KNVO, virtual channel 48 (UHF digital channel 49), is a Univision-affiliated television station licensed McAllen, Texas, United States and serving the Rio Grande Valley metropolitan area. Owned by Entravision Communications (minority owned by Univision's parent, Univision Communications), it is a sister station to Fox/MyNetworkTV affiliates KFXV-LD and KXFX-CD, The CW Plus affiliate KCWT-CD and UniMás affiliate KTFV-CD; Entravision also operates Mexican station (and also a CW Plus affiliate) XHRIO-TDT. The five stations share studio facilities located in the Entravision Building, on North Jackson Road, in McAllen; KNVO's transmitter is located on Farm to Market Road 493, near Donna.
The Federal Communications Commission granted an original construction permit on October 9, 1983, to build a television station licensed in McAllen. Originally, the station was approved for 4071 kW to broadcast on UHF channel 48, but was later changed to 3162 kW on April 16, 1992. The station made its debut on October 12, 1992. During station's first years on the air, KNVO quickly becomes the highest-rated station in the market.
In 1996, LS Broadcasting, Ltd., Mundo Vision Broadcasting Company and Larry Safir (the owners of the station) station sold the licensee of KNVO to Entravision Communications for $24,8 million. Sale was completed on January 24, 1997.
On October 11, 2001, the Federal Communications Commission granted a permit to construct the station's digital facilities (requested in 1999). The station completed construction of its full-power digital facilities in June 2006, and was granted a license on June 26, 2007.
The station's digital channel is multiplexed:
|Channel||Video||Aspect||PSIP Short Name||Programming|
|48.1||1080i||16:9||KNVO-DT||Main KNVO programming / Univision|
|48.2||480i||4:3||KNVO-2||Simulcast of KTFV-CD / UniMás|
|48.4||KNVO-4||Simulcast of KCWT-CD / The CW Plus|
KNVO shut down its analog signal, over UHF channel 48, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 49. Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 48.
KNVO's newscast debuted in 1999. The station presently broadcasts 7 hours of locally produced newscasts each week (with 1 hour on weekdays, and 1 hour each on Saturdays and Sundays). In September 2010, KNVO started broadcasting local news in high definition.
In early December 2015, Entravision cancelled the morning newscasts in all of its stations in the United States (included local program Alegre Despertar).
