The station was eventually licensed to broadcast with a transmitter power output (TPO) of 5,000 watts, the maximum at the time allowed for stations operating on a "regional" frequency. In 1946,
The Newark Sunday Call purchased WBYN, through its subsidiary, North Jersey Radio. At the time,
The Newark Sunday Call was being purchased by the
Newark Evening News. In 1947, the call sign was changed to WNJR and the
community of license was changed to Newark. The station diversified its programming, running jazz blocks,
R&B music, talk shows, and Latin music. In 1953, Rollins Broadcasting bought the station. As Newark's population became increasingly African-American in the 1960s, WNJR evolved into an R&B music format full-time. Some of the jockeys included Hal Wade,
Danny Stiles, Bobby Jay, and Hal Jackson. In 1967, Rollins Broadcasting, after a dispute with its air staff, restructured into Continental Broadcasting. During the 1950s and 1960s the station featured some of the earliest
rock and roll programming in the New York area, including the first claim to airing
Alan Freed in that region. Despite being licensed to Newark, from the late 1950s through the 1970s the station broadcast from a studio in
Union. The station's two guyed broadcast towers were well known to residents of the newly developed College Estates section of Union. WNJR suffered from poor nighttime signal coverage due to its FCC-mandated directional antenna signal pattern. Additionally the station's antenna system's capacity hat design radiated too much signal skyward and not enough toward the ground where listeners reside. This caused signal cancellation and fading. Co-channel interference also limited its nighttime coverage ..
License revocation In 1968 the FCC denied Continental Broadcasting's license renewal, after finding that the former manager, Leonard Mireison, had committed "gross mismanagement and fraud on the commission", although it was allowed to continue to run the station, which was profitable, while this decision was being appealed. The soul format continued as well. As Newark became predominantly African-American during the 1970s, WNJR switched to a black-oriented music and news format.
Interim Operation assignments In July 1971 WNJR's license was officially revoked and the station went off the air on July 21. It signed back on a week later, still as WNJR, after the FCC authorized the City of Newark to run the station under an Interim Operation authorization. However, the next year the city informed the FCC that it could no longer afford to run the station, and a new Interim Operation authorization, again still as WNJR, was assigned to a three-member consortium operating as the WNJR Radio Company. WNJR continued with an urban contemporary format and became the flagship station of Unity Broadcasting's
National Black Network (now Sheridan Broadcasting's
American Urban Radio Networks) in 1973. WNJR evolved into more of an urban adult contemporary (AC) format by 1978. Also, the station played gospel music and sermons on Sunday mornings and evenings. While WNJR was being run under Interim Operation authorizations, the FCC held hearings to determine a new permanent licensee, and in 1977 Sound Radio received the grant for the WNJR replacement. Under the new owners the WNJR call sign was retained and the format stayed much the same. Initially the station was profitable, but by 1988 it began to lose money as its core audience switched to New York City's two FM urban powerhouses,
WBLS and
WRKS (98.7 Kiss FM). In 1989, Sound Radio filed for Chapter 7 bankruptcy.
Brokered format In 1991 American Radio Associates bought the station and attempted to keep the urban AC format, but also had financial problems, and sold the station to Douglas Broadcasting in 1992. At that point the station dropped its urban AC format in favor of gospel music mornings and late afternoons, ethnic brokered shows mid-days and nights, and gospel music and teaching on Sundays. In 1995,
Multicultural Broadcasting bought the station and shifted its programming to include more Asian shows. They kept some gospel music programming on Sundays. The station was then profitable. ==WNSW==
