WMCA, 570 AM, is a radio station in New York City, most known for its "Good Guys" Top 40 era in the 1960s. It is currently owned by Salem Communications and plays a Christian radio format. Its three-tower transmitter site (easily visible from the northbound New Jersey Turnpike) is located on the Hackensack River, in Kearny, New Jersey. WMCA first went on the air on February 1, 1925, broadcasting from the McAlpin Hotel, from which its call letters derive. In 1928 it moved to the 570 kHz frequency. WMCA began playing rock music in the late 1950s with a Top 40 format. Among its disc jockey staff were future legends Scott Muni and Murray "the K" Kaufman.
