Protection of Radio Astronomy ATC operators are subject to technical and procedural requirements prescribed in Sections 1.924 and 25.203(e)-(g) of the Commission's rules for interference protection for FCC monitoring stations and radio-astronomy observation at sites in West Virginia, Colorado, and Puerto Rico. GLLC declares that it will comply with these requirements.

In Paragraph 75 of the Report and Order, the Commission said that it was adopting a suggestion to include a note in Section 25.216 of the Commission's rules cross-referencing Sections 25.202(f) and 25.213(a)(1). Instead of referring to Section 25.213(a)(1), however, the corresponding note in the rule-change appendix erroneously mentions Section 25.143(a). We are therefore amending the note to Section 25.216 to read as follows: NOTE: Operation of mobile earth stations is also subject to all pertinent emission limits specified in other sections of the Commission's Rules. See Sections 25.202(f) and 25.213(a)(1). FEDERAL COMMUNICATIONS

Adoption of an immediately-effective wideband limit of -70 dBW/MHz on the spectral power density of out-of-band emissions between 1559 and 1580.42 MHz, as the NTIA recommends and as we are proposing, would be consistent with the ITU-R and ETSI standards. As we have noted, moreover, Section 25.213(b) of the Commission's rules already prescribes a -70 dBW/MHz limit for suppression of emissions in the core GPS band, i.e., 1574.397-1576.443 MHz. Constellation Communications, Inc., a Big LEO licensee, raises an objection, however, based on its understanding of the history of Section 25.213(b).
