  • of the rules, to include additional bands approved for international broadcasting use by the World Radio Assembly Conference (WRAC) `92. Third, the staff recommends that the Commission replace the target zone map in section 73.703 of the rules with the current ITU target zone map. Fourth, the staff recommends that the Commission change the frequency control tolerance specified in section 73.756(c) of the rules, to the current ITU regulation standard of 10 Hz. Finally, the staff recommends that the Commission modify the last sentence of section 73.766 of the rules to change the highest modulating frequency from 5 kHz to 4.5 kHz, to reflect a provision in the Final Acts of WARC-87. These changes would bring the Commission's international broadcasting rules

  • in the less developed areas of the world. Accordingly, we tentatively find that footnote S5.134 is currently inadequate to meet the needs of international broadcasters. In order to bring the Commission's Rules for international broadcast stations into conformance with current international provisions, we propose to make the following amendments to Part 73, Subpart F. First, we propose to amend Section 73.756(c) by revising the frequency tolerance of 0.0015 percent of the assigned frequency to the current ITU standard of 10 hertz. We request comment on the number of HFBC stations currently operating that meet the more stringent standard. Further, we request comment on whether it is feasible to modify existing transmitters to meet this standard. If so, what costs are involved?

  • and Alaska private-fixed station use of frequency 11601.5 kHz will be on the condition that harmful interference is not caused to HFBC. In the Notice, the Commission proposed to make amendments to the regulations for international broadcast stations in Part 73, Subpart F of the Commission's Rules to conform to current international provisions. Specifically, the Commission proposed to amend Section 73.756(c) by revising the frequency tolerance of 0.0015 percent of the assigned frequency to the current ITU standard of 10 hertz. It also proposed to revise various HFBC definitions in Section 73.701 of the Rules to reflect international requirements as specified in the 1997 World Radiocommunications Conference (``WRC-97'') Final Acts. Specifically, the Commission proposed in the Notice to revise definitions for

  • the HFBC bands. Specifically, so that there is no ambiguity regarding the rules with which HF broadcasters must comply, we propose to add to our rules the ITU requirements for DSB, SSB, and digital HFBC systems, which are listed in revised Appendix 11 of the ITU Radio Regulations. The specific language of our proposal is presented in Appendix A, Section 73.756. The effect of these proposals would be to grant U.S.-licensed international broadcast stations the flexibility to continue to transmit analog DSB signals or to transmit SSB or digital signals, including DRM signals (currently the only ITU-recommended digital standard for use in HFBC bands), which would allow international broadcast stations to provide FM-like sound quality to listeners in foreign countries. Nonetheless,

NASB states that it agrees with all of the proposals relating to HF broadcasting, except for the minimum power level for digital transmissions. Specifically, NASB agrees with the system specifications for DSB, SSB, and digital transmissions as indicated in the proposed revision of Section 73.756. NASB does not agree that a mean power of 20 kW for digital transmissions is necessary in order to provide approximately the same coverage as a 50-kW analog transmission. Instead, NASB requests that the Commission adopt a lower minimum power level. NASB emphasizes that in order for digital transmissions to co-exist along with DSB and SSB transmissions in the same
