History
Early years
The station was first licensed to the Ocean City Yacht Club as WIAD in
Ocean City, New Jersey, and
signed on the air in July 1922. The station was originally assigned to the "entertainment wavelength" of 360 meters (833 kHz), and call letters were randomly assigned from a sequential roster of available call signs. In 1923, ownership was transferred to Howard R. Miller, who moved the station to Philadelphia.
Following the establishment of the
Federal Radio Commission
The Federal Radio Commission (FRC) was a government agency that regulated United States radio communication from its creation in 1927 until 1934, when it was succeeded by the Federal Communications Commission (FCC). The FRC was established by ...
(FRC), stations were initially issued a series of temporary authorizations starting on May 3, 1927. In addition, they were informed that if they wanted to continue operating, they needed to file a formal license application by January 15, 1928, as the first step in determining whether they met the new "public interest, convenience, or necessity" standard. On May 25, 1928, the FRC issued
General Order 32, which notified 164 stations, including WIAD, that "From an examination of your application for future license it does not find that public interest, convenience, or necessity would be served by granting it."

''Second Annual Report of the Federal Radio Commission for the Year Ended June 30, 1928, Together With Supplemental Report for the Period From July 1, 1928 to September 30, 1928'', pages 146-149. However, the station successfully convinced the commission that it should remain licensed.
On November 11, 1928, the FRC made a major reallocation of station transmitting frequencies, as part of a reorganization resulting from its implementation of
General Order 40. WIAD was assigned to 1370 kHz.
In 1929, the station's studio and transmitter were moved to the
Elks Club at Broad and Vine Streets and the
