WNYM

In November 1926 WAAT introduced broadcasts originating from the Hotel Plaza in Jersey City.[14]

Bremer returned to the broadcasting airwaves four years later, with a new station licensed on August 19, 1926 to the Bremer Broadcasting Corporation in Jersey City, which was assigned the sequentially issued call letters WKBD.[15] WKBD began a series of test transmissions in late August, initially broadcasting from Bremer's store at 210 Jackson Avenue.[13] The next month Bremer was permitted to reclaim the call sign used in 1922,[16] and the station was renamed WAAT.[17] Its initial slogan was "The Voice At the Gate of the Golden State".[18] A formal debut broadcast from studios at the Hotel Plaza in Jersey City was held on November 20, 1926.[19]

WAAT began operations during a chaotic period when most government regulation had been suspended, and new stations were free to be set up with few restrictions, and could chose their own transmitting frequencies. Bremer initially squeezed WAAT onto the crowded New York area AM band using a non-standard frequency of 1275 kHz. Following the reestablishment of government control by the formation of the Federal Radio Commission, on May 3, 1927 the station was moved to a more traditional frequency of 1270 kHz,[20] which a month later was changed to 1220 kHz.[21] In November 1928, the station moved to 1070 kHz,[22] which was followed by a switch to 940 kHz in April 1930.[23] Effective March 1941, under the provisions of the North American Regional Broadcasting Agreement, stations on 940 kHz were reassigned to 970 kHz, which has been the station's frequency ever since. In 1943, WAAT's main studio location was changed from Jersey City to Newark, New Jersey in the Hotel Douglas, later moving to the Mosque Theatre at 1020 Broad Street.

In 1947 Bremer launched an FM adjunct, WAAT-FM (94.7, now WNSH), and the following year a sister television station, WATV, began broadcasts on channel 13. In 1951 the stations were sold to Irving Rosenhaus; WAAT evolved to a middle of the road music format by the 1950s, similar to what WNEW, WOR, and WCBS were doing at that time.

In 1957 the WAAT/WATV operation was sold by Bremer to National Telefilm Associates, who changed the station's call letters to WNTA.[24][25] National Telefilm split up its holdings in 1961, with WNTA-TV (now WNET) being sold to a New York City-based nonprofit educational group, and the WNTA radio stations going to Communications Industries Broadcasting.[26] The new owners changed the calls to WJRZ[27] and retained the MOR format until September 15, 1965, when WJRZ became the first radio station in the New York metro area to play a country music format 24 hours a day.[28] It was also the flagship radio outlet for the New York Mets from 1967 until 1971.

In 1968 the station established a new transmitter site in Hackensack, New Jersey, and changed its community of license from Newark to Hackensack. A serious fire destroyed its studios located in a house on Hackensack Avenue in North Hackensack on October 17, 1970; the station operated out of a prefab building near their transmitter site for a period of time afterward.

The station was put up for sale in the fall of 1970. Around that time, future sister station WMCA dropped top 40 for a talk format, leaving WABC as the only Top 40 radio station.

WJRZ was sold to Pacific and Southern Broadcasting (which merged with Combined Communications Corporation in 1974) on January 6, 1971[29] and the call letters were changed on May 16 of that year to WWDJ (known on the air as "97-DJ"), and the station attempted to take on WABC and replace WMCA as the New York market's second Top 40 outlet. For a brief time, program director Mark Driscoll began imaging the station as "9-J", giving rise to a recorded parody of the station called "Nine" produced by a group that included disk jockeys Howard Hoffman, Randy West, Pete Salant and Russ "Famous Amos" DiBello.[30]

The station was hampered by a directional signal that covered Manhattan and parts of New Jersey well but suffered in the rest of the Five Boroughs and was virtually nonexistent on Long Island and western New Jersey. Eventually, FM competition from WCBS-FM and adult top 40 station WXLO (now WEPN-FM), and an evolution to adult Top 40 by WNBC (now WFAN), began to eat into WWDJ's ratings. In November 1973 it was ranked 15th in the Arbitron ratings.

