FCC Issues NPRM on AM Use of FM Translators
Washington - Aug 15, 2007 - On July 14, 2006, the National Association of Broadcasters filed a petition for rulemaking proposing an amendment to the FCC Rules to allow AM broadcast stations to operate FM translator stations. The NAB Petition proposed that AM stations be permitted to license and/or use FM translator stations to retransmit their AM service as a fill-in service to rebroadcast the AM signal, provided that no portion of the 60dBu contour of any such FM translator station extends beyond the smaller of a 25-mile radius from the AM transmitter site, or the 2mV/m daytime contour of the AM station. The FCC received more than 500 comments on the NAB petition, with the majority supporting the proposal.

The FCC has issued a notice of proposed rule making (NPRM) to enact rules to permit the use of FM translators by AM stations. The FCC will also examine the issues related to such a rule change, including the issue of program origination at night over FM translators by AM daytime-only stations.

Comments are due 60 days after the public notice appears in the Federal Register. Reply comments are due 90 days after publication of the notice in the Federal Register.
MB Docket No. 07-172

IBOC Rules Published in Federal Register
Washington - Aug 15, 2007 - The FCC's final rules on IBOC have been published in the Federal Register. With this publication, the details of the second report and order from May 2007 will go into effect. There are three items in those rules that now have time lines. These all take effect on Sept. 14, 2007:

  • AM stations can commence night-time IBOC operations.
  • FM stations can multicast without obtaining special temporary authority from the FCC.
  • FM stations can use separate antennas for hybrid IBOC operation without obtaining special temporary authority from the FCC.

The FCC is still seeking some comments on various aspects, and Mexico has recently made some protests about IBOC, so more information will likely be released by the FCC at a later time.

The complete final rules are available at this link.

FCC Considers NCE FM Application Cap for October Filing Window
Washington - Aug 9, 2007 - On April 4, 2007, the Federal Communications Commission announced a filing window from Oct. 12, 2007 until Oct. 19, 2007, for FM reserved-band applications for noncommercial educational (NCE) FM new station and major change applications. At that time, the FCC reserved the right to establish a limit on the number of NCE applications allowed by a single party.

After the NCE FM filing window was announced, several parties involved in NCE FM station operations filed proposals to limit the number of NCE FM applications that any party may file during the filing window. The proposals uniformly express concern that failure to establish a limit on the number of NCE FM applications from a single party would lead to a large number of speculative filings, creating the potential for extraordinary procedural delays. The FCC agrees to the likelihood of this possibility.

The FCC proposes that an applicant may hold no more than 10 applications filed in the window. If the FCC finds that an applicant has an interest in more than 10 applications, the FCC will retain the 10 applications filed first and dismiss all other applications. Major modification applications will not count toward the limit. Pending new and major change applications filed under former licensing procedures also will not count toward the limit.

The FCC seeks comments on this proposed limit. Comments are due 15 days after date of publication in the Federal Register, and reply comments are due 25 days after date of publication in the Federal Register. All filings must be submitted in MM Docket No. 95-31.

Harris Presents Digital Radio Technology at Dominican Republic Radio Event
Cincinnati - Aug 14, 2007 - Harris showcased its digital radio technology at the Digital Radio Forum in the Dominican Republic. Harris teamed with its Dominican Republic dealer, Repuestos de Radio and TV, to provide presentations for regional broadcasters interested in digital radio.

The forum, which was planned by Indotel, the Dominican Republic's equivalent of the FCC, showed radio transmission technology and implementation strategies for all three standards.

The Harris exhibition included the Flexstar HDX exciter operating in hybrid mode with a Harris Z-Series tri-mode transmitter. The company showed examples of how stations are using HD Radio to multicast in the U.S., and provided a formal presentation on the three digital standards: HD Radio, DRM and DAB.

Representatives of numerous islands, including Bermuda and the Bahamas, attended the event. It was noted that some broadcasters in Puerto Rico are currently transmitting an HD Radio signal, and because of this, many Caribbean nations seem to be leaning toward HD Radio broadcasting.

While HD Radio was the focus of most discussion, Caribbean broadcasters also expressed interest in DRM and DAB. Broadcasters from Europe were on hand to discuss successes with these standards.
