99.1 FM aired a religious format from its sign-on in 1965 to 1979 with the call letters KBBL ("K-Bible"). The original chief engineer, who signed KGGI on the air, was Lee McGowan. Upon its sale from C. Edwin Goad to Lyncoln and Sylvia Dellar in 1979, KBBL became KGGI. The original airstaff included program director Brian White, along with Bob West, Lisa Giles, Dan Harrison, Cliff Roberts, and Benny Martinez, while Jerry Clifton crafted the station's original format. When the acquisition closed, KGGI flipped to Top 40 (CHR)
