WDCG (105.1 FM) is a commercial Top 40 (CHR) station licensed to Durham, North Carolina and serving the Raleigh-Durham radio market. Its studios are located on Smoketree Court in Raleigh's Highwoods Office Park and owned by iHeartMedia, along with WNCB, W237BZ, WRDU, and WTKK. The transmitter site for the station is in Apex. WDCG broadcasts in the HD Radio format. History WDCG first began as a radio station on February 29, 1948 as WDNC-FM 105.1, a sister station to WDNC; both were owned by Durham Morning Herald and The Durham Sun. The sign-on of the 36,000-watt FM station coincided with the AM station's power increase and frequency shift from 1490 to 620 kilohertz. In 1953, the Herald-Sun group joined WTIK owners Floyd Fletcher and Harmon Duncan in securing a license to operate a television station in Durham, which would eventually become WTVD Channel 11 the following year. Until the mid-1970s, WDNC-FM simulcast the AM programming from an antenna located atop one of AM 620's three towers on Shocoree Drive in western Durham just off Interstate 85. (The old 105.1 FM antenna was visible on the easternmost tower until the site was razed in late 2017.) In 1974, WDNC-FM became a country station and changed its calls to WDCG-FM (Durham's Country Giant). The station later switched to rock music in the late 1970s before becoming a Top 40 station in Fall 1981. A year later, the station boosted their power to 100,000 watts and moved to the former WRDU-TV (now WRDC) tower at Terrell's Mountain in northern Chatham County. This allowed WDCG-FM to put a city grade into Raleigh, Durham and Chapel Hill, as well as a 60 dbu signal into Greensboro-High Point-Winston-Salem, where the station even beat the local Top 40s from 60 miles away. WDCG, licensed to Durham, was the first station in the Raleigh-Durham market to obtain a dual city of license in terms of their station identification in 1982, and surprised the stations in Raleigh with its designation of "WDCG-Durham, Raleigh, Chapel Hill." With no promotional dollars and against the powerhouses of WRAL-FM and WQDR-FM, WDCG grew every six months in Arbitron starting in the Fall of 1981 with a 1.8 - 4.5 - 9.0 - 9.8 - 11.1 - 14.5 by the Spring of 1984. WDCG was operated as a loss leader for years by the Durham Herald-Sun, as the owners felt eventually newspapers would be
