KYBG (102.1 FM) is a classic hits formatted radio station owned by Third Partner Broadcasting and serving the Lafayette and Lake Charles areas.
In 1994, 102.1 changed calls to KSIG-FM and became a simulcast of Adult Standards sister station 1450/KSIG, which lasted until April 10, 1997 when the signal was upgraded to 50 kW and entered the Lafayette market.
In 1998, KQIS had to drop the "KISS" branding (due to copyright infringement and a threatened lawsuit by Clear Channel).
The station was not sued and had to be renamed as Soft Rock 102.1, whilst sticking to the same Adult contemporary format.
Later that year, 102.1 was upgraded once more to 100 kW, extending coverage west to Lake Charles market and became a hybrid Adult Contemporary-Smooth Jazz "102.1 Kiss FM.
