On weekdays, WJFK-FM has local personalities hosting sports shows in morning drive time, middays and afternoons.

WPRW-FM broadcast with an effective radiated power of 30,000 watts, but only using a 160-foot tower, so it was unable to cover the larger Washington radio market.

The transmitter was moved to Fairfax and the call letters changed to WEZR, airing 15-minute sweeps of beautiful music, mostly instrumental covers of popular songs, including Hollywood and Broadway showtunes.

Ultimately, the entire company renamed itself EZ Communications later in 1968, later going on to buy other stations nationwide and apply the format there.

[6] While WEZR and its sister stations remained successful into the 1980s, the easy format was seen as attracting older listeners, while most advertisers were seeking a younger demographic.

On October 3, 1988, the station flipped to an album-oriented rock format as WJFK, with the new call sign named after John F. Kennedy.

[16] Programs on the station during this era include Stern, Don and Mike,[17] Opie & Anthony, G. Gordon Liddy,[18] The Greaseman, Bill O'Reilly, Ron & Fez and the Sports Junkies.

[21] Howard Stern departed his terrestrial network of stations in 2005, including WJFK-FM, when he left for Sirius Satellite Radio.

WJFK-FM rebranded as "Free FM" in October 2005, as part of Infinity's plans for a nationwide hot talk network.

[27] For college sports, WJFK-FM became the Washington area home of Virginia Tech Hokies football and men's basketball.

[30][31] Immediately prior to the 2016-17 NHL season, WJFK controversially declined to renew its deal with the Capitals, with program director Chris Kinard stating he desired a more consistent sports-talk schedule in the evenings.

Since the Nationals and Washington Wizards took precedence on that station, any conflicting Capitals games were left with no home radio coverage at all, leading to complaints from fans and the media.
