[1] WKSI-FM is owned and operated by iHeartMedia[4] 98.3 FM signed on August 28, 1967, as WZFM, a local station serving Charles Town, West Virginia.

The station was co-owned with WXVA (1550 AM) by Arthur W. Arundel, who at the time owned WAVA Arlington and the Leesburg-based Loudoun Times-Mirror newspaper.

WZFM simulcast WXVA's broadcasting day, which was Full Service with blocks of country music.

After an initial return to simulcasting 1550 AM (which had flipped to middle-of-the-road) immediately after the change, the station settled on light adult contemporary around 1986.

[10] The station remained in Charles Town, but was a rimshot to Winchester, regularly showing up in the ratings there despite competition from local country stalwart WUSQ-FM.
