March 2006 Meeting – A Product Fair, Dinner and a Little Tech Talk

It doesn’t get any better than this. Think of it as the “convention before the Convention,” March 15 downtown. Learn about planning your modern studio audio and control systems with a real industry systems guru. SCMS shows off their wares with an impressive array of products they represent: a digital mixer system, processors, mics, recorders, test equipment, and the famous new Receptor HD digital radio. SBE folds in a brief meeting, but this event is all about you and the goods.

Wednesday, March 15, we offer a three part evening of product fair, dinner, and technical presentation at Embassy Suites on the Embarcadero in downtown San Diego.

You can configure it as you wish, but we recommend dessert, a 7 PM presentation by Jay Tyler of Wheatstone called Planning for Digital Audio and Control Networked Facility.

At 4 PM, SCMS and Wheatstone bring an exhibition of broadcast goodies. Included are products from:

  • Aphex 230 The Master Voice Channel Processor
  • Orban 6200, AM HD Audio Processor
  • Digigram UAX200, Broadcast USB Audio Interface
  • Audio Science Various audio cards
  • Heil Microphone system including PR-40
  • HHB DRM85, Flash Mic Digital Recording Microphone
  • Tascam MDCD01, Mini Disc & CD Combo
  • Comrex STAC 6 Phone System, Access IP Audio Codec
  • NT Instruments Digilyzer, Digital Audio Analyzer
  • Burk Remote Control System
  • Genelec 8030A Bi-amplified studio monitor speaker
  • Vorsis AP-3, Digital Signal Processor
  • Boston Acoustics Receptor HD Digital Radio
  • Dielectric Communications Antennas

You can kick the tires and get a personal demo, from 4 PM. At 6:30 PM, the hotel serves a South of the Border buffet. Then the SBE brief meeting and Jay’s presentation.

RSVP with Doug Tharp, (619) 232-5600,  or Sandy Berenics, (858) 560-6679, so that the food order and space requirements come out right.

Location: Embassy Suites, 601 Pacific Highway, near Seaport Village.

John Rigg to Become Clear Channel San Diego Market DOE

Clear Channel Communications has named John Rigg to the position of
Director of Engineering for the San Diego market cluster. He had been
Radio Supervisor at KFMB AM/FM for the past four years. From 1994 to
2002, he had been staff engineer in radio and TV at the KFMB Stations
group. John succeeds Kevin Douglass, who had led the local engineering
crew since Jacor began accumulating stations here in 1996.

John will also oversee maintenance at the Finest City Broadcasting chain that was sold by Clear Channel to their previous FM General Manager Mike Glickenhaus. The Finest City chain, which includes XHITZ (FM), XETRA-FM, and XHRM (FM), occupies a separate partition in the same building in Kearny Mesa.

He supervises a crew of six veteran radio engineers, including John Morgan, John Barcroft, Ron Foo, Bill Thompson, Dean Imhoff, and Kevin Boyle.

John started in radio broadcasting in San Diego after a stint with Pacific Bell Telephone that included work with telco broadcast services. In 1989, he joined Edens Broadcasting, home of KKLQ AM and FM (now KOGO and KLNV). In 1993, they became part of Parr Broadcasting, which owned the KXST FM outlet on 102.1 (now KPRI). The next year he joined KFMB radio, where he worked for Tom Cox, later to move to the TV side until February of 2002, when he moved back to radio, but this time as Supervisor of KFMB AM and FM.

He joins Tom Cox again, who is Vice President of Engineering for the Western Region of Clear Channel Communications. John will answer to General Manager Bob Bollinger, who had been GM of KFMB radio stations when Tom and John worked there together.

John says that he sees a big challenge ahead overseeing the running of a such a large number of studios.

KFMB has not yet announced John’s successor.

Chapter Welcomes Fred Baumgartner

An SBE celebrity of sorts appeared at the annual December chapter banquet. Fred Baumgartner has joined the MediaFLO project at Qualcomm as the Director of Broadcast Engineering.

As opposed to the RF side of the project, Fred tells us that he is working the commercial insertion side. Fred is known for his FCC filing for a community-based low-power AM service in 2003, and for his work with the Ennes Educational Foundation Trust for the SBE. He is organizing an Ennes Workshop for the 2006 NAB Convention, this year with the theme “Everything RF”. He’s served at Senior Systems Engineer with Leitch Technology. He is currently commuting from his home near Denver, where he has been a member of Chapter 48, certified as a CPBE and CBNT. He’s also a licensed ham radio operator—KG0KI. We’re looking forward to seeing more of Fred at future chapter functions.

HDTV Returns to KPBS After Five Month Outage

Engineers at KPBS-TV report that their HDTV service is finally back on-the-air after a fatal failure of their encoder in July took it down. Dust off your remote and check out this battle story.

Early adopters of HDTV viewing in San Diego have long used KPBS-DT as their home system demo channel. It’s the only San Diego channel that outputs true high definition video 24 hours per day. And since the program material is commonly travel logs, music concerts, and nature shows, MPEG compression is kind to it. The video looks smashing. Enlightened consumer video dealers like Circuit City favored the channel for demonstration of their monitors because it was always there and it never showed a commercial for one of their competitors.

But that all came to a dead halt July 16 this year as the station’s first generation General Instruments encoder stopped outputting properly formatted bits. The video went blank, and audio sputtered on and off. Viewers reported that it would lock up their tuners.

The station continued, airing a simple digital simulcast of their analog content.

Director of Engineering Leon Messenie took time out from his winter vacation to chat about their troubles.

GS: Your old GI HDTV encoder broke down several months ago. Tell us about the battle getting a replacement.

LM: We actually started looking for a new ATSC encoder system after learning it was going to take about $325,000 to upgrade our current system to be able to handle Closed Captions on the standard definition channels. Since a complete new system would be much less we decided to replace our entire encoding system. I applied to CPB (Corporation for Public Broadcasting) in early 2005 for a grant to replace our old and out dated ATSC encoder system.  KPBS was awarded a grant and after looking at several systems we selected the Tandberg equipment. This work was started a few months before the HD encoder had the major failure. This brings us up to late August 2005 when we put in the order with Signasys Inc, a system integrator, to replace our current GI system with the new Tandberg system. That very same week our HD encoder had the major failure.  According to Motorola it was going to cost $9600 to repair and had a 6-8 week turn around time. Since we had just ordered a new Tandberg system that was supposed to be delivered in 6-8 weeks I could not see spending the money to fix the GI HD Encoder.

Then the delays from Tandberg kept coming and before you know it our HD was off the air from till December 22. All we could do is continue to broadcast the HD schedule in standard sefinition and wait until the new system arrived.

GS: I understand your Tandberg replacement didn’t work on the bench. Do you have any idea of when it will finally be up again?

LM: This is correct. The new system had a couple pieces fail right out of the box. Unfortunately they were the multiplexers, both main and backup. They had to go back to the factory via a stop in Atlanta, Tandberg’s USA headquarters. We were really trying to get the HD service up by Christmas 2005….

KPBS applied for an emergency grant from their foundation. When they got the funding this fall, the station ordered a Tandberg encoder and multiplexer. The unit arrived in early December, but on the bench, it appeared to be the victim of infant mortality. A replacement arrived just days before Christmas. After a hectic few days of testing, they were able to go to air December 23—about 160 days after the HD outage. Engineer Scott Stinson is still fine-tuning, and configuring the multiplexer for a flexible set of subchannels.
