 KAVS and KYHT dropped their modern rock programming and began simulcasting the top 40 format of sister station KIIS-FM (102.7 FM) in Los Angeles part-time as "97.7 & 105.3 KIIS-FM".In the early days of Jacor/Clear Channel ownership, KYHT/KAVS featured local programming hosted by Chester The Arrester and held many on-air events in the Antelope Valley and Barstow areas.In early 1999, KYHT went off the air due to a windstorm that caused the transmitter building to buckle and become airborne; the station returned to the air after three days.
