Sec.  74.949   Individually licensed 125 kHz channel ITFS response stations.

   

   (a) The provisions of Sec. 74.939(a), (e), (h), (j), (k), (n) and (o)
   shall also apply with respect to the authorization of 125 kHz channel
   ITFS response stations not authorized under a response station hub
   license. The applicant shall also comply with the requirements of
   Sec. 74.903 and Sec. 21.938 of this chapter where appropriate, as well as with
   the provisions of Sec. Sec. 21.909 and 21.913 of this chapter and of Sec. Sec. 74.939
   and 74.985 regarding the protection of response station hubs and
   booster (and primary) service areas from harmful electromagnetic
   interference, using the appropriately adjusted interference protection
   values based upon the ratios of the bandwidths involved.

   (b) An application for a license to operate a new or modified 125 kHz
   channel ITFS response station not under a response station hub license
   shall be filed with the Commission in Washington, D.C., on FCC Form
   331. The applicant shall supply the following information and
   certification on that form for each response station:

   (1) The geographic coordinates and street address of the ITFS response
   station transmitting antenna; and

   (2) The manufacturer's name, type number, operating frequency, and
   power output of the proposed ITFS response station transmitter; and

   (3) The type of transmitting antenna, power gain, azimuthal
   orientation and polarization of the major lobe of radiation in degrees
   measured clockwise from True North; and

   (4) A sketch giving pertinent details of the ITFS response station
   transmitting antenna installation including ground elevation of the
   transmitter site above mean sea level; overall height above ground,
   including appurtenances, of any ground-mounted tower or mast on which
   the transmitting antenna will be mounted or, if the tower or mast is
   or will be located on an existing building or other manmade structure,
   the separate heights above ground of the building and the tower or
   mast including appurtenances; the location of the tower or mast on the
   building; the location of the transmitting antenna on the tower or
   mast; and the overall height of the transmitting antenna above ground.

   (5) A certification that all licensees and applicants appropriately
   covered under the provisions of paragraph (a) of this section have
   been served with copies of the application.

   (c) Each ITFS response station licensed under this section shall
   comply with the following:

   (1) No ITFS response station shall be located beyond the protected
   service area of the ITFS station with which it communicates; and

   (2) No ITFS response station shall operate with a transmitter output
   power in excess of 2 watts; and

   (3) No ITFS response station shall operate at an excess of 16 dBW
   EIRP.

   (d) During breaks in communications, the unmodulated carrier frequency
   shall be maintained within 35 kHz of the assigned frequency at all
   times. Adequate means shall be provided to insure compliance with this
   rule.

   (e) Each ITFS response station shall employ a directive transmitting
   antenna oriented towards the transmitter site of the associated ITFS
   station or towards the response station hub with which the ITFS
   response station communicates. The beamwidth between half power points
   shall not exceed 15° and radiation in any minor lobe of the antenna
   radiation pattern shall be at least 20 dB below the power in the main
   lobe of radiation.

   (f) A response station may be operated unattended. The overall
   performance of the response station transmitter shall be checked by
   the licensee of the station or hub receiving the response signal, or
   by the licensee's employees or agents, as often as necessary to ensure
   that the transmitter is functioning in accordance with the
   requirements of the Commission's rules. The licensee of the station or
   hub receiving the response signal is responsible for the proper
   operation of the response station and must have reasonable and timely
   access to the response station transmitter. The response station shall
   be installed and maintained by the licensee of the associated station
   or hub, or the licensee's employees or agents, and protected in such
   manner as to prevent tampering or operation by unauthorized persons.
   No response station which has not been installed by an authorized
   person may lawfully communicate with any station or hub.
