The station was launched September 29, 1947, as WNMP,[1] which had a light-classical and beautiful music format, along with broadcasting college sports on Saturday afternoons. State Representative Harry Semrow was one of the early owners. The station changed hands several times, and the call sign was changed to WLTD in the early 1970s.

On April 9, 1979, the station's call sign was changed to WONX.

On April 10, 2009, the previous WCGO on 1600, also owned by Kovas, went silent. On April 13, 2009, the call sign was changed to WCGO. With 1600 now vacant, WCGO on 1590 AM was able to increase daytime power to 10,000 Watts. Nighttime power is 2,500 watts using a four-tower directional antenna array.[2]

WCGO begun producing Talk Radio shows starting on September 2, 2014 including "The Franklin Raff Show" (weekdays 12 noon - 2pm) and "The Geoff Pinkus Show." On July 13, 2015 it moved legendary "Milt Rosenberg" to weekdays 4 p.m. to 6 p.m.

The current daily talk line-up also includes “Coffee & Markets” with Brad Jackson, “Modern Notion Daily” with Dara & Zack, and “The Federalist Radio Hour” with Ben Domenech.” The nationally syndicated “Coast to Coast AM" with George Noory airs from 12 a.m. to 5 a.m. every night.
