Subchannels The stations' signals are
multiplexed: On digital subchannel 7.2, the station carries The365 television network; the subchannel is also carried on
Suddenlink Communications digital channel 247. The subchannel launched on December 14, 2005, as the "StormTracker 24/7 Weather Channel", a local weather service consisting of temperatures, weather conditions and a live feed of the station's
Doppler radar (branded as the "StormTracker 7 Live Doppler Network") on a rotating schedule; the subchannel affiliated with
This TV in December 2009, it later switched to
Bounce TV on January 1, 2012. On January 1, 2020, Circle debuted on 7.2, displacing Bounce TV to 7.4. Circle remained until the channel was shut down on December 31, 2023, being replaced by The365. On digital subchannel 7.3, the station carries
Telemundo; the subchannel is also carried on Suddenlink channel 22.
Analog-to-digital conversion The station installed its digital transmitter tower on September 23, 2005; on December 14, KLTV became the second television station in East Texas to launch a digital signal, broadcasting on
VHF channel 10. KLTV shut down its analog signal, over VHF channel 7, on June 12, 2009, the official date on which full-power television stations in the United States
transitioned from analog to digital broadcasts under federal mandate. The station's digital signal relocated from its pre-transition VHF channel 10 to channel 7 for post-transition operations.
Translators On July 27, 2021, Gray Television signed K31PR on the air as a full simulcast partner of the main KLTV signal. Both stations air an identical subchannel line-up, with K31PR's coverage area encompassed entirely by the larger KLTV signal. On March 14, 2023, digital translator K21PE-D was tested at its upgraded site on the KLTV tower, with a license to cover the new signal filed the following day. Concurrently, Gray Television filed a silent notification for K31PR-D, as the translator discontinued broadcasting on March 4, 2023, indicating that the company was doing so in preparation for the channel 31 facility to further upgrade through an upcoming filing. ==Availability==
