KFMB-TV Signs Off Analog Signal After Nearly 60 Years

An era, nearly 60 years in the making, came to an end at 11:59pm on February 17th when KFMB-TV ceased analog broadcasting. KFMB was San Diego’s first television station when it went on the air in May of 1949 and is one of three broadcast stations in the nation’s 28th market, to transition to full time digital operations.

“The transition went smoothly, and just as we planned it” says Rich Lochmann, Director of Engineering for the KFMB Stations. Shortly before 11pm, Lochmann and Rick Bosscher, RF Systems Manager, were joined at the Mt Soledad transmitter site by former KFMB Engineer Frank Aamodt, and Chris Aamodt, current Senior Broadcast Maintenance Engineer at KFMB.

The Aamodts are father and son and represent two generations of engineers who have served the KFMB Stations. Frank Aamodt, who is 87, started at KFMB in 1948 even before the station was on the air and worked there for two decades as Assistant Chief Engineer.

Following a tour of the current broadcast facility, at 11:59pm, the senior Aamodt pressed the “off” button on the station’s analog transmitter. Following the rerouting of transmissions line, Aamodt then placed the new digital station on the air, by pressing the “on” button for the digital channel 8 VHF transmitter at around 12:20am, signaling a new era in San Diego television history. Aamodt called the event “exciting” and very different from the time he worked with transmitters and broadcast equipment. “In those days we didn’t have a lot of money so we had to make everything ourselves” says Aamodt who added that the digital broadcast technology is “amazing”.

San Diego DTVs Ready for Transition

Some San Diego broadcasters are making final preparations for the DTV transition at midnight tonight. KFMB and KGTV are shutting down their analog VHF transmitters on Mt. Soledad and putting digital transmitters on the air in their place. KSWB will stay on for a week with a “night light” consumer message about the transition.

KPBS Director of Engineering Leon Messenie says that his station will leave the analog channel 15 transmitter on through their March pledge drive. KNSD and KUSI now say they will wait until June 12 to drop their analog service.

The transition delay bill passed by Congress does not mandate a June 12 analog shutdown, but would give broadcasters that option, as well as fund an extended converter box discount coupon program. All network owned and operated stations will keep their analog transmitters on until June. KNSD is an NBC O&O station.

Meanwhile, XETV managers have declared their intention to turn over their analog channel 6 transmissions to another Televisa service. The exact date of the transition and content to be broadcast haven’t been determined.

Stations transitioning Tuesday night are preparing for a barrage of phone calls Wednesday morning. They expect to have additional staff members answer the phones and triage calls for the depth of their technical questions. KGTV has conducted a trade-in program for people who haven’t used their converter coupons to give them to viewers who need them.

Entravision stations, both Mexican LMA stations and US low powers, are attempting to convert to DTV. XHAS-DT in Tijuana, “T33”, signed on today for the first time on adjacent UHF channel 34. XHDTV Tecate is due to come on line soon on channel 47. KBNT has an application pending for a digital service on channel 14. The FCC signaled that it might approve that application for a low power service after stating in a recent ruling for LA County emergency services on channel 15 that its use in Los Angeles did not preclude reusing the channel for low power TV in San Diego. Channel 14 is similarly used for land mobile in the LA basin.

February 2009 Meeting – Middle Atlantic Discusses Thermodynamics

If you could see heat circulating around your equipment or server rooms, you’d find at least a few places where hot air is not gracefully returning to the air conditioner, or where you are pulling in already heated air into your equipment. Avoiding these situations takes some planning, and those who have already pondered the movement of heat waves have some great, simple ideas. For example, did you know you should just stack up hot servers right on top of each other rather than provide air gaps between them?

For our February meeting, Bob Schluter of Middle Atlantic Products discusses effective ways to control the temperature inside equipment racks, critical to the proper functioning and survival of the circuits operating within them. He can help you understand and calculate when to vent a rack using natural convection and when to use forced air (fans). Additionally, he will cover some basic power distribution topics, including AC magnetic fields and their effects on signal wiring as well as ground myths. Bob is a bit of a celebrity and a unique guy as both engineer and president.

Join us Wednesday, February 18, at noon at TV Magic, 8112 Engineer Road in Kearny Mesa, San Diego. T-shirts for the first 40 attendees and pizza lunch will be provided by Middle Atlantic Products. Lecture starts at about 12:30, and you should be on the road by 1:30 PM. Guests welcome. Hey, even if you worked on the digital transition, take a break and join us.

Eric Schecter Headed to Phoenix

Chapter 36 Chairman Eric Schecter has returned to his old position as Director of Engineering for the CBS cluster in Phoenix. He moved this month after leaving a similar job in San Diego at Lincoln Financial Services last fall. Eric resigned his office in the SBE last month when he received the job offer in Arizona.

The chapter will have to elect a replacement.

Before departing, Eric wrote us a message:

Dear Friends,

Please excuse the impersonal nature of this posting, and know that if I could write each of you individually, I would.

My arrival in San Diego four years ago was the culmination of a goal to come about as far West as anyone could.  My first opportunity back in 1996 didn’t quite work out, so when an opening to work in the America’s finest city in 2005 became available…well, it was irresistible!

Times and fortunes have changed dramatically since  ’05, and as you may know, I found myself with an unanticipated and extended “vacation” late last year. As they say, tea break over, back on your heads, and so it is that I will be leaving San Diego, and heading back to the inferno otherwise known as Phoenix. At least I get to regain my status as a Zonie!

It has been my distinct honor and pleasure to serve as your Chapter Chair for the past few years. Collectively, we’ve managed to turn the Chapter around by changing the meetings to Noontime affairs, increasing attendance and maintaining a healthy bank balance. Along the way, our esteemed webmaster and program chair, Gary Stigall, has won a National award for his hard work and dedication. I often hear other chapters comment that our site looks so good, and has such great content, that they are often tempted to do a cut ‘n’ paste! The members of Chapter 36 are some of the friendliest and most talented around.

I leave knowing that Chapter 36 is in good hands and wish all of you the best in 2009 and beyond.

Eric Schecter
Chapter 36 Chairman

Christyahna Gets New Lemon Grove AM CP

The FCC issued a construction permit for a new 1400 kHz AM station in Lemon Grove. The group operating the 2 watt KRLY-LP "Lite 107.9" in Alpine, Christyahna Broadcasting, had filed for the new 1000 watt local channel station in 2007, but Gold Coast Broadcasting, operating a co-channel AM station in Ventura County, had filed a petition to deny.

Christyahna principal Gerry Turro was past Chief Engineer at WNEW New York, then the operator of the famous "Jukebox Radio" network WJUX in northern New Jersey. The FCC eventually broke up the network of low power FM stations in 2003 after it was accused by competitors of improperly extending its coverage with translators outside its primary coverage area using fiber links to the various transmitters.
