Lee McGowan Hospitalized–Update

Update June 18, 2013 by Mike Prasser at CBS Radio:

“Lee is in a rehabilitation facility and continues to recover from a procedure that he had a while back.

If anybody would like to send him well wishes, they can contact me at Mike.Prasser@cbsradio.com.”

Sam Bass at CBS Radio in San Diego reported in Facebook May 30:

Our long time chief engineer Lee McGowan is in the Critical Care at a local hospital and unable to receive visitors for the time being. We want to be ready to cheer him up when he feels better. I’m asking all of my radio friends who know Lee to please share some personal insights or memories. We want to make him feel loved and maybe have some laughs at the same time. Thank you all in advance.

I hope Lee gets well soon. My prayers for his full recovery.

Thanks to Bob Gonsett for passing on this bit of news. Bob adds:

Lee, you are one of my favorite people. Your combination of enthusiasm, curiosity and technical competence have made you a perfect fit for the job your’re in. Your story about “the tank, the tank!” is a classic. We all miss you and want to see you “back in the saddle” at the earliest possible moment. You’re in my prayers.

Well said, Bob. Lee has been engineering at KYXY 96.5 and 103.7 FM since the mid-1980s. Wishing you a speedy recovery, Lee.

Making Waves: Our Summer Jobs

(Commentary) For better or worse, I share much of my DNA with my father, Herb, who has throughout his 84-year life so far, insisted mostly on doing everything himself. The story I often tell to illustrate this point is about when we lived on a 40-acre ranch in Central Oregon requiring constant fence and pasture upkeep during the hours he wasn’t driving an oil truck full-time. He found termites in the bathroom of the old homestead and learned that they came from a path of dirt and wood from the ground. This wouldn’t do. So he reconstructed the substantial foundation, lifting the house with jacks and spooning mortar in the small spaces between lava rocks that he had dragged under the house one at a time. I know because I helped mix the mortar and pushed rocks through the vent openings to him.

You can run a broadcast engineering business like this, doing it all yourself. You can run cables and terminate them, install and configure equipment, assemble satellite dish kits and climb towers. It’s mostly intellectually engaging, you accumulate experience and leave each project with a pride of ownership.

It will also drain you because you can never keep up with all the work, you can’t take time off really, and you will limit your income potential greatly. This is  because you can’t charge enough for the installation work to cover all the overhead you don’t get paid for, like accounting, marketing, and purchasing.

This is one of the basic tenets of small business. Basically, if you are doing the busy work, you’re doing it wrong. A small business owner should be tending to strategic planning and business development, leveraging income by hiring good help to handle the day-to-day activities that make up the foundation of your technical service business.

Employee #1

As much as it goes against my instinct, I decided that when young students were between college terms earlier this month, it would be a good time to hire. I listed in Craigslist an opening for a broadcast engineering “apprentice.” I didn’t want to say “intern” because this is a real job and a paid position and in California the term intern has legal limitations when you are not paying (even though most employers seem to ignore the rules at their own peril). I believe that students or those looking todevelop careers deserve to be paid for their work, whether they are bringing real talents to the job or just working hard. In my opinion, there’s entirely too much slavery going on, and it’s hurting our economy by cutting off the income of people who should be out there consuming.

Within a few minutes of posting the opening, I got a resume and cover message from Julio Ramirez, a young man who seemed to fit my three needs: (1) self-initiated computer hobbyist who had dabbled in programming and/or networking, (2) a customer service attitude of respect and friendliness, and (3) long-term interest in broadcasting or something like it. I hired him the next day even though responses were still piling in. Some resumes were short on something, some were vastly overqualified and might suit a future full-time opening (or they should work independently!), but this one was just right.

So Julio and I have had our first week together, running and punching in UTP cables with another helper one day, finishing for me a complex batch file for a CALM Act audio monitoring program another day, and assisting with a commercial cueing problem I had been dealing with. Once a graphics student, he even had a logo designed for my badly ignored website before we could even get started. He’s learning new skills faster than a classroom lecture would give, and I’m clearing my TO DO list with rapid relief.

If you have some work to do that you’ve had to sideline while you grapple with your day-to-day, consider hiring someone from that huge pool of underemployed technicians out there. While you aren’t likely to find someone you can send to the transmitter for a quick fix, most broadcast work these days involves microprocessors and the kind of technical problems you can solve with Google searches, a technical mind, and time.

I took the big step to employer, and we’re going to have a terrific summer.

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 – Analog stations along the border are back on the air Friday 5/31 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.

Longtime XETV Engineer Francisco Laurent Passes

Francisco Laurent Martinez, who served as engineer and Chief Engineer of the Transmission Department at XETV in Tijuana from 1959 till this month, passed away March 24, 2013 in Tijuana. He saw the facility progress from a single English-language ABC affiliate for San Diego to a cluster of eight Televisa-operated TV stations, all now with solid-state transmitters and antennas on two self-supporting 500 foot towers.

He mentored engineer Humberto Borzani, who told us Francisco was born December 7th, 1930 in Tijuana. He graduated in 1956 as an Engineer with a major in Electronics and Communications in Mexico City. He served as Chief Engineer of the Radio Monitoring Station of SCT (the Mexican equivalent of the FCC) from 1972 to 1987. The SCT sent him to Washington to coordinate cross-border frequency allocation studies in 1979.

Francico served as professor at the Instituto Tecnológico de Tijuana from 1971 till 1987, and was founder of the associated cultural FM station Radio Tecnológico 88.7 MHz FM from 1987 till 2005.

On a personal note, I worked at XETV’s U.S. operations from 2004 till 2010, but was always warmly welcomed at the Mexican master control and transmission site. I have never seen a transmitter site like the one Francisco led, from the marble floor at the entrance and master control rooms to the spotless transmitter rooms to the twice-filtered air and shiny copper transmission lines. The 1955 GE transmitter was ready for air until just a few years ago. Their UPS and generator backups kept the transmitters going without interruption for years at a time. Francisco was justifiably proud of that facility, and he will be missed.

March 2013 Meeting: All About the High Efficiency Video Codec

Just when you thought your H.264 codecs were about as efficient as possible for transmitting your media files, along comes H.265. This new HEVC is likely to change everything. But how much more efficient is it? What exactly is different about it? How are vendors gearing up for the new codec? When will it be ready for prime time?

Chapter 36 is fortunate enough to bring to our March meeting highly regarded speaker Joel Wilhite from Harmonic.

Be sure to mark your calendar for 6:30 PM, March 28th at the KGTV studios, 4600 Air Way, near where the I-805 and CA-94 freeways meet. Note this special evening time and day. Harmonic will provide dinner at 6:30, followed by a brief business meeting and the presentation. RSVP so that we can get a good count for dinner to rsvp@sbe36.org.

Joel Wilhite has been a Broadcast Solutions Manager for Harmonic for 18 years, designing media compression and storage systems for news and programming originators. He’s frequently called on to update groups like SBE with technology presentations.
