It’s hard to find much about Jacksonville, Florida’s WVOJ-AM. It appears to have signed on in the 1940s. By the 1970s, it adopted a country format.
At some point in the 1980s, WVOJ became a religious station (the call letters were said to stand for “Wonderful Voice of Jesus). It later became WQIK.
It went through a few more sets of call letters between 1994 and 2010, including WJGR, WBOB and the current WJNJ. As of 2017, New Covenant Ministries owns the station, which has a Gospel format. It is simulcast on 103.7 FM.
