FCC Okays Use of SeparateAntennas for IBOC
Washington - Mar 17, 2004 - On Oct. 10, 2002, the FCC authorized interim operation with the Ibiquity hybrid IBOC systems. Under these interim authorization procedures, stations can only use facilities similar to those evaluated by the National Radio Systems Committee. In particular, FM stations are restricted to transmission systems that combine the digital and analog signals into one antenna. On July 24, 2003, the NAB submitted a report to the Commission regarding the use of separate antennas for the analog and digital components of the hybrid FM IBOC signal. The report included field tests prepared by an ad hoc technical group, and recommended that the Commission permit certain FM stations implementing IBOC transmissions to use separate antennas for analog and digital signals, provided that the following criteria are met:
The digital transmission must use a licensed auxiliary antenna.
The auxiliary antenna must be within three seconds of latitude and longitude of the main antenna.
The height above average terrain of the auxiliary antennas must be between 70 percent and 100 percent of the height above average terrain of the main antenna.
In a Public Notice released Dec. 8, 2003, the Commission sought comment on the conclusions and recommendations made by the NAB report. Comments were due by Jan. 8, 2004, and reply comments were due by Jan. 23, 2004.
Several commenters suggested broadening the NAB recommendations to include dual-antenna systems at variance with the NAB recommendations; however, in the interest of expediting the initiation of dual antenna operation for systems that meet the recommended criteria, the FCC has defered consideration of such systems to a future Further Notice of Proposed Rule Making.
The FCC believes that the pubic interest would be served by permitting dual-antenna FM IBOC implementation at this time. Although the NAB report recommended expanding the notification procedures currently in place for combined antenna implementation, such operation does not fall within the scope of the notification procedures authorized by the IBOC order, and thus will require separate action by the Commission.
Consequently, in the interest of expediency, the FCC has authorized conforming dual antenna FM IBOC transmissions pursuant to routine special temporary authorization (STA) procedures. The matter of expanded notification procedures will be deferred for consideration at a future date. The NAB report also recommends that the Commission authorize use of antennas specially designed with interleaved or stacked elements for analog and digital signals. Because such antennas clearly meet the horizontal and vertical distance criteria, the use of such antennas will be considered acceptable, provided that the interleaved antenna system is first licensed as an auxiliary antenna.
We note that a debate has arisen recently in various technical fora as to the proper designation of these dual-feed systems, in which the digital and analog signals are introduced to the same set of active antenna elements through different input connections. Based on the information currently available to the FCC, if the digital and analog signals are fed to the same set of active, radiating elements, that system is a combined system. Licensees may obtain authority to operate this kind of system in accordance with the notification procedures set forth in the IBOC order. Where different sets of active, radiating elements are used for the analog and digital signals, the system will be considered as a separate-antenna system, and subject to the STA procedures announced in the FCC's public notice.
FM stations may file requests for STA to commence IBOC operations using dual-antenna systems that meet the NAB recommended criteria.
The FCC noted that stations implementing IBOC shall broadcast the same main channel program material in analog and digital modes.

House Passes Broadcast DecencyEnforcement Act
Washington - Mar 11, 2004 - The House of Representatives approved
the Broadcast Decency Enforcement Act of 2004 by a vote of 391 to 22.
This act, which modifies the Communications Act of 1934, increase the
maximum fine for radio and TV indecency. The bill would raise the
maximum fine for a broadcast license holder from $27,500 to $500,000.
The fine for a performer would also increase from $11,000 to
Decency has been a hot topic in the news lately, and opponents of the legislation feel that this action undermines free-speech rights. Clear Channel has already announced it will require its air talent to pay part of any indecency fines. AFTRA has opposed the Clear Channel move saying that the station licensees are responsible and that performers are following owners' mandates.
The Senate has a bill that will also raise fines to $500,000. On March 9, the Senate Commerce Committee unanimously passed a bill to increase fines for broadcast indecency violations. The measure is listed as S. 2056. The Senate bill includes wording to direct the FCC to conduct a mandatory license revocation hearing after three indecency violations.
The House bill is listed as H.R. 3717.
Broadcast Electronics and E-radioAnnounce Partnership
Quincy, IL, and Toronto – Mar 18, 2004 - Broadcast Electronics
and E-radio have entered into a partnership to develop RBDS and IBOC
data applications. The applications will transmit a variety of
additional information on display screens such as song titles, artist
names, traffic updates, weather forecasts and sports scores. The
partnership joins Broadcast Electronics' experience in RF and content
management with E-Radio's text service and media delivery
The result of the companies' efforts is Broadcast Electronics' Radio Data Dimensions, a data management software suite to be unveiled at the NAB2004 convention. In addition to RBDS eight-character identifiers and 64-character text of title/artists, promotional messages, advertiser IDs, traffic bulletins and AMBER alerts, the software suite includes support for IBOC's secondary program channel services such as Tomorrow Radio. Radio Data Dimensions also provides bandwidth provisions for navigational system data downloads to tuners. All functions and user controls for the software suite are accessible from a Web-browser content management tool.
Shively Supplies Systems for MiddleEast
Bridgeton, ME - Mar 15, 2004 - Shively Labs has shipped eight
multi-station and combiner systems to Iraq for the International
Broadcasting Bureau/Broadcasting Board of Governors. The IBB will use
Shively equipment to broadcast from more than 14 sites in Iraq. The
systems include fixed frequency, broadband and adjustable frequency
antennas, as well as adjustable bandpass filters.
These combined systems will carry the programming of Voice of America and Radio Sawa.
Shively experience in building equipment for extreme-weather broadcast sites and the skills of Shively's parent company, Howell Laboratories, in packaging electronic equipment to survive military shock and vibration requirements were important aspects of this project.
The Iraq orders are part of an on-going, multi-year contract between Shively Labs and the IBB for FM broadcast equipment as the U.S. Government broadcaster increases its presence on the FM airwaves around the world. The IBB is an agency of the State Department and the successor to Voice of America. Additional projects have recently been completed for Qatar, Bahrain, Kuwait, Jordan, and Georgia. Products range from low power, fixed frequency sidemount antennas to a twelve bay, broadband directional panel system.
WDRQ-FM and Telenor Deal on TextMessaging
Rockville, MD, and Detroit - Mar 9, 2004 - WDRQ-FM, licensed to ABC

Arbitron Inks Deal withMediaguide
New York and Berwyn, PA - Mar 9, 2004 - Arbitron is enhancing its
Radar network radio ratings service through an agreement with
Mediaguide, a technology-based media and marketing information company
that monitors more than 2,300 local market radio and TV stations
