EC plans to use this Ku Band system to communicate with Intelsat Americas 5 (LA—5), which is located at 97 degrees west longitude. Your company operates the Nimig 1, located at 91.00 degrees west longitude. As your satellite is within 6 degrees of IA—5, the FCC requires we obtain an affidavit from you on our proposed system. ‘You have the right to replyto the enclosed material and may reply directly to the FCC, citing the above file number. Ifyou do not reply within thirty(30) calendar days from the date ofthis notice, the FCC will construe your lack ofreply as an assent tothe grant of IEC‘s earth station application. Sincerely, k cc.
