§  80.475   Scope of service of the Automated Maritime Telecommunications
System (AMTS).

   (a) A separate Form 601 is not required for each coast station in a
   system. However, except as provided in § 80.385(b) and paragraph (b) of
   this section, the applicant must provide the technical characteristics
   for each proposed coast station, including transmitter type, operating
   frequencies, emissions, transmitter output power, antenna arrangement,
   and location.

   (1) Applicants proposing to locate a coast station transmitter within
   169 kilometers (105 miles) of a channel 13 TV station or within 129
   kilometers (80 miles) of a channel 10 TV station or with an antenna
   height greater than 61 meters (200 feet), must submit an engineering
   study clearly showing the means of avoiding interference with
   television reception within the grade B contour, see § 80.215(h) of
   this chapter, unless the proposed station's predicted interference
   contour is fully encompassed by the composite interference contour of
   the applicant's existing system, or the proposed station's predicted
   interference contour extends the system's composite interference
   contour over water only (disregarding uninhabited islands).

   (2) Additionally, applicants required to submit the above specified
   must give written notice of the filing of such applications(s) to the
   television stations which may be affected. A list of the notified
   television stations must be submitted with the subject applications.

   (b) Coast stations for which the above specified need not be submitted
   because the proposed station's predicted interference contour is fully
   encompassed by the composite interference contour of the applicant's
   existing system or the proposed station's predicted interference
   contour extends the system's composite interference contour over water
   only (disregarding uninhabited islands) must, at least 15 days before
   the station is put into operation, give written notice to the
   television stations which may be affected of the proposed station's
   technical characteristics, the date it will be put into operation, and
   the licensee's representative (name and phone number) to contact in the
   event a television station experiences interference. No prior FCC
   authorization is required to construct and operate such a station, but,
   at the time the station is added, the AMTS licensee must make a record
   of the technical and administrative information concerning the station
   and, upon request, supply such information to the FCC. In addition,
   when the station is added, the AMTS licensee must send notification of
   the station's location to the American Radio Relay League, Inc., 225
   Main Street, Newington, CT 06111-1494, and Interactive Systems, Inc.,
   Suite 1103, 1601 North Kent Street, Arlington, VA 22209.

   (c) An AMTS system may provide private mobile radio service in addition
   to or instead of public correspondence service. However, such
   communications may be provided only to stations whose licensees make
   cooperative arrangements with the AMTS coast station licensees. In
   emergency and distress situations, services must be provided to ship
   stations without prior arrangements.

   (d) AMTS systems providing private mobile radio service instead of, or
   in addition to, public correspondence service are not required to be
   interconnected to the public switched network when providing such
   private mobile radio service. AMTS systems providing public
   correspondence service must be interconnected to the public switched
   network, but the licensee may also offer non-interconnected services.
