Sec. 80.385 Frequencies for automated systems.
This section describes the carrier frequencies for the Automated Maritime
Telecommunications System (AMTS) and for other automated multi-station
systems.
(a) Automated Maritime Telecommunications System (AMTS). (1) The Automated
Maritime Telecommunications System (AMTS) is an integrated and
interconnected maritime communications system.
(2) The following carrier frequencies are available for assignment to public
coast stations for public correspondence communications with ship stations
and units on land. AMTS operations must not cause harmful interference to
the U.S. Navy SPASUR system which operates in the band 216.880–217.080 MHz.

\1\ Ship transmit frequencies in Groups C and D are not authorized for
AMTS use.
\2\ Coast station operation on frequencies in Groups C and D are not
currently assignable and are shared on a secondary basis with the Low
Power Radio Service in part 95 of this chapter. Frequencies in the
band 216.750-217.000 MHz band are available for low power point-to-
point network control communications by AMTS coast stations under the
Low Power Radio Service (LPRS). LPRS operations are subject to the
conditions that no harmful interference is caused to the United States
Navy's SPASUR radar system (216.88-217.08 MHz) or to TV reception
within the Grade B contour of any TV channel 13 station or within the
68 dBu predicted contour of any low power TV or TV translator station
operating on channel 13.
\3\ Ship transmit frequencies in Groups A and B are permitted to provide
mobile-to-mobile communications where the written consent of all
affected licensees is obtained.
(3) As listed in the table in this paragraph, AMTS Areas (AMTSAs) are based
on, and composed of one or more of, the U.S Department of Commerce's 172
Economic Areas (EAs). See 60 FR 13114 (March 10, 1995). In addition, the
Commission shall treat Puerto Rico, the United States Virgin Islands, and
the Gulf of Mexico as EA-like areas. The Gulf of Mexico EA extends from 12
nautical miles off the United States Gulf coast outward into the Gulf. See
Sec. 27.6(a)(2) of this chapter and 62 FR 9636 . Maps of the EAs and AMTSAs are
available for public inspection and copying at the Federal Communications
Commission, Reference Center, 445 12th Street, SW., Room CY A257,
Washington, DC 20554. These maps and data are also available on the FCC Web
site at www.fcc.gov/oet/info/maps/areas/. The Group A and B frequency pairs
listed in the table in paragraph (a)(2) of this section are available for
assignment to a single licensee in each of the AMTSAs listed in the table in
this paragraph. In addition to the listed EAs listed in the table in this
paragraph, each AMTSA also includes the adjacent waters under the
jurisdiction of the United States.

(4) Channels in the 219–220 MHz band are also used on a secondary,
non-interference basis by amateur stations participating in digital message
forwarding systems. Amateur stations may not cause harmful interference to
AMTS operations and must accept any harmful interference from AMTS
operation. Amateur stations within 80 km (50 miles) of an AMTS coast station
must obtain written approval from the AMTS licensee prior to operating in
the 219–220 MHz band. Amateur stations within 640 km (398 miles) of an AMTS
coast station must notify the AMTS licensee in writing at least 30 days
prior to initiation of operations in the 219–220 MHz band. All amateur
stations must notify the American Radio Relay League in writing at least 30
days prior to initiation of operations in the 219–220 MHz band (ARRL, 225
Main St., Newington, CT 06111–1494).
(b) Subject to the requirements of Sec. 1.924 of this chapter, Sec. Sec. 80.215(h), and
80.475(a), each AMTS geographic area licensee may place stations anywhere
within its region without obtaining prior Commission approval provided:
(1) The AMTS geographic area licensee must locate its stations at least 120
kilometers from the stations of co-channel site-based AMTS licensees.
Shorter separations between such stations will be considered by the
Commission on a case-by-case basis upon submission of a technical analysis
indicating that at least 18 dB protection will be provided to a site-based
licensee's predicted 38 dBu signal level contour. The site-based licensee's
predicted 38 dBu signal level contour shall be calculated using the F(50,
50) field strength chart for Channels 7–13 in Sec. 73.699 (Fig. 10) of this
chapter, with a 9 dB correction for antenna height differential. The 18 dB
protection to the site-based licensee's predicted 38 dBu signal level
contour shall be calculated using the F(50, 10) field strength chart for
Channels 7–13 in Sec. 73.699 (Fig. 10a) of this chapter, with a 9 dB correction
factor for antenna height differential.
(2) The locations and/or technical parameters of the transmitters are such
that individual coordination of the channel assignment(s) with a foreign
administration, under applicable international agreements and rules in this
part, is not required.
(3) For any construction or alteration that would exceed the requirements of
Sec. 17.7 of this chapter, licensees must notify the appropriate Regional Office
of the Federal Aviation Administration (FAA Form 7460–1) and file a request
for antenna height clearance and obstruction marking and lighting
specifications (FCC Form 854) with the FCC, Attn: Information Processing
Branch, 1270 Fairfield Rd., Gettysburg, PA 17325–7245.
(4) The transmitters must not have a significant environmental effect as
defined by Sec. Sec. 1.1301 through 1.1319 of this chapter.
(c) Any recovered frequency blocks will revert automatically to the holder
of the geographic area license within which such frequencies are included.
Any frequency blocks recovered where there is no geographic area licensee
will be retained by the Commission for future licensing.
(d) Automated multi-station system. Great Lakes Region. The following table
describes the assignable carrier frequency pairs to provide communication
services including automated calling, teleprinter and facsimile:
