Lite Rock 102 tried several different experiments to boost ratings, including jazz in the afterhours and oldies on the weekends, but none brought it much success.
On January 2, 1991, at 9:00 p.m., during Jamie Lee's airshift, the station announced it was changing call letters to KOQL and would become known as "Kool 102".
The oldies format was fairly successful, but Entercom announced just before Thanksgiving 1993 that KOQL would be the first station it would sell in roughly 20 years.
Newmarket Communications, owner of country KXXY 1340/96.1, would purchase the station and begin operating it immediately in an LMA.
The call letters changed to KTST on March 11, 1994 when the FCC approved of the license transfer from Entercom to Newmarket.
The result was a bigger cluster at 50 Penn Place, including KTOK 1000, KXXY 1340/96.1, KJYO 102.7, KEBC 94.7 and KTST 101.9.
Worked for KTNT 97.7/97.9 during its jazz and smooth Jack Elliott and Ron Williams - Morning show on K-Lite 102 and KOOL 102.
