On October 27th, Mexican TV stations aligned their virtual channel numbers with their network identifications. After re-scanning channels, you’ll find, for example, XHTJB Tijuana, physical channel 21, identifies now as 11-1 since it broadcasts Canal Once from Mexico City, replacing its most recent virtual channel number as 3-1. That last number had been its analog channel. XHJK, Azteca 13, physical channel 28, now identifies as 1-1.
Not all stations along the border are following this protocol. Tijuana’s Canal Las Estrellas, slated to be 2-1 throughout most of Mexico, was still 57-1 when last scanned. Stations were not re-identified if it was believed their virtual channel number would conflict with a US virtual channel ID.
US TV stations in major O&O markets at one time aligned their TV channel allocations with their mother networks. CBS stations signed on channel 2, NBC channel 4, DuMont channel 5, and ABC channel 7 wherever they could.
When broadcasters swap CD’s, cart machines, turntables and audio consoles for PC-based digital playout, mixing & processing systems, we call that Virtual Radio. At our next meeting, guest speaker Bill Bennett, Lawo’s Radio Applications lead in the U.S., will describe virtualization in greater detail by outlining the real applications in use today. He’ll explore how broadcasters may now reap operational benefits and gains by capitalizing on I.T.’s investment in R&D and will discuss virtualization’s anticipated role in content creation and broadcast workflow in the future.
Virtual Radio is a hot topic. A recent episode of This Week in Radio Tech (TWiRT) featured a Lawo presentation on this topic. How did they conduct their broadcast interview? Virtually, of course!
Lawo is a provider of virtual radio products, digital mixing consoles, routing systems, video solutions and turnkey systems for the professional broadcast industry. Their equipment is utilized by TV and radio stations, production companies, and theaters worldwide.
Bill Bennett made his presentation Wednesday, November 9th, 2016 at iHeartMedia, San Diego before a sizable audience of local broadcast engineers.

With all the discussion regarding studio video over IP, it gets a little nutty to try and sort out all the players trying to move the industry forward. Scott Barella, Deputy Chairman of the AIMS (Alliance for IP Media Solutions) Technical Work Group and the new CTO of Utah Scientific will explain the progress of IP video and how the standards groups of SMPTE, EBU, AES as well as industry groups such as VSF and AIMS are working together to help move the IP initiative forward.
He will also review the key differences of SMPTE 2022-6/7 and TR-03/04 and what the engineers are doing behind the scenes to make it all work together.
Scott will then also share where Utah Scientific is in their development of some key products enhancing existing systems that are raising a few eyebrows.
Join us for this bonus meeting Wednesday, September 21, at 12 noon at KFMB Stations, 7677 Engineer Road. Utah Scientific will pick up the tab for lunch. This is truly bleeding edge information that we’re lucky to see the day before the presentation is made in L.A.
Something we don’t talk a lot about are the precision electro-mechanical devices we use at the transmitter–the RF power metering, RF switch control, dummy loads, and so on. What goes into this gear? What’s the state of the art? We intend to take the wraps off this wizardry at this month’s SBE meeting. Bob Tarsio, President of Broadcast Devices Incorporated, will present information about the advanced devices used in transmitter plant infrastructure.
Bob spoke Wednesday, September 14th at KGTV in San Diego before a number of local engineers.
Bob’s been at BDI since 2002, when he left a 20 year stint at Viacom as their Director of Engineering. Earlier, he was a radio Chief Engineer at what was WLTW/WAXQ in New York.
In August 1980 I was in my second year of TV engineering at KTVZ Bend when my boss Jess Ortega and I were to be on a live, local call-in TV show at 7pm at the station, talking about TV reception. About 30 minutes before air time, the transmitter dumped. As in—we were off-the-air. We jumped into the truck dressed in our suits, drove to the transmitter site, and were able to immediately put it back on-the-air because it had cooled during our drive. The show was re-scheduled for the next evening. Continue reading Making Waves Editorial: To Chill or Not to Chill→
