radio was slow and Westinghouse decided to shut down KYW-FM in mid-1954; the equipment was donated to the Delaware Valley Educational Television Corporation and the Philadelphia Board of Education. KYW acquired a television counterpart in late February 1953, when Westinghouse bought WPTZ (channel 3), the nation's third commercial television station and NBC's second television affiliate, from Philco. KYW Cleveland/WRCV Philadelphia (1956–1965) In June 1955 Westinghouse agreed to trade KYW and WPTZ to NBC in exchange for NBC's Cleveland properties, WTAM-AM-FM and WNBK television; Westinghouse also received $3 million in cash compensation.
