for an entertainment program promoting his family's La Palina cigars, bought the network with $500,000 of his family's money and renamed it the Columbia Broadcasting System. Actor Paul Douglas began his career at WCAU, where he worked as an announcer and sportscaster from 1928 to 1934. Power boost and shortwave In 1930, WCAU initiated a shortwave radio service, operating under the call sign W3XAU. It is believed that this was the first license issued by the FCC for a commercial international shortwave broadcast station. Initially W3XAU simulcast WCAU programming, but eventually original programming was created specifically for international listeners. W3XAU, later WCAI, then WCAB, was closed down in 1941 as CBS consolidated various shortwave operations. The 10 kW shortwave transmitter was disassembled, and WCAU staff were told that it was sent to England to aid the BBC war propaganda efforts. However, the transmitter was actually sent to Camp X, a secret World War II paramilitary and commando training facility located near Toronto, Ontario, Canada, becoming part of the Hydra signals intelligence and communications program. A series of power increases brought the station to 50,000 watts, with a new 50,000-watt transmitter dedicated October 2, 1932. The Levy brothers eventually became major stockholders in CBS, and were members of the network's board for many years. Studios and FM On December 26, 1932, WCAU moved to a new facility at 1622 Chestnut Street. Broadcasting (magazine) called it "a thoroughly modern 9-story building ... erected especially for the WCAU Broadcasting Co." The building included eight studios and "a special office for Leopold Stokowski, director of the Philadelphia Orchestra." WCAU began experimenting with an FM station in 1942 and it was licensed in 1943. The call sign in its early years was WCAU-FM and it broadcast at 102.9 MHz. CBS ownership The Levys agreed to sell WCAU-AM-FM to The Philadelphia Record in 1946. However, the Record folded shortly thereafter, and its "goodwill," including the rights to buy WCAU-AM-FM, passed to the Philadelphia Bulletin, which already owned WPEN and WPEN-FM, and had secured a construction permit for WPEN-TV (channel 10). In a complex deal, the Bulletin sold off WPEN and WCAU-FM, while changing WPEN-FM's call sign to WCAU-FM and WPEN-TV's call letters to WCAU-TV. The Levys continued to run the stations while serving as consultants to the Bulletin, and it was largely due to their influence that WCAU-TV took to the air on May 23, 1948,
