KDTN

The station's studios are co-located with Daystar headquarters off SH 121 in Bedford, and its transmitter is located on Tar Road in Cedar Hill, just south of the Dallas–Ellis county line.

In 1948, Variety Broadcasting, owned by Lee Segall), which already had KIXL 1040 AM (now KGGR) and 104.5 KIXL-FM (now KKDA-FM) wanted to add a television station.

Variety applied to the Federal Communications Commission (FCC) for a construction permit to build a television station on VHF channel 2, which would have been KIXL-TV.

Programs that have aired on KDTN during its tenure as a PBS station included The Joy of Painting, Sewing with Nancy, Sit and Be Fit, Plaza Sésamo (the Spanish counterpart of Sesame Street), This Old House, and occasional drama series such as Upstairs, Downstairs from ITV.

However, by special arrangement, KERA announced plans at the time to continue carrying programming sourced from the station on KDTN's digital signal, to free up bandwidth on KERA's main digital signal to allow the station to upgrade its main channel to transmit programming in high definition.

As of 2018, improvements in multiplexer technology allow KERA-TV to carry separate PBS Kids and Create subchannels without affecting picture quality.
