 Re: Application of L3 Communications,Interstate Electronies Corporation (IEC)
      Call Sign: E020160
      FCC File Number SES—LIC—20020611—00939
 Interstate Electronies Corporation (IEC), a division ofL—3 Communications has an earth station
 application pending before the U.S. Federal Communications Commission (FCC). 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,
