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

    (a) AMTS applicants proposing to serve inland waterways must show 
how the proposed system will provide continuity of service along more 
than 60% of each of one or more navigable inland waterways. Inland 
waterways less than 240 kilometers (150 miles) long must be served in 
their entirety. AMTS applicants proposing to serve portions of the 
Atlantic, Pacific or Gulf of Mexico coastline must define a substantial 
navigational area and show how the proposed system will provide 
continuity of service for it. A separate Form 503 is not required for 
each coast station in a system. However, 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 television station or 
within 129 kilometers (80 miles) of a channel 10 television 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 
Sec. 80.215(h).

    (2) Additionally, applicants required to submit the above specified 
must give written notice of the filing of such application(s) to the 
television stations which may be affected. A list of the notified 
television stations must be submitted with the subject applications.
    (b) In lieu of public correspondence service an AMTS system may 
provide private coast station communications related to the operational 
requirements of ships including transmissions of fuel, weather, position 
and supply reports. However, such communications may be provided only to 
ship stations whose licensees make cooperative arrangements with the 
AMTS coast station licensees. In emergency and distress situations, 
services must be provided without prior arrangements.
