WPWX (92.3 FM) is an Urban Contemporary radio station licensed to Hammond, Indiana and serving the Chicagoland region in addition to northwest Indiana, and is owned by Crawford Broadcasting. The station broadcasts from a transmitter a few hundred feet west of the Illinois/Indiana state line in Burnham, Illinois, with studios on Calumet Avenue in Hammond.
WPWX's urban format debuted in the spring of 2001 in an attempt to go head to head with the longtime urban radio leader in Chicago, WGCI-FM (Crawford Broadcasting previously had a Christian talk format on the 92.3 frequency for over 40 years under the call letters WYCA). The WYCA call letters were in use from 1959-2001. WPWX currently is the Chicago home to The Rickey Smiley Morning Show, and at one time carried both the Doug Banks Morning Show and The Tom Joyner Morning Show (both of whom worked at WGCI from the late 80's until the mid-90's). WPWX radio personalities include Shagg, DJ Pharris, Ozman, Young Si, Maha, DJ Nehpets, Jade, Paris Taylor, Mic Jonez, G Skee, Hot Rod, & Rickey Rampage. The station also features mixers DJ Am Pm, DJ K-Ceasar, DJ Big Pat & DJ Allstyle.
The station began broadcasting on September 14, 1949, using the call letters WJIZ-FM. The call letters WJOB-FM were used from 1955-1959, then WYCA from 1959-2001.
All Crawford Broadcasting Company radio stations broadcast in digital HD Radio, and all Crawford FM's also broadcast both HD1 & HD2 (digital) audio. Urban Gospel sister station WYCA, known as Rejoice 102.3, is simulcast on WPWX HD2. WPWX broadcasts two channels in the HD Radio format:
