WOLL

In 1971, the station signed on in Riviera Beach, Florida, as WGMW, owned by WGMW, Incorporated, and airing a Top 40 music format.[3] It was powered at 3,000 watts on a 300-foot antenna, as a Class A FM station with coverage limited to the communities around Riviera Beach and West Palm Beach.

In 1978, the station was bought by the Pearl Broadcasting Company.[4] The new owner switched the call letters to WNJY to represent the word "Enjoy." It maintained its easy listening sound for several more years.

In 1982, the station was bought by Lappin Communications, which changed the call sign to WMXQ, calling the station "Mix," and installing an adult contemporary music format.[5]

In 1988, the station flipped to an oldies format, changing the call letters to WOLL, representing the new moniker "Oldies 94.3." Original air personalities were Steve Cody, Skip Kelly, Donnie Pachine, Steve Street, Rock-n-Roll Joel, Patti Stevens, Barry West, Lorna O'Connell, and Lindy Rome.

In 1993, J.J. Duling was hired as Program Director, with the DJ staff made up of Duling, ex-CKLW personality Art Riley and Lorna O'Connell in mornings, along with Mike Casey, Dave Brewster and Rock-n-Roll Joel.

In 1998, WOLL was acquired by Clear Channel Communications, the forerunner to current owner iHeartMedia. To increase its coverage area, the station changed frequencies from 94.3 MHz to 105.5 MHz, still playing oldies, but now calling itself "Kool 105.5." The city of license was switched to Hobe Sound, an unincorporated community in Martin County, Florida, about 25 miles north of West Palm Beach. The power was increased to 50,000 watts from the previous 3,000 watts. The new signal could be heard from Boca Raton to Palm City. The DJ line-up consisted of Skip Kelly, Mike Perry, Joe Steel, Russ Riba, and Rock-n-Roll Joel. The 94.3 frequency was replaced by a new station, also owned by Clear Channel, WWLV (now WRLX). WWLV aired a Smooth Jazz format as "Love 94."[6]

In 2002 and for the next several years, Kool 105.5 would play all Christmas music between the day after Thanksgiving and New Year's Day. The following year, the Mo & Sally Morning Show joined KOOL 105.5 from AM 1230 WJNO (now at AM 1290). They were previously on 97.9 WRMF and 102.3 WMBX.

In 2005, Tim Allan Walker joined The Mo & Sally Morning Show from 1290 WJNO/Air America Radio. KOOL 105.5 broadcast a week of Hurricane Wilma recovery information spearheaded by The Mo & Sally Morning Show with Tim Allan. The station was recognized for its disaster recovery efforts.

In 2007, Kool 105.5 and the other West Palm Beach stations owned by Clear Channel Communications became news partners with NBC network affiliate WPTV-TV 5. It discontinued its arrangement with CBS affiliate WPEC-TV 12. Clear Channel also changed newspaper partnerships from the Palm Beach Post to the Sun Sentinel. Mike Perry exited the station for an afternoon drive gig in New York at Fresh 102.7 WNEW-FM. Tim Byrd joined the station in afternoons. Bobby Rich exited and headed back to Tampa. Jennifer Agostino was named Program Director for WOLL (she was also the Program Director for 92.1 WRLX) but later exited. Skip Kelly returned to take over midday duties.

Jennifer Agostino left WOLL in October. Jodi Stewart took the reins as Program Director. The syndicated John Tesh program was added to the line-up from 7 pm to Midnight, six days a week, when his original West Palm Beach affiliate, 92.1 WRLX, flipped to Spanish Contemporary from Soft AC. (Tesh was later replaced by another evening show hosted by Mario Lopez and syndicated by Premiere Networks, a subsidiary of parent company iHeartMedia.)

In 2008, WOLL returned to its partnership with the Palm Beach Post, discontinuing the arrangement with the Sun Sentinel. On January 25, 2008, Clear Channel announced that WOLL would be one of a number of its radio stations to be sold, in order to remain under Federal Communications Commission ownership caps following the sale of Clear Channel to private investors. Until the sale, WOLL and the other stations were placed into the Aloha Stations Trust.[7][8] In December 2008, Clear Channel took back WOLL after Arbitron reassigned its sister stations, WLDI in Fort Pierce and WMAX-FM in Holland, Michigan, to new markets.

In 2009, Tim Byrd exited, Skip Kelly moved to afternoons and Mike Perry returned to middays.

On January 1, 2010 WOLL changed its format to an 80s/90s/2000s-based adult contemporary sound, still under the "Kool 105.5" branding. In June Of 2016 T.A Walker left Kool 105.5 to return to his hometown of Austin, Texas.
