KGLA-DT is a digital-only television station that began broadcasting on June 5, 2007 under the callsign WHMM-DT. It is the Telemundo affiliate for the New Orleans DMA. It is licensed to Hammond, Louisiana, and broadcasts on UHF channel 42. As it is digital only, KGLA-DT's over-the-air signal is only receivable on sets equipped with HDTV tuners or Digital-to-SDTV tuner/conversion boxes. The station is also carried on selected cable systems in the New Orleans area. The owner of the station is Mayavision, Inc.
With an ERP of 1 megawatt, the maximum currently allowed by the FCC for DTV, KGLA-DT is the only full-power Spanish-language television station in the New Orleans market. The only other over-the-air Spanish-language station in the market is Azteca America affiliate WTNO-LP, a low-power station with limited coverage.
On August 27, 2007, WHMM-DT changed its call letters to KGLA-TV (after KGLA (AM), which Mayavision's president owns a 50 percent share of). On December 21 of that year, the -TV suffix was replaced with the -DT suffix in the station's callsign.
The station recently launched its own website.
