October 2009 Meeting – Omneon

You all know by now that capturing and trimming audio and video for later playout is a big waste of time. Store and forward servers and versatile playout servers are all the rage now, because you cut out all that labor in the middle processes.

At the next Chapter 36 meeting, Vice President of Broadcast Market Development for Omneon, Paul Turner, presents an overview on File Based Workflows and compression—not one size fits all. TV Magic San Diego hosts the meeting  Wednesday, October 14. The meeting starts at 12:00 Noon and will end around 1:30PM. Omneon buys lunch. Call Eva at 858-650-3155 with any questions.

Paul recently had an article published in Broadcast Engineering covering “The New World of Codecs and Formats”. The article was an overview on file-based workflows.

August 2009 Meeting a Big Success

We beat all summer attendance records with 45 attending the chapter’s August 19 meeting this year featured a truck show and tell at Clear Channel Communications. Four specially outfitted rigs were there, from Clear Channel, CBS, KGTV Mc Graw-Hill, and the Federal Communications Commission.

Mike Prasser, CBS Radio San Diego market Director of Engineering, shows a simple but utilitarian studio inside the CBS truck. Electronics include telephones and interface gear, playout computer, CD player, microphones, and mixer. Just as important, it had air conditioning.

Scott Mason, CBS Radio Los Angeles market Director of Engineering headed up the fabrication of this Emergency Response Vehicle. He’s shown holding up the wall opposite the transmitter gear in the rear of the truck. Besides an FM transmitter, they have a wideband transmit vertical folded dipole and mast on-board. Scott serves also as liaison officer for chapter 36, and devoted his day to getting the rig to San Diego and back, and meeting our friendly engineers.

Host Clear Channel San Diego showed off its Emergency Response Vehicle serving Southern California radio markets. Like the CBS truck, it has a transmitter and antenna, studio equipment, and communications gear, as well as a generator trailer. Staffer Steve Frick, on-board in the blue shirt, demonstrated some of the gear inside. Dean Inhoff, also part of the Clear Channel team is in the red shirt. Director of Engineering John Rigg led the build-out team, and provided a parking lot for the Truck-O-Rama. Thanks, John!

KFMB-AM Files IBOC Interference Complaint Against KBRT

Managers at 760 kHz KFMB-AM say their signal is covered by hash in northern San Diego and throughout Orange County from the digital sidebands of alternate channel 740 kHz KBRT in Avalon on Catalina Island. Radio World’s Leslie Stimson recently filed a report about the battle. KBRT says KFMB has no right to interference protection in these areas since KFMB moved to the alternate channel in 1959 from 540kHz with the proviso of accepting interference outside its metro area of San Diego. KBRT also says it has reduced its IBOC sideband power by 6dB. Southern California has a few alternate channel combos that require stiff NRSC filters and cooperation–think 690 XETRA and 710 KSPN or 1070 KNX and 1090 XEPRS. But KBRT wants the Ibiquity IBOC system on the air, which by definition is “in-band” but not really “on channel”, typically spilling well into alternate channel territory. This one could become a national test case.

September 2009 Meeting – RDL

Tell me you haven’t at one time or another put a little Stick-On microphone preamp in a remote booth or edit room, or used a Stick-On mixer to feed an IFB circuit somewhere. How about a silence sense module to automatically switch between air and production for IFB?

Radio Design Labs, RDL, is the small company many of us have wished we’d thought of first. They make small modules designed to do some utility job and keep you from having to make it yourself or venture into lower quality equipment.

Chuck Smith of RDL stops by to meet us for lunch at TV Magic, September 16, noon. He’ll discuss the history of the company and talk about applications for their newest products. Members and guests welcome. TV Magic is at 8112 Engineer Road in Kearny Mesa.

KUSI to Become Regional Superstation?

McKinnon Broadcasting filed recently to construct new low power digital TV transmitters in three Southern California markets new to the station.

The applications include a 15kW channel 40 in El Centro, a 2kW channel 44 serving Santa Barbara, and a 5kW channel 26 serving Palm Springs.

FCC records show that two other groups have applied for channel 44 in Santa Barbara, and the FCC granted Gulf-California group in 2007 a construction permit for KCWQ-LD on channel 26 in Palm Springs.

KUSI already operates a channel 12 translator, K12PO, serving the Temecula area of Riverside County. They have an application to upgrade the site to digital.

Director of Engineering Richard Large said, “With the FCC opening up a window to file for Digital LPTV and translators, [the filing] was a new opportunity to expand our KUSINEWS coverage.”
