WRGX-LD is the low-powered, NBC- affiliated television station for the Wiregrass Region of Southeastern Alabama and the Florida Panhandle. Licensed to Dothan, Alabama, it broadcasts a high definition digital signal on UHF channel 23 from a transmitter in Bethlehem, Florida. Owned by Gray Television, the station is sister to CBS affiliate WTVY. The two outlets share studios on North Foster Street in Downtown Dothan.
In order to increase its off-air broadcasting reach, WRGX is simulcasted in standard definition on WTVY's fourth digital subchannel. This can be seen on UHF channel 36.4 (or virtual channel 4.4 via PSIP) from the same Bethlehem tower. On weekdays, WTVY produces two thirty-minute newscasts (at 4 and 5:30 p.m.) that are exclusive to WRGX. As a result, this station airs the NBC Nightly News taped delayed at 6 unlike most NBC outlets in the Central Time Zone.
The WRGX news programs broadcast from a secondary set at the North Foster Street facility. Although it features additional reporters from WTVY, this station maintains separate news anchors and a meteorologist. It does not simulcast any newscasts from WTVY.
