Until June 2010, "Soul 106.3 FM" had a synchronous sister station, WYRB, airing on the same frequency and serving Rockford and DeKalb, Illinois.

In August 2011, WSRB dropped the name "Real Radio" and switched back to calling itself "Soul 106-3", but the programming was initially unchanged.

Under the name brand change, it skewed its urban adult contemporary format to include classic hip hop in addition to R&B and soul music.
