WOKI airs ABC Radio Network's "True Oldies Channel" syndicated format as of August 10, 2007, at 10:00 AM EDT, switching from its locally-programmed Adult Hits/variety format known as "Earl-FM." WOKI operates a 8,000 watt tower at 98.7 MHZ twenty miles northwest of Knoxville, TN. Its city of license is Oliver Springs, Tennessee.
Meanwhile, WOKI-AM broadcasted on 1550 kHz on the AM dial with an adult contemporary format. WOKI-AM became WORI and eventually ceased broadcasting altogether, while WOKI-FM after its switch to the Top-40 format was in heavy competition with WRJZ (620 AM), and later WIMZ (103.5 FM) for the Knoxville market's top rock station.
After the early 1980s WOKI dropped the hard and southern rock and sports, and became strictly a Top-40 pop station thru 1993, broadcasting as "FM 100", "Hits 100", and "I-100". The station became known as "The Hitkicker," in 1993 broadcasting a country format until 1998 when they chaged to an Adult Album Alternative format as "100.3 The River" and later, "98.7 The River" and "98.7 Earl-FM" when the WOKI call letters moved to 98.7. The 100.3 frequency is now occupied by WNOX with a talk radio format.
WOKI's tower while on 100.3 was on Cross Mountain north of Briceville, Tennessee and their signal could be received throughout east Tennessee as well as significant parts of southeastern Kentucky, and in small portions of Virginia, North Carolina, West Virginia and Georgia.
NOTE: The station still uses the former 987earlfm.com web address.
