 The AM and FM sides began to air more separate programming as the 1970s went on, with 960 AM continuing in its Top 40 format while 104.9 FM became a country outlet, changing its call letters on November 1, 1980 to KASC, for "Acadiana/Stereo Country".In 1984, KROF became known as "Boss 96".Two years later, however, 104.9 became KROF-FM and the two stations resumed a simulcast of what had been the FM's country format.
