WWRU (1660 kHz) is a commercial AM radio station licensed to Jersey City, New Jersey, broadcasting to the New York metropolitan area. It airs Korean language talk and music shows, with the studios in Manhattan. WWRU broadcasts at 10,000 watts around the clock, using a directional antenna. With so few stations broadcasting on 1660 in the AM expanded band, at night, WWRU's signal can reportedly be heard as far south as the Washington metropolitan area and as far north as Southern Ontario. The transmitter is off Paterson Plank Road in Carlstadt, New Jersey. History WWRU originated as the expanded band "twin" of an existing station on the standard AM band. In 1979, a World Administrative Radio Conference (WARC-79) adopted "Radio Regulation No. 480", which stated that "In Region 2, the use of the band 1605-1705 kHz by stations of the broadcasting service shall be subject to a plan to be established by a regional administrative radio conference..." As a consequence, on June 8, 1988 an ITU-sponsored conference held at Rio de Janeiro, Brazil adopted provisions, effective July 1, 1990, to extend the upper end of the Region 2 AM broadcast band, by adding ten frequencies which spanned from 1610 kHz to 1700 kHz. The agreement provided for a standard transmitter power of 1 kilowatt, which could be increased to 10 kilowatts in cases where it did not result in undue interference. While the Federal Communications Commission (FCC) was still making U.S. preparations to populate the additional frequencies, known as the AM expanded band, a provision was added to the Communications Act of 1934 in late 1991 which mandated that priority for assignments would be given to existing daytime-only stations that were located in a community with a population over 100,000, and which also did not have any full-time stations. Taking advantage of this provision, on December 8, 1995 WJDM in Elizabeth, New Jersey, became the first station in the country to begin regular broadcasting on the expanded band, assigned to 1660 kHz. Initially, AM 1660 carried the same WJDM call letters as its parent station. On March 17, 1997 the FCC completed the process of determining which stations would be permitted to move to the expanded band frequencies, and WJDM was included among the eighty-eight selected, now formally authorized to move from 1530 to 1660 kHz. After more than two years of operation in the expanded band as WJDM, a
