FAA Issues NPRM That Affects Broadcasters
Washington - Aug 3, 2006 - In June, the Federal Aviation Administration issued a Notice of Proposed Rulemaking that on the surface appears to have a legitimate goal at its core, but in reality could become a burden to most radio broadcasters if adopted. The FAA intends to modify a section of 14 CFR Part 77 in FAA Docket FAA-2006-25002. The NPRM is titled Safe, Efficient Use and Preservation of the Navigable Airspace.
In the notice, the FAA wants to add notification requirements and obstruction standards for electromagnetic interference. The section titled EMI Notice Requirements states that the FAA proposes to "require notice of new construction or alteration that may result in EMI to air navigation, radio communication, surveillance services and facilities." It goes on to specify that a notice must be filed for any" construction of a new, or modification of an existing facility, i.e. -- building, antenna structure, or any other man-made structure, which supports a radiating element(s) for the purpose off radio frequency transmission operating on the following frequencies."
The listed frequencies are:
FAA notice would cover modifications to a tower or antenna, an increase in radiated power greater than 3dB, a change in authorized frequency and other facility modifications.
Read the NPRM at the Dept. of Transportation Document Management System website at dmses.dot.gov/docimages/p86/406317.pdf.
Comments are due by Sept. 11 and can be submitted online at dms.dot.gov/submit.
AES Expands Electrical Engineering Programs
San Francisco - Aug 2, 2006 - A substantial increase in electrical engineering-focused programming for the upcoming Audio Engineering Society Convention (Oct. 5 to Oct. 8), signals an AES effort to reach out to electrical engineers. The 121st Committee Tutorial and Master Class co-chairmen Bob Moses and Valerie Tyler have coordinated a variety of presentations by preeminent members of the electrical engineering community, including Robert Pease, Henry Ott, Bill Whitlock, Marina Bosi and Karlheinz Brandenburg.
What''s All This Analog Stuff Anyhow? - One of the most intriguing titles will feature analog guru Robert Pease of National Semiconductor, presenting his unique perspective on analog design for audio equipment. A scientist and prolific author, Pease was recently inducted into the Electronic Engineering Hall of Fame in the company of such innovators as Guglielmo Marconi and Thomas Edison.
Partitioning and Layout of a Mixed Signal PCB - Henry W. Ott of Henry Ott Consultants will address the issue of inherent problems found in controlling noise on a mixed-signal printed-circuit board. The presentation will demonstrate that component placement, partitioning, proper board topology and routing discipline, are the keys to laying a quiet mixed-signal PCB.
Audio Data Compression - Presented by past AES president Marina Bosi, (MPEG LA - Denver) and Karlheinz Brandenburg, (Fraunhofer IIS/AEMT - Ilmenau, Germany). MP3 and other audio codecs have become an intrinsic part of our daily lives. Applications range from digital radio and TV to digital sound on film, DVD and multimedia/Internet audio. Demonstrations will allow participants to evaluate different aspects of the audio coding process, potential artifacts and state-of-the-art implementations.
Grounding and Shielding - Bill Whitlock-(Jensen Transformers-Chatsworth, CA) Many audio/video system designers and installers think of grounding and interfacing as a black art. Do signal cables really pick up noise from the air like a radio receiver? Equipment manufacturers, installers and users rarely understand the real sources of system noise and ground loop problems and they routinely overlook or ignore basic laws of physics. Cutting through myth and misinformation, this tutorial will bring insight and knowledge to the subject.
Balanced Interfaces - Bill Whitlock-(Jensen Transformers-Chatsworth, CA) One goal in the design of audio equipment is to maintain a high signal-to-noise ratio. Balanced interfaces are capable of conveying wide dynamic range analog audio signals while providing them with immunity to interference. Realizing this full capability in real world, mass-produced equipment need not be costly. Whitlock will address several common mistakes made by equipment designers and discuss methods of effectively compensating for them.
Communications Expert Ken Schmidt to Keynote NAB Radio Show
Washington - Aug 2, 2006 - Communications expert and former Harley-Davidson spokesman Ken Schmidt will provide the keynote address during The NAB Radio Show in Dallas. Schmidt, who helped rejuvenate Harley-Davidson's reputation as an American corporate icon, will tell radio executives how to build a culture that rekindles relationships with listeners while reaching out to new ones in completely untraditional ways.
Schmidt, a specialist in corporate positioning and media relations, began his career with Harley-Davidson when he was asked to restore the then-struggling Harley-Davidson's image and create demand for its motorcycles. Within a few years, Harley-Davidson became one America's most recognized brands, while sales of its motorcycles soared. Schmidt became director of corporate and financial communications, serving as primary spokesman to the media and the financial communities.
Schmidt left Harley-Davidson to take an ownership position with Chicago-based marketing firm VSA Partners. In addition to Harley-Davidson, VSA serves General Motors, Coca-Cola, IBM and Campbell's Soup. He later sold his portion of VSA to start his own business, Ken Schmidt Company.
The keynote address follows the opening remarks by NAB President David K. Rehr and is slated for 10:30 a.m. on Sept. 21.
New HD Radio Ad Campaign Begins
Orlando - Jul 31, 2006 - The HD Digital Radio Alliance has unveiled a new effort to promote HD Radio that includes a series of radio ads. Leading the effort is a new tagline: Discover it! The effort is part of the alliance's partner-station advertising campaign that was announced in December.
The campaign promotes HD Radio as being "free, digital-quality radio programming" that offers "stations between the stations." The campaign has been launched in nearly all the top 50 radio markets.
The alliance's press release references the $200 million ad campaign that was announced in December and states that the effort makes the HD Digital Radio Alliance the number one or two largest radio advertiser in each market with more than 90 spots running in each of those markets. This is somewhat misleading since the alliance is not actually buying the time, but rather stations are running the ads on their own inventory.
The focus of the campaign is targeted at piquing the interest of radio listeners with the vague references to station between the stations. The escalated effort may work as long as consumers can ask for HD Radio in stores and actually find HD Radio receivers.
