§  25.111   Additional information.

   (a) The Commission may request from any party at any time additional
   information concerning any application, or any other submission or
   pleading regarding an application, filed under this part.

   (b) Applicants, permittees and licensees of radio stations governed by
   this part shall provide the Commission with all information it requires
   for the Advance Publication, Coordination and Notification of frequency
   assignments pursuant to the international Radio Regulations. No
   protection from interference caused by radio stations authorized by
   other Administrations is guaranteed unless coordination procedures are
   timely completed or, with respect to individual administrations, by
   successfully completing coordination agreements. Any radio station
   authorization for which coordination has not been completed may be
   subject to additional terms and conditions as required to effect
   coordination of the frequency assignments with other Administrations.

   (c) In the Direct Broadcast Satellite service, applicants and licensees
   shall also provide the Commission with all information it requires in
   order to modify the Appendix 30 Broadcasting-Satellite Service (“BSS”)
   Plans and associated Appendix 30A feeder-link Plans, if the system uses
   technical characteristics differing from those specified in the
   Appendix 30 BSS Plans, the Appendix 30A feederlink Plans, Annex 5 to
   Appendix 30 or Annex 3 to Appendix 30A. For such systems, no protection
   from interference caused by radio stations authorized by other
   Administrations is guaranteed until the agreement of all affected
   Administrations is obtained and the frequency assignment becomes a part
   of the appropriate Region 2 BSS and feeder-link Plans. Authorizations
   for which coordination is not completed and/or for which the necessary
   agreements under Appendices 30 and 30A have not been obtained may be
   subject to additional terms and conditions as required to effect
   coordination or obtain the agreement of other Administrations.
   Applicants and licensees shall also provide the Commission with the
   necessary Appendix 4 information required by the ITU Radiocommunication
   Bureau to advance publish, coordinate and notify the frequencies to be
   used for tracking, telemetry and control functions of DBS systems.
