WGYM (1580 AM) is a radio station broadcasting a Spanish language format licensed to Hammonton, New Jersey, USA. The station is currently owned by Access.1 New Jersey License Company.[1]


The station went on the air as WNJH on May 11, 1961. It was originally owned by Harrell Trucking of Baltimore. In 1967 the station was purchased by Hammonton resident and local radio veteran Jim Rodio. By late 1971 the call letters had been changed to WRDI. Soon after Rodio launched FM station WRDR, which was simulcast with the AM station at times. Rodio sold the AM station and the call letters were changed to WTYO on December 31, 1981. WTYO played adult contemporary music and was affiliated with NBC. The station was eventually sold to The Green Group, based in Linwood, New Jersey. On March 25, 1991 the call letters were changed to WONZ and the station began to simulcast Pleasantville-licensed WOND. On March 22, 2001 the station assumed the WGYM call sign that had been used by The Green Group's station on 1400 AM in Pleasantville and began running the ESPN Radio programming that had been airing on 1400. On February 22, 2002, the station had dropped the ESPN programming and had gone back to simulcasting WOND.[2][3]

In the 2000s The Green Group's southern New Jersey stations were sold to Access.1 Communications Corporation. A subsequent resale of the radio group did not include WGYM; however, the owners of the ex-Green stations continued to provide programming to the Hammonton station.

In 2010, the station switched to a simulcast of WBSS.

As of August 12, 2011, WGYM was once again simulcasting WOND.

On March 19, 2014, WGYM split from its simulcast with WOND and switched to a Spanish language format.
