May 20 Meeting: Grass Valley and the Role of IP Broadcast Infrastructure

The presentation will be an overview of IP based broadcast infrastructures.  We address some of the fundamental questions broadcasters have been asking.  Why do we even want IP at our core?  What advantages do IP-based designs bring to my facility?  What liabilities do IP designs bring to broadcast systems? We’ll cover current and emerging SMTPE standards on equipment and how current baseband technology will migrate into the IP world.

Join us Wednesday, May 20, at noon at KGTV, 4600 Air Way in San Diego, at I-805 and CA-94. Grass Valley will buy lunch. Everyone is welcome.

Scott Mason Remembered

We learned that Scott Mason, SBE board member and longtime KROQ chief engineer and air personality died Sunday morning, April 19.

San Diego members may not know Scott, though we had a highly attended meeting a few years ago in which we had emergency and FCC monitoring vehicles on display at Clear Channel studios. Scott hauled from Los Angeles the regional CBS Radio emergency backup trailer outfitted with transmitters and antennas, and gave an educational tour.

Scott Mason

He served on the SBE Board of Directors for many years and I was lucky enough to have served with him from 2012 to 2014. He was always generous of his time, having been not only as a leader for Los Angeles SBE Chapter 47, but for Boy Scouts and for Red Cross first aid classes. His most recent title at CBS Radio was West Coast Regional Engineering Director.

What fascinated me was his history at KROQ (FM) in LA. Since 1979, he served both as an on-air personality and engineer. He hosted “Love Line” until quite recently.

But Scott had health problems and went through a kidney transplant in 2013. It was quite a story, with a CBS Radio co-worker supplying the kidney. He did not look healthy and happy at our last meeting.

You can read more about Scott at a memorial page created in his honor at KROQ.CBSlocal.com.

FCC Memo Says San Diego Field Office May Close

Articles in Radio World and ARRL websites last week each quote internal FCC memos saying the Enforcement Bureau is set to reduce its field staff by half and close two-thirds of its field offices, including the one in San Diego. In the memo, EB Chief Travis LeBlanc and FCC Managing Director Jon Wilkins said the Bureau needed to take “a fresh look” at its 20-year-old operating model in light of technology changes and tighter budgets.

Under the plan, in the southwest, the Los Angeles field office would remain open, and Phoenix would have detection equipment in place but San Diego’s office would permanently close.

Part of the staff reduction plan would include creating a “Tiger Team” of agents “flexible enough to support other high-priority initiatives.” Under the plan, all field agents would have engineering backgrounds “to support the primary focus on RF spectrum enforcement.”

Apparently management would not be immune from the cuts, with director positions shrinking from 21 to 5, and administrative support positions from 10 down to 3.

March 18 Meeting: Orban Regarding Radio Loudness

We all went through the TV loudness discussion and regulations. How about radio and netcasting? Bob Orban will give a remote presentation to Chapter 36 about just this:

 My main topic will be the relationship between the fairly recent  ITU-R BS.1770 loudness measurement standard and non-television applications such as FM radio and audio-only netcasting: what “target loudness” is and how it applies to audio-only services. I will also briefly touch upon low bitrate compression artifacts and how things have changed with the widespread adoption of the MPEG4 HE-AAC codec.

Join us and learn something! It’s Wednesday, March 18, at 12 noon at iHeartMedia, 9660 Granite Ridge Road, San Diego. Orban will provide a light lunch. Members and guests welcome.

Woodson LPTV KZTC Flash Cuts to Digital

Mt. Woodson channel 7 VHF low power station KZTC flash cut to digital ATSC February 22. KZTC outputs a 1.5kW directional signal aimed at the southwest quadrant toward San Diego. The station had been rebroadcasting Entravision XHDTV’s MundoFox subchannel, but now rebroadcasts the same station’s English language services that include the Fox MyTV network and syndicated content.

KZTC is maintained, and partially owned, by Matt Lunati, who had been a fixture in San Diego broadcast engineering, but lately has been working servicing telecom sites in Arizona.

FCC Takes More San Diego Area LPFM Actions

On January 12, 2015, the FCC ordered in a single document the granting of an LPFM station for San Diego Catholic Radio and dismissal of applications from Active Pulse and Hi Neighbor. SDCR was given the right to construct its station on 93.7 MHz at iHeartMedia’s historic KLSD-AM/KGB-FM facility at Oak Park.

In summary, the FCC agreed with SDCR’s objection to Active Pulse’s application on grounds that the organization had no state record of being a non-profit organization. Hi Neighbor had earlier affiliated itself with AP in the mutually exclusive group.

93.7 MHz is currently occupied locally by 10W translator K229BO on Mt. Woodson rebroadcasting KPFK from Los Angeles after 90.7 MHz signed on in Tijuana.

Zack Takes Over Western Radio Electronics Store

No sooner had Western Radio Electronics moved its store back to Kearny Mesa from Mira Mesa than Zack Electronics swept in and purchased its assets and sent its employees home. Mike Richards, who sold supplies at Western for 32 years total, said he was laid off in October.

It’s no secret that electronics retailing has suffered from a combination of increased web mail order purchasing and a decrease in do-it-yourself hobby activity as modern electronics has used large scale integration techniques increasingly difficult to build and test. In San Diego, only Willy’s Electronics remains as a strong source of audio/video installation supplies and electronic components. Gateway Electronics and its derivative SD Electronics have closed.

Mike said that all stock was sent to Zack during by end of August from a temporary facility on Convoy Court. “I understand Zack has a will call department and counter but no real storefront as majority of sales are by phone or internet,” he said.

“At the time I officially retired from Western Radio I had been with the company starting downtown in 1973 working in the stock room and shipping department, and filled in on counter sales for only 2 years, at which time I was hired by Honor Marine Communications to be a buyer and estimator for repairs and maintenance on the tuna boats (also did some bench repair work when needed in shop).

“I was re-hired by Western Radio in 1984 to become Purchasing Manager upon retirement of the head of that department. At the high of Western Radio I was managing 2 additional buyers, 1 purchasing clerk, and shipping and receiving personnel.”

Jim Dujiwich bought the company in 2004 and moved it to Mira Mesa, where it floundered with low inventory and a poor location.

Mike continued, “It was always fun and really enjoyed getting to know all the customers of Western Radio. It was sad for me to see an institution close down that had been in San Diego since 1932, but as we all know, times change and local distribution just could not maintain the kind of sales that almost all manufactures wanted to retain dealerships.”

Mike is continuing with a side business he has had since 1971, setting up live sound events, and consulting and design work for small- to medium-sized churches, resorts, and businesses. Anyone can email him at soundbymike@gmail.com.
