On January 24, 2011, WQJQ relaunched as "Oldies 105.1" and in the process changed its call letters to WJDX-FM. The original WJDX-FM call letters were on a progressive rock station at 102.9 (now WMSI-FM) from the late 1960s through the early 1970s. The station changed its calls to WZZQ in 1973 and would evolve from progressive rock to a locally produced AOR music format.
WJDX's oldies format includes some of the songs that were popular on WJDX-AM when that station played Top 40 music during the 1970s.
In November 2013, WJDX flipped to its usual Christmas music format for the holidays. However, it changed its name to "FM 105.1: The Christmas Station," possibly meaning a change coming after the holidays. On December 26, 2013 WJDX-FM rebranded as "The River".
