Sec.  25.274   Procedures to be followed in the event of harmful interference.

   (a) The earth station operator whose transmission is suffering harmful
   interference shall first check the earth station equipment to ensure that
   the equipment is functioning properly.

   (b) The earth station operator shall then check all other earth stations in
   the licensee's network that could be causing the harmful interference to
   ensure that none of the licensee's earth stations are the source of the
   interference and to verify that the source of interference is not from a
   local terrestrial source.

   (c) After the earth station operator has determined that the source of the
   interference is not another earth station operating in the same network or
   from a terrestrial source, the earth station operator shall contact the
   satellite system control center and advise the satellite operator of the
   problem. The control center operator shall observe the interference incident
   and make reasonable efforts to determine the source of the problem. A record
   shall be maintained by the control center operator and the earth station
   operator of all harmful interference incidents and their resolution. These
   records shall be made available to an FCC representative on request.

   (d) Where the suspected source of the interference incident is the operation
   of an earth station licensed to operate on one or more of the satellites in
   the satellite operator's system, the control center operator shall advise
   the offending earth station of the harmful interference incident and assist
   in the resolution of the problem where reasonably possible.

   (e) The earth station licensee whose operations are suspected of causing
   harmful interference to the operations of another earth station shall take
   reasonable measures to determine whether its operations are the source of
   the harmful interference problem. Where the operations of the suspect earth
   station are the source of the interference, the licensee of that earth
   station shall take all measures necessary to resolve the interference.

   (f) Where the earth station suspected of causing harmful interference to the
   operations of another earth station cannot be identified or is identified as
   an earth station operating on a satellite system other than the one on which
   the earth station suffering harmful interference is operating, it is the
   responsibility of a representative of the earth station suffering harmful
   interference to contact the control center of other satellite systems. The
   operator of the earth station suffering harmful interference is free to
   choose any representative to make this contact, including but not limited to
   the operator of the satellite system on which the earth station is
   operating. The operator of the earth station suffering harmful interference
   is also free to contact the control center of the other satellite systems
   directly.

   (g) At any point, the system control center operator may contact the
   Commission's Columbia Operations Center in Columbia, Maryland, to assist in
   resolving the matter. This office specializes in the resolution of satellite
   interference problems. All licensees are required to cooperate fully with
   the Commission in any investigation of interference problems.
