WJOX (690 kHz, "Jox 3") is a commercial AM radio station licensed to Birmingham, Alabama.

Because AM 690 is a Canadian and Mexican clear channel frequency, WJOX must significantly drop its power at sunset to 500 watts to avoid interference.

[4] WJOX is Alabama's primary entry point station for the Emergency Alert System.

Throughout the 1960s and into the 1970s, WVOK was a Top 40 station calling itself "The Mighty 690" with a signal that covered almost all of north and central Alabama, as well as parts of Mississippi, Georgia and Tennessee.

Rather than attempting to compete with crosstown station (and market leader) WSGN, WVOK targeted listeners in the rural areas of the states its signal reached.

Throughout the 1960s and 1970s, these concerts brought such performers as the Rolling Stones, Jerry Lee Lewis, Neil Diamond and the Beach Boys to Birmingham.

During the late 1980s and early 1990s, several AM stations in Birmingham debuted afternoon sports talk call-in shows.

In 1990, Herb Winches, a former TV sports anchor on WBRC and WVTM, moved his own popular show with co-host Ben Cook from WERC to WVOK.

The station airs 10 University of Alabama at Birmingham baseball games each season as part of the Blazers ISP Sports Network.
