FCC Makes Additional Unlicensed Spectrum Available
Washington, DC - Nov 13, 2003 - The FCC has made available an additional 255MHz of spectrum in the 5.470 to 5.725GHz band for unlicensed devices.

In the Report and Order approved on Nov. 12, the Commission made the spectrum available for use by unlicensed National Information Infrastructure (U-NII) devices, including radio local area networks (RLANs), operating under Part 15 of the FCC’s rules. This increases the spectrum available for use by unlicensed devices in the 5GHz region of the spectrum by nearly 80 percent and is a significant increase in the spectrum available for unlicensed devices across the overall radio spectrum. The FCC expects that this action will also harmonize the spectrum available for these U-NII devices throughout the world, enabling manufacturers to reduce product development costs by allowing the same products to be used in many parts of the world.

The new spectrum is part of an effort to enable continued growth and innovation in wireless broadband services, including services offered by wireless Internet service providers (WISPs). WISPs use unlicensed devices to provide a broadband alternative for rural and underserved areas. Although they are a relatively nascent industry, their deployment rates have been increasing rapidly.

In addition to making additional spectrum available for U-NII devices, the Commission also adopted several allocation changes consistent with the results of the 2003 World Radio Conference and an agreement reached with the U.S. Department of Defense, the National Telecommunications and Information Administration (NTIA). These changes will ensure that critical Federal Government operations are protected from harmful interference. In addition to the allocation changes, to provide federal users with additional protection from harmful interference, the order requires that U?NII devices operating in the 5.250 to 5.350GHz and the 5.470 to 5.725GHz bands use dynamic frequency selection (DFS), a listen-before-talk mechanism, and transmit power control (TPC).

Report and Order FCC 03-287, ET Docket No. 03–122.
Radio Stations Must Pay Royalties
Washington – Oct 20, 2003 – The ruling of the U.S. Copyright Office that radio stations must pay such royalties was upheld by the 3rd U.S. Circuit Court of Appeals in Philadelphia. Last year, stations complained that they should not have to pay royalties to performers for their Internet broadcasts because they do not pay them for regular, over-the-air broadcasts.

Historically, radio stations have been required to pay per-song royalties to songwriters but not to performers, recording companies or anyone else who owns the rights to the sound recording of a song.

The NAB’s issued this statement in response to the U.S. Copyright Office’s decision: “"NAB disagrees with the court opinion, which we believe serves to stifle efforts by hometown radio stations to better serve listeners. We will be exploring all of our legal and legislative options to overturn this decision, which we believe misinterprets the intent of Congress."
PPM Response Rates Increasing
New York - Oct 21, 2003 - Arbitron and Nielsen Media Research's tests of methods to improve consumer response rates in the Portable People Meter system produced positive results. In a research test of two sampling and recruitment techniques, response rates among panelists increased significantly over those for prior sampling and recruitment methodologies used for the PPM. Now, additional tests are underway to ensure that these initial success levels can be maintained.
NAB Comments on Mitre Report
Washington - Oct 15, 2003 - The Mitre Corporation was chosen by the FCC to conduct field tests to determine whether LPFM stations would interfere with existing FM stations if LPFM stations were not subject to third adjacent channel spacing requirements.

The NAB states that Mitre’s field test report fails to address two key Congressional mandates: that independent audience listening tests be conducted to establish what is objectionable interference; and that an economic analysis be performed to determine the impact on full power FM stations if third adjacent channel protections were eliminated. The NAB believes that it fails to adhere to clear statutory conditions for any recommendation that third adjacent channel protections be altered.

In a report to the FCC, the NAB states that Mitre's report is "fraught with major technical flaws, including site selection, frequency selection, receiver selection, receiver characterization and testing methodology, so that the resultant test data could in no way support any recommendation regarding the feasibility of relaxing third adjacent channel spacing requirements for LPFM stations.

"Consequently, Mitre’s distance separation formulas will not eliminate third adjacent channel interference and must be rejected out-of-hand. Moreover, MITRE’s spacing formulas are premised on a static population assumption. But population shifts will inevitably occur."

Finally, the NAB states that report actually demonstrates the contrary of its purported conclusion, showing that listeners within a full power FM station’s protected contour will experience harmful interference from LPFM stations located on third adjacent channels. Because of these findings, the NAB is urging the Commission to report to Congress that it cannot recommend the elimination of third adjacent channel protections for LPFM radio service.

Single-Chip Baseband Integrates all Digital Functions
Dallas and Columbia, MD - Oct 8, 2003 - Texas Instruments and Ibiquity have developed a single-chip circuit design to integrate all of the digital functions required to build a combined analog AM/FM and HD Radio receiver. For use in automotive applications, TI's second-generation HD Radio digital baseband, based on TI's programmable digital signal processor (DSP) technology, and a new, complementary intermediate frequency (IF) analog front end (AFE) provide integration including audio processing and MP3 and Windows Media Audio (WMA) CD support.

The DRI250 baseband includes audio processing for sound and WMA and MP3 decoders for automotive CD radio. The integration of digital processing features in a single chip, coupled with TI's analog front end chip, the DRI8201, results in a lower cost of implementation of HD Radio systems. In addition, as a software radio baseband, the DRI250 allows new differentiated features to be added in the future, such as surround sound FM for an enhanced listening experience and time buffering for the ability to rewind live radio. As a software radio, the DRI250 provides manufacturers the flexibility and processing headroom to add support for new standards, features or modifications, as experienced recently with Ibiquity's conversion to its proprietary HDC codec.
FCC Localism Task Force Hearings Begin
Washington - Oct 3, 2003 - The FCC's Localism Task Force will hold six public hearings to solicit input from consumers, industry, civic organizations and others regarding broadcast localism.

    Some of the DAT material that needs to be archived is 48kHz. To do this, a sample rate conversion algorithm provided by Wavelab is used. The data is also normalized internally, then Wavelab’s cue and clip sheets are used for identification purposes.
    2003 Marks 25 Years for Genelec
    New York – Oct 10, 2003 – Based in Iisalmi, Finland, Genelec was founded in 1978 by Iipo Martikainen, Topi Partanen and Ritva Leinonen.

    Moseley Maxlink Gains Acceptance
    Santa Barbara, CA - Oct 20, 2003 – Broadcast engineers are finding that the Maxlink, Moseley’s plug-and-play 5.8GHz bidirectional data link, is making their lives just a little easier. Ralph Brancato, chief engineer at KCLC in St. Louis, uses a Maxlink with a Moseley SL9003T1, T1 STL system to transport two AES digital stereo program channels to his transmitter site, to backhaul a stereo pair to the studio, and provide a interconnection for the facility's transmitter remote control.

    Dave Abdoo, director of engineering at WKBE in Glens Falls, NY, uses a Maxlink with a T1 STL system to transport multiple news channels to the main studio from a remote site elsewhere in the city.

    The Moseley Maxlink is suited for short haul data applications or for STL/TSL when used with the Moseley Starlink T1 system. The Maxlink conveys two T1 or E1 channels in the 5GHz band. Maxlink is easy to deploy, requiring no license and has a range of up to eight miles.
