KNSJ Getting Ready for Air

According to their website, new non-comm KNSJ installed their antenna at Monument Peak and expect to hit the air on 89.1 MHz as soon as they install their transmitter.  The FCC lists the station as having an ERP of 330 watts and city of license as Descanso, but the elevation will give the station a decent signal to line-of-sight locations throughout San Diego County. The organization behind the new station says in their mission statement:

Activist San Diego is a social justice organization that promotes and facilitates the development of an active, inter-related, progressive community in San Diego through networking, culture and electronic technology.

For the time being, listeners in the Pacific Beach, La Jolla, and University City areas shouldn’t expect much reception due to co-channel 4-watt K206AC in La Jolla that rebroadcasts KPBS-FM.

June 2013 Meeting – VITEC and IPTV

Michael Chorpash, Vice President of Sales at VITEC will discuss IPTV inside the enterprise LAN and outside Over The Top (OTT) across the WAN. This will cover encoding, transcoding, middleware IPTV management and display to multiple screens (desktops, TV’s and mobile devices). There will be practical examples of how systems are being used today in small and large organizations; from broadcasters replacing their in-house cable plant to organizations broadening their reach and control over their content through IP networks.

Join us Wednesday, June 19, noon at KGTV, 4600 Air Way in San Diego. VITEC buys your lunch in the cafeteria at 12 sharp (and we have to say that reviews about the food have been 100% positive), then we move to studio space for the 12:30 presentation. Members and guests welcome.

Tijuana Analog TV Stations Sign-off

UPDATE 7/22/2013 – Analog stations along the border are now off the air, apparently permanently after elections. 

UPDATE 5/13/2013- Analog stations along the border are back on the air today after electoral candidates complained about lack of exposure ahead of July 7 elections. 

Eight Tijuana TV stations went dark May 28, 2013 as the first broadcast market in Mexico to go all-digital, delayed a month from the previous target date of April 16. Those stations included:

  • XHTJB channel 3, affiliated with Once TV, public/educational
  • XETV channel 6, Televisa O&O, affiliated with Canal 5
  • XEWT channel 12, Televisa O&O, affiliated with multiple networks
  • XHTIT channel 21, TV Azteca O&O, affiliated with Azteca 7
  • XHJK channel 27, TV Azteca O&O, affiliated with Azteca 13
  • XHAS channel 33, Entravision operated, affiliated with Telemundo
  • XHBJ channel 45, Cadena owned and Televisa operated, affiliated with Galavision
  • XHUAA channel 57, Televisa O&O, affiliated with Canal de Estrellas

Notably, XETV had just celebrated 60 years of broadcasting, having signed on with English language broadcasting in 1953 and continuing to do so until last year, when it switched to Televisa’s Spanish-language broadcasts of Canal Cinco. XETV-DT was the first digital TV station to broadcast in Mexico in 2000, and likely the inspiration for having Tijuana selected as the first market to shutdown its analog TV.

Mexico’s EFE indicates that over 192,000 free digital TV converters were passed out to Tijuana area residents as part of the transition. Unconfirmed statistics have 48% of Tijuana residents receiving their TV via free over-the-air broadcasts.

Interestingly, Entravision-operated XHDTV on Cerro Bola near Tecate remains on the air on channel 49. The next shutdown date, November 26, 2013 is supposed to include Mexicali, but it is not known whether XHDTV will shutdown at that time.

What is not yet known is how the empty channels will affect FCC-mandated repacking of TV channels along the border. There’s likely to be a scramble on both sides of the border to occupy the empty lower UHF channels.

May 2013 Meeting – Nautel

Ellis Terry visited Chapter 36 this month to update us on new technology at Nautel. Their Analog NVLT FM transmitter series now includes models from 3.5kW to 40kW, and they introduced a Nautel NT series of low power TV transmitters with the Nautel AUI and built-in test instruments.

Many thanks to Nautel for the lunch and to KGTV for hosting the meeting at its facility.
