The 96.3 frequency debuted in 1975 as WRUM-FM from its former city of license, Rumford; the call letters were changed in 1981 to WWMR. In 1997, WWMR became WLOB-FM, and started simulcasting WLOB, which at that time broadcast a religious format. In 2000, WLOB and WLOB-FM were sold to Atlantic Coast Radio by Carter Broadcasting. The stations subsequently dropped their religious programming and picked up a news-talk format. In 2006, WLOB-FM relocated its transmitter from western Maine to South Paris to provide a clearer signal to the Portland area. Following the transmitter move, in 2008 WLOB-FM changed its city of license from Rumford to Gray. On August 25, 2008, WLOB-FM converted from the WLOB simulcast to a simulcast of The Big JAB.
From 1999 to 2008, The Big JAB's programming was also heard on 900 AM (WJJB, licensed to Brunswick; at that time). On April 25, 2008, that frequency (which became WWBK on March 18, 2008; the WJJB calls subsequently moved to 1440, previously WJAE) was sold to Bob Bittner (owner of WJIB and WJTO) for $27,000. Additionally, from 2000 to September 1, 2008, The Big JAB's programming was also heard on 95.5 FM (WJJB-FM, licensed to Topsham; initially, the station continued to broadcast under its previous WCLZ call letters); on that date, it began airing programming from Boston's WEEI in a simulcast with WPEI under the call letters WGEI.
