Public license information: Profile

KNSO, virtual channel 51 (VHF digital channel 11), is an Telemundo-affiliated television station located in Fresno, California, United States. The station is owned by the NBCUniversal Owned Television Stations subsidiary of NBCUniversal; Serestar Communications operates KNSO under a time brokerage agreement. The station maintains studio facilities located on River Park Place in northwest Fresno, and its transmitter is located on Bear Mountain (near Meadow Lakes).


The station first signed on the air on March 22, 1996; originally operating as an independent station, it was originally owned by Sainte Partners II, L.P. During its first two years on the air, KNSO aired religious programming during the morning hours and Asian language programming in the afternoons, as well as programming from the California Music Channel. These programs were largely simulcast via San Francisco independent station KTSF-TV.

In July 1998, KNSO entered into a local marketing agreement with Pappas Telecasting Companies, then-owners of Fox affiliate KMPH-TV (channel 26); Papps then signed an affiliation agreement to make KNSO the market's WB affiliate, taking the affiliation from Clovis-based KGMC (channel 43). On January 1, 2001, KNSO swapped affiliations with KFRE-TV (channel 59), becoming a Telemundo affiliate; shortly beforehand, Pappas entered into an LMA with KFRE, resulting in the WB affiliation being relocated to KFRE. The station became a Telemundo owned-and-operated station, when the network's then-new parent company NBC bought the station in May 2003.

In March 2004, KNSO vacated its McKinley Road studios and moved to a new facility in North Fresno at 30 River Park Place. The station also implemented an advanced operational environment, making KNSO one of the most advanced television stations in the country. This experimental operation system allowed for a "limited intervention" master control center, which involves a highly automated system of operation. The station automation systems are almost completely self-reliant and provide for little to no assistance by the station personnel in running the on-air switching, monitoring and logging. This system utilizes the Florical Airboss, centralized sales and traffic systems, and various Grass Valley Group broadcast systems, including the Profile XP and Concerto. This experimental operation system has proved successful, and has now been implemented in other station operation control centers.

ZGS Communications took over the operations of KNSO (as well as San Antonio sister station KVDA) on May 1, 2009, although NBC retains the licenses to both stations.[1]

In 2014,[when?] Serestar Communications assumed the operations of the station. NBCUniversal retained the license.[citation needed]

Digital television[edit]

Digital channels[edit]

The station's digital channel is multiplexed:

Channel Video Aspect PSIP Short Name Programming[2]

51.2 480i 4:3 TeleXitos

Analog-to-digital conversion[edit]

KNSO shut down its analog signal, over UHF channel 51, 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 was relocated from its pre-transition VHF channel 5 to VHF channel 11.[3] Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 51.

As part of the SAFER Act,[4] KNSO kept its analog signal on the air until June 26 to inform viewers of the digital television transition through a loop of public service announcements from the National Association of Broadcasters.

News operation[edit]

After reaching its affiliation with Telemundo it launched a news department to compete with KFTV-DT. With news at 6pm and 11pm. Then because of reduced cuts by it parent company NBCUniversal it was replace with a hubbed news from Telemundo Production Center.

In 2012 it relaunched it's news department at 6pm and 11pm titled Noticiero Telemundo Fresno. Noticiero Telemundo Fresno was produced out of sister station KSTS-TV that station hired a reporter named Lucero Benitez who relocated to Fresno to be the local reporter. Anchors Cesar Bayona and Blanca Garza KSTS 6pm and 11pm anchors anchored the fresno newscast and Juan Francisco Ramirez handled sports. The newscast was pre-taped. The newscast later rebranded to Noticiero Fresno 51, after KSTS announced it's expanding that station's newscast and was adding a morning newscast. Noticiero Fresno 51 stopped production and was cancelled. That local reporter Lucero Benitez returned to KSTS to be a reporter for a new morning newscast that KSTS announced. In late 2014 KNSO started doing morning and afternoon news breves during Un Nuevo Día and Telemundo's afternoon programming.