By 1974, the station was losing money and unable to sell enough advertising. The studios were moved to the transmitter site. In the fall of 1973, the station began selling airtime to religious groups on weekends, which brought much-needed revenue for the station as it continued with Top 40 during weekdays into 1974. But as a result of the religious hours making money, WWDJ abruptly dropped the top 40 format on April 1, 1974, and switched to a religious format full time. Because the change took place on April Fool's Day, many listeners thought the switch was some sort of joke. Initially, WWDJ sold two-thirds of its daily airtime to outside ministries and played traditional Christian music the rest of the time, with the exception of a few hours on Saturdays devoted to a then-new genre, contemporary Christian music. WWDJ was sold to Communicom Corporation of America in April 1978,[31] about a year before Combined Communications' merger into the Gannett Company in 1979.

By the late 1976 the music during the week was a mix of traditional and soft contemporary. By 1979, the music was adult contemporary Christian and evolved to contemporary Christian by 1982. The station still only played music part-time on weekdays and Saturdays. They continued with the contemporary Christian music/teaching/preaching format throughout the 1980s and into the 1990s, with Frank Reed (formerly of WNBC) handling mornings.

In 1994 WWDJ was sold to Salem Communications,[32] which since 1989 has owned WMCA, initially retaining its studios on Main Street in Hackensack. As WMCA ran Christian talk and teaching, it was thought that WWDJ would move to music full-time with specialty Christian music programming on weekends. While this did not happen, WWDJ by the end of 1994 was playing music.

In the fall of 1995, the station abruptly changed formats. The station's teaching programming expanded, with music cut back to morning and afternoon drive time hours on weekdays and Saturdays afternoons. Most of the announcers were laid off and the station revamped the format to a rhythmic Christian music format. This employed contemporary worship music, gospel music and light contemporary Christian songs. They positioned themselves as "The Sound of Praise and Celebration". George Flores was the only air-staffer retained and his afternoon show was pre-recorded. In 2002, local on-air personalities expanded Sylvia Lynn Pate and "Transitions with Sylvia Lynn" which was added to their weekday evening line-up. Sylvia was WWDJ's first African-American female official on-air talent.

This format continued until 2004, when the music was dropped and WWDJ moved to a Christian brokered format. Around this time, Pillar of Fire Church-owned WAWZ (99.1 FM) in Zarephath dropped all but a few religious programs to play contemporary Christian music 18 hours a day, and Salem picked up many of the bumped shows; this caused Salem to decide to air programming full-time on WWDJ. For about two years, the station billed itself "WMCA II" all the time, with the WWDJ call letters used only in the hourly station identification. The station's on-air identity reverted to "970 DJ" by 2007, but programming continued to be overflow programs from WMCA, as well as some syndicated mostly-secular personalities such as Laura Schlessinger and Kevin McCullough. They also broadcast infomercials and church services, as well as 30- and 60-minute religious shows.

On July 25, 2008, WWDJ swapped call signs with a sister station in the Boston area and briefly became WTTT. It stunted for several days with all-Frank Sinatra ("Frank 97 AM") programming, followed by a short stint of all-Pat Boone ("The Booner 970") music.[33] On August 6, 2008 the station's call letters were changed to WNYM, a transfer of the call sign Salem had used on AM 1330 (now WWRV) since 1981. This change included adopting a conservative talk format[34] and Fox News affiliation.

John R. Gambling hosted a midday show on WNYM from April 2014 until September 2016. The station shared New York City radio rights to the NHL's New York Islanders with Entercom-owned WFAN-AM-FM during the 2016-17 and 2017-18 seasons. The Islanders' broadcasts were produced by the team's flagship radio outlet, Hofstra University-owned WRHU in Hempstead.[35] Beginning in 2018-19, Islanders radio coverage outside of Long Island is available exclusively through streaming, through Entercom-owned Radio.com and on the Islanders' and WRHU websites.
