Armstrong Commemorative Broadcast Scheduled
Alpine, NJ - Apr 11, 2005 - In commemoration of the 70th anniversary of Major E.H. Armstrong's first public demonstration of wide band frequency modulation, Steve Hemphill, owner of Solid Electronics Laboratories, and Charles Sackermann Jr., the CEO of CSC Management, who is the owner of the Alpine Tower in Alpine, N.J., will transmit a commemorative FM broadcast from the Alpine Tower site on June 11 and 12, 2005.
The pair has secured Special Temporary Authority from the FCC to conduct the broadcast on Major Armstrong’s original FM frequency of 42.8MHz under experimental call sign WA2XMN.
The broadcast program material will consist of David Ossman's dramatic production of Empire of the Air, which is based on the book by Tom Lewis. Broadcast plans also include excerpts from a 1941 test broadcast between member stations of the original New England Yankee Network, featuring voice recordings of Major Armstrong himself, Paul deMars (Yankee Network chief engineer) and others.
There will also be a rebroadcast of the final sign off of Major Armstrong's pioneer FM station W2XMN/KE2XCC, which went dark on Feb. 25, 1954, after Major Armstrong's death. A streaming Webcast of the commemorative broadcast is also planned.

Digital Audio Services Expected to Boom
Mar 21, 2005 - Forrester Research released its study titled The Future Of Digital Audio, which examined the various forms of audio entertainment options available to consumers. In the report, Forrester notes that new digital audio services such as satellite radio, Internet radio, IBOC, podcasting and subscription and data service business models are changing the way consumers listen to radio. Terrestrial, Internet, satellite and podcasting radio are expected to grow steadily, and by 2010, 20.1 million households will listen to satellite radio and 12.3 million households will synchronize podcasts to their media players.
The report notes that consumer acceptance of HD Radio, Ibiquity's IBOC technology, will lag the other forms initially, but it will pick up closer to the end of this decade, reaching 9.7 million U.S. households by 2010.
Broadcast Electronics Starts Training for Consulting Engineers
Quincy, IL - Apr 13, 2005 - Broadcast Electronics will begin a series of engineering sessions specifically for consulting engineers starting June 1 at the Wyndham City Center hotel in Washington, DC. The company will introduce its Learn and Earn with BE educational series by offering an insider's look at two topics foremost on the consulting engineer’s radar screen:
- Basic system operating parameters - Spectral measurements - Equipment setup and installation - Evaluation of interference issues - Coverage issues - Issues unique to AM HD Radio installations
Consultants will learn the latest tools available from BE and techniques being used in the United States and Europe to specify a working synchronous FM system that is functional, FCC compliant and HD Radio compatible.
John Bisset, Northeast regional RF sales manager for Broadcast Electronics, notes that the goal of these sessions is to arm consulting engineers with the latest developments that are important to his trade. BE chose the Washington location because of its convenient location for many who are interested in these topics.
Consulting engineers who participate in these sessions will receive a certificate of participation from BE and also will be listed on the BE website as a resource for stations and groups seeking these services.
The two initial sessions will take place consecutively on the morning of June 1. They are being offered at no charge and a complementary lunch will be offered. Although the sessions are free, pre-registration is required. Consulting engineers can obtain agenda details and register for one or both by sending an e-mail to firstname.lastname@example.org.

Eye on IBOC
WGUC-FM Tests Neural Audio Surround Sound Technology
Cincinnati - Apr 12, 2005 - As part of its ongoing testing of surround sound technologies, WGUC-FM in Cincinnati has broadcast a previously recorded and produced performance of the Cincinnati Symphony Orchestra on March 20, 2005, using Neural Audio's digital audio technologies.
After testing Neural Audio's Neustar 5225 two-dimensional downmixer and Neural's SEE (Spatial Environment Engine) rendering system, Don Danko, WGUC vice resident of engineering noted that the performance of the Neural surround technology met or exceeded all of the station's criteria.
Alex Kosiorek, audio recording and mastering engineer of WGUC's Corbett Studio Audio Recording and Production facility said, "I am particularly pleased with the stereo downmix as compared to the original stereo mix. With minimal adjustments, the accuracy of the surround sound recording was faithfully reproduced."
WGUC spent two days at Neural Audio headquarters in Kirkland, WA, studying the surround technology in stereo and 5.1 listening rooms. WGUC and Corbett Studio original content was used in the review process. The station's review requirements included:
The Neural 5225 2D downmix system is scaleable for backward and forward compatibility allowing analog, digital, lossy, linear, stereo and 5.1 to co-exist in the existing broadcast environment. Audio is encoded with a watermarking to provide compatibility with existing 2.0 equipment.
