NAB Engineering Handbook: Antenna System Moment Method Modeling

Posted in Radio on Nov 13, 2017

Cris Alexander, Radio Magazine

Cris Alexander is a well-known name in our field and composed Chapter 7.13 “Antenna System Moment Method Modeling.”

Radio Magazine: The 11th edition is a compendium of knowledge about radio and TV broadcasting gained over the last 100 years. It`s overwhelming really. Who should be reading your chapter on the method of moments?

Cris Alexander: Engineers who are responsible for the care and feeding of AM directional antennas would benefit most from the chapter on moment method modeling of AM antennas, particularly those who have for years been running full and partial proofs and chasing drifting monitor point values. Any engineer who has been frustrated at constantly having to deal with reradiators such as wireless towers and power line supports would benefit from this as well.

SAVE THE DATE AND PRE-REGISTER FOR YOUR LUNCH!

SBE Chapter 34 is hosting a lunch, sponsored by Bob Orban of Orban Associates on Wednesday, October 25 at 12noon at the New Mexico Broadcasters Association.

In 1970, Bob founded Orban Associates, originally as a manufacturer of studio equipment. In 1975, Orban Associates introduced the original Optimod-FM 8000, which was the first in a long line of broadcast audio processors for AM, FM, TV and digital broadcasting from the company. Orban has also been involved in professional recording for many years and has mixed several records released on the Warner Brothers label, as well as on small independent labels. As a composer, his music has been heard on classical radio stations in New York and San Francisco, and his score for a short film, "Dead Pan," was heard on PBS television in Chicago. He has designed studio reverberators, stereo synthesizers, compressors, parametric equalizers, enhancers, and de-essers under both the Orban and dbx brand names.

Bob Orban has been actively involved in NRSC committee AM improvement work. He has been widely published in both the trade and revered press (including Audio Engineering Society, Proceedings of the Society of Automotive Engineers, and SMPTE). He co-authored the chapter on "Transmission Audio Processing" in the NAB Engineering Handbook, 10th edition. He currently holds over 20 U.S. patents. In 1973 he was elected a Fellow of the Audio Engineering Society. In 1993, he shared with Dolby Laboratories a Scientific and Engineering Award from the Academy of Motion Picture Arts and Sciences. In 1995, he received the NAB Radio Engineering Achievement Award. In 2002, he received the Innovator award from Radio Magazine.

Recently Orban introduced the Optimod PCn 1600, the first Optimod that runs natively on the host computer`s Intel x86 processor; the software does not use dedicated DSP chips.

To attend this informative luncheon, please RSVP to Evan Baker today. 

 

National EAS Test Results Look Positive, But There Are Issues

Posted in Engineering on Sep 29, 2017

Concerns over audio quality, IPAWS poll

Phil Kurz, TV Technology
 
WASHINGTON—Anecdotal evidence points to general success of yesterday’s national EAS system test, according to broadcasters and a major EAS equipment vendor. However, despite the test’s overall success, a nagging known problem stemming from FCC rules that require no delay in the turnaround and transmission of EAS messages persists.

“Overall, from the information that we have gotten so far, it sounds like the EAS test was a success,” says Ed Czarnecki, senior director, Strategic & Government Affairs at Monroe Electronics.
