Owner: Infinity Broadcasting (Viacom)
Without any warning, WHFS signed Off the air at noon on January 12, 2005, replaced by Spanish-language "El Zol 99.1 FM." The station had recently been mired in a major ratings slump, giving Infinity Broadcasting impetus to flip the format. The format change was just one of the ramifications stemming from an earlier agreement between Infinity and Spanish Broadcasting System (SBS) that gave Infinity an equity interest in SBS.
On January 21, 2005, it was announced that WXYV (Live 105.7) Baltimore would resurrect WHFS on nights and weekends, broadcasting as "HFS on Live 105.7" with afternoon DJ Tim Virgin at the helm.
WHFS, whose call letters initially stood for "Hi Fidelity Stereo," started out in 1962 as the area's first stereo station. The station became freeform in 1968 under ownership of Hi Fidelity Broadcasters. Jake Einstein became part owner and GM in the early 70s. Originally on the 102 frequency based in Bethesda , the station went Off the air briefly in 1983 and resurfaced on the 99.1 frequency in Annapolis . Einstein sold the station to Duchossois Communications in 1988. Dennis Constantine was brought in as consultant and the station hired Tom Calderone as PD in 1990.
Calderone shifted the focus from freeform to a more current-based alternative, which was accelerated by PD Robert Benjamin in 1991. In 1993 ownership changed to Liberty Broadcasting and then SFX in 1996. CBS/Infinity acquired the station in 1997. The station went "jockless" in January 2002. On February 1 Graeme moved to mornings, replacing the Morning Crash. All the other air personalities returned to their regular shifts. Graeme, however, left in August 2002 and was replaced by the Sports Junkies from crosstown talk station WJFK the following October. Kathryn Lauren also left middays in the Summer of 2002. Lisa Worden became programming director in 2003, moving from the same position she held at KROQ in Los Angeles.
