Because 1580 AM is a Canadian clear channel frequency, WJFK must greatly reduce power at night to 270 watts, when radio waves travel farther.
[2] On November 12, 1953, former Federal Communications Commission (FCC), employee Harry Hayman received a construction permit for a radio station in Morningside operating at 250 watts daytime-only on 1580 kilohertz.
By then, the station played Top 40 hits with a format similar to WABC and WMCA in New York City and CKLW in Detroit.
Responding to the black population growth of the Washington area, WPGC began to alternate playing so-called "white" rock records with Motown and soul music hits.
After Max Richmond died in 1971, his estate received FCC approval on August 7, 1974, to sell the WPGC stations for $5.8 million to First Media Corporation.
First Media sold all of its properties for $177 million to Cook Inlet Radio Partners, a group of Alaska Natives, in early 1987.
"[7] CBS launched an online portal called "Connecting Vets" in June 2017, consisting of news and podcasts oriented toward military veterans.
Podcast content was combined with live drive-time news coverage into an Internet stream that also began airing on WJFK on June 5, 2017.
[10][11] (In March 2021, Entercom changed its name to Audacy, Inc.) Despite the move to a talk format, WJFK continued some local sports coverage as an overflow partner for WJFK-FM.
The station was nominally an affiliate of the Washington Nationals Radio Network, although coverage was limited to spring training games since WJFK-FM became the team's flagship.
[13][14][15] On April 9, 2018, WJFK flipped to a Spanish-language sports talk format as "El Zol Deportes", assuming the branding of its sister station WLZL (107.9 FM) and shifting its HD simulcast to WLZL-HD2.
