[5] The simulcast ended in late 1977 when WSPT (AM) flipped to country music as WXYQ; the FM outlet retained the top 40 format and adjusted its call sign to WSPT.
In October 1993, the station switched to an adult contemporary (AC) format, branding itself as "Sunny 98".
By the middle of the decade, this was adjusted to a modern AC presentation as "Today's Music Revolution, 98 WSPT"; in 1996, the station changed its call sign back to WSPT-FM.
In 2005, the station flipped to ABC Radio's fledging syndicated adult hits format, "Jack FM", reverting to the "97.9 WSPT" branding when it flipped to oldies featuring programming from The True Oldies Channel.
Syndicated programming on WSPT includes America's Greatest Hits, a weekly show hosted by Scott Shannon.
