FCC to Automatically Delete Unconstructed Permits from ULS
Washington - Dec 20, 2005 - On Jan. 21, 2005, the Wireless Telecommunications Bureau of the FCC issued a public notice announcing that it had initiated the development of an automated feature in its Universal Licensing System (ULS) for all wireless services that will identify those licenses, locations or frequencies for which a timely notice of construction or a request for an extension of the construction or coverage period has not been filed by the required deadline. Where the Wireless Service includes construction or coverage requirements and the licensee fails to submit a notice of construction or request for an extension in a timely manner, ULS will notify the licensee that its license, location or frequency has automatically terminated and will list the license, location or frequency on a weekly public notice as automatically terminated.
The Bureau originally planned to implement this process in June 2005, but postponed the effective date to allow additional time for licensees to submit late-filed construction notifications along with requests for waiver of the notification deadline. The effective date was further delayed by Hurricanes Katrina, Rita and Wilma.
The FCC will implement its ULS Automated Termination process on Feb. 1, 2006. The FCC released a public notice to allow licensees to file construction notifications and requests for extensions of construction deadlines.
The FCC will also release another public notice outlining the procedures involved under this Automated Termination feature in ULS. Information on construction or coverage requirements, and instructions on how to file a notice of construction or a request for an extension of time are available at wireless.fcc.gov/licensing/const-req.
The Society of Broadcast Engineers is preparing a checklist to help stations ensure that they are prepared for the pending deadline without risk of automatically losing potentially affected licenses.
Soundexchange to Audit Internet Music Sites
Washington - Dec 23, 2005 – Soundexchange, the sole entity designated by the United States Copyright Office to collect royalties from noninteractive Internet music services that stream sound recordings pursuant to compulsory licenses established by Congress, has announced a plan to begin auditing digital music services to ensure that they are accurately paying royalties that are due copyright owners and performers.
Soundexchange is starting its enforcement program by focusing on the sites that would owe the most royalties under the statutory licenses. The audits will begin sometime after Feb. 1, 2006, and will cover the years 2002, 2003 and 2004.
Soundexchange released a list of the streamers, which includes AOL, Beethoven.com, Bonneville International, Clear Channel Communications, Cox Radio Interactive, Live365 and Susquehanna Radio. Soundexchange spokemen said that organization intends to commence regular audits of services to ensure that services are competing on a level playing field.
Senate Confirms FCC Commissioners
Washington - Dec 21, 2005 - The United States Senate has confirmed Tennessee regulator Deborah Tate to fill the Republican seat on the Federal Communications Commission and Michael Copps to serve another term in a Democrat seat. A voice vote confirmed the nominations. President Bush has not yet nominated anyone for the remaining Republican seat.
Tate fills the remaining portion of a five-year term that expires June 30, 2007. She has been a director at the Tennessee Regulatory Authority and previously served as its chairman. She also served in various roles for two Tennessee governors.
An FCC commissioner since 2001 and previously an aide to retired Sen. Ernest Hollings, Copps begins a new five-year term that expires on June 30, 2010.

Unique Interactive Supplies Text Display System to Harris
London and Mason, OH - Dec 19, 2005 - Unique Interactive and Harris have partnered to integrate the Unique Interactive Display Text system into the Harris HD Radio product line. The Unique Interactive Man DLS is an online tool to create, manage and schedule dynamic text for display on HD Radio receivers. In its basic mode, the system links with playout systems for track and artist data, much like RBDS. Advanced modes within Man DLS link the system to information databases for traffic, news and weather, and integrate that data into the existing text stream for live broadcast to an HD Radio receiver. The software also manages sponsor-oriented promotional messages to insert them directly into the broadcast stream from Internet-connected studios. All text-based messages can be scheduled to start and finish within specific time periods.
Man DLS will be rebranded as a Harris product.

Sennheiser Promotes Six
Old Lyme, CT - Dec 20, 2005 - Sennheiser Electronic has further extended its professional products management team by promoting six employees to new positions within the marketing and sales department. The organizational shift focuses on defining responsibilities for professional systems, music industry (MI) and installed sound market segments. To handle overall professional sound and MI, Mark Humrichouser was promoted to the newly created position of industry team manager-professional systems and music industry with Joe Wagoner assuming the newly created counterpart position as industry team leader-installed sound.
Humrichouser joined Sennheiser Electronic in 1997 as market development manager and moved into the position of eastern regional sales manager in 1999. Wagoner started with Sennheiser in 2001 as market development manager-western region and moved to Old Lyme earlier this year to assume the position of product manager-audiology infrared and conferencing systems.
Humrichouser will be responsible for all aspects of marketing and distribution to the professional systems and MI channels, with Wagoner handling the same for installed sound. Both will serve as the pivot point between the factory, Sennheiser's U.S. office and the marketplace regarding product development, distribution strategy, channel communications strategic growth initiatives and promotional campaigns.
Humrichouser and Wagoner will be supported by a product management organization: Chris Phillips will assume the responsibility of product manager-professional systems products and Robb Blumenreder will move into the position of product manager-music industry products. Both report to Humrichouser.
On the installed sound front, Vanessa Jensen assumes the responsibilities of product manager-installed sound with Dennis Zembower in the new position of market development manager tourguide and Guideport systems. Both report to Wagoner.
Wheatstone Updates Generation Software for Mix-minus
New Bern, NC - Dec 21, 2005 - Wheatstone has added mix-minus assignment flexibility in its control surface software created for its Generation line of control surfaces. The latest version of the software now allows the mix-minus bus assignments for a particular source to be saved at set-up and then recalled later when the source is recalled on any control surface channel. Settings for the same source may be different when recalled on different control surfaces in a networked system. The mix-minus assignment functions then effectively follow the source through any routing path, with settings that can vary from studio to studio. The source follow functionality can be disabled to maintain the traditional fader channel based assignments.

CAP matches the audio processing automatically without manual intervention.
Enco’s patent-pending CAP option is available in DAD version 5.0. CAP supports IP-connected Omnia 3, Omnia 5 and Omnia 6 series audio processors.
