    • Wed 11/30: planned momentary outages of DT54 over the air signal

      (this is a continuation of the work originally announced for 11/28, which was not completed on Tuesday.) At some point during the morning of Wednesday Nov. 30th, the KQEH transmitter will switch from its main antenna to the auxillary one, to allow for the safety of workers doing maintenance for another TV station on the […]

    • Tues 11/29: DT54 Over the Air Signal restored

      Repairs have been completed on today’s transmitter issue, and the signals for DT54.1 through 54.5 have been restored.

    • Tues 11/29: DT54 Over the Air signal currently down

      (DT54.1 through 54.5) During the course of the work described below, which necessitated moving our outgoing signal from the main antenna to the auxillary antenna, the transmitter suddenly shut down. As of 3:30pm Tues, we do not have an estimated time for repair and return of the Over the Air signals for DT54.1 through 54.5
