This section describes the radiotelephony working frequencies assignable to
ship and public coast stations.

^1Unlimited hours of use from December 15 to April 1 and day only from April
1 to December 15. Harmful interference must not be caused to any station in
the Great Lakes region.
^2In the Great Lakes region 2206 kHz is not available for transmission to
U.S. ships except in the case of distress. U.S. coast stations in the Great
Lakes area may use 2514, 2550 and 2582 kHz on a shared basis with coast
stations of Canada. Except in the case of distress, the frequency 2550 kHz
must not be used for transmission to ship stations of Canada since the
associated ship station transmit frequency 2158 kHz is not available to
Canadian ship stations for transmission and 2582 kHz must not be used for
public correspondence transmissions to U.S. ship stations since the
associated ship transmit frequency 2206 kHz is not available to U.S. ship
stations for transmissions except in the case of distress.
^3Limited to a peak envelope power of 150 watts.
^4Harmful interference must not be caused to any coast station in the
Caribbean region.
^5But see section 80.373(c)(3) of this chapter.
(b) Working frequencies in the 4000-27500 kHz band. This paragraph describes
the working carrier frequencies in the 4000-27500 kHz band. With respect to
frequencies that are assignable in more than one geographical area, once the
frequency is assigned to one licensee, any subsequent license will be
authorized on a secondary, non-interference basis with respect to the
incumbent license's existing operation. If the first licensee later seeks
authorization to operate in an additional geographic area, such
authorization will be on a secondary, non-interference basis to other
co-channel licensees.
(1) The following table specifies the carrier frequencies available for
assignment to public coast stations. The paired ship frequencies are
available for use by authorized ship stations. The specific frequency
assignment available to public coast stations for a particular geographic
area is indicated by an “x” under the appropriate column. The allotment
areas are in accordance with the “Standard Defined Areas” as identified in
the International Radio Regulations, Appendix 25 Planning System, and
indicated in the preface to the International Frequency List (IFL).

(2) The following table specifies the non-paired carrier frequencies that
are available for assignment to public coast stations for simplex
operations. These frequencies are available for use by authorized ship
stations for transmissions to coast stations (simplex operations).
Assignments on these frequencies must accept interference. They are shared
with government users and are considered “common use” frequencies under the
international Radio Regulations. They cannot be notified for inclusion in
the Master International Frequency Register, which provides stations with
interference protection, but may be listed in the international List of
Coast Stations. (See Radio Regulation No. 1220 and Recommendation 304.)

and coast stations for calling on a simplex basis, provided that the peak
envelope power does not exceed 1 kW.
(c) Working frequencies in the marine VHF 156-162 MHz band. (1)(i) The
frequency pairs listed in this paragraph are available for assignment to
public coast stations for communications with ship stations and units on
land.

^1For special assignment of frequencies in this band in certain areas of
Washington State, the Great Lakes and the east coast of the United States
pursuant to arrangements between the United States and Canada, see subpart B
of this part.
^2The frequency pair 157.275/161.875 MHz is available on a primary basis to
ship and public coast stations. In Alaska it is also available on a
secondary basis to private mobile repeater stations.
^3 The frequency 161.975 MHz is available only for Automatic Identification
System communications. In VPCSAs 10-42, site-based stations licensed to
operate on frequency 161.975 MHz prior to March 2, 2009 may continue to
operate on a co-primary basis on that frequency until March 2, 2024.
^4The frequency 162.025 MHz is available only for Automatic Identification
System communications. One hundred twenty kilometers (75 miles) from the
United States/Canada border, the frequency 157.425 MHz is available for
intership and commercial communications. Outside the Puget Sound area and
its approaches and the Great Lakes, 157.425 MHz is available for
communications between commercial fishing vessels and associated aircraft
while engaged in commercial fishing activities.
^5In VPCSAs 10-42, the working carrier frequency pair 157.250/161.850 MHz
(Channel 25) is not available for assignment under part 80.
(ii) Service areas in the marine VHF 156-162 MHz band are VHF Public Coast
Service Areas (VPCSAs). As listed in the table in this paragraph, VPCSAs 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 Guam and the Northern Mariana Islands, Puerto Rico
and the United States Virgin Islands, American Samoa, and the Gulf of Mexico
as EA-like areas, and has assigned them EA numbers 173-176, respectively.
Maps of the EAs and VPCSAs are available for public inspection and copying
at the FCC Public Reference Room, Room CY-A257, 445 12th Street, SW.,
Washington, DC 20554, 1-888-225-5322. In addition to the EAs listed in the
table in this paragraph, each VPCSA also includes the adjacent waters under
the jurisdiction of the United States. In VPCSAs 10-42, the working carrier
frequency pair 157.250 MHz/161.850 MHz (Channel 25) is not available for
assignment under part 80.

(iii) Subject to paragraph (c)(3) of this section, each licensee may also
operate on 12.5 kHz offset frequencies in areas where the licensee is
authorized on both frequencies adjacent to the offset frequency, and in
areas where the licensee on the other side of the offset frequency consents
to the licensee's use of the adjacent offset frequency. Coordination with
Canada is required for offset operations under any circumstance in which
operations on either adjoining 25 kHz channel would require such
coordination. See § 80.57 of this part.
(2) Any recovered channel pairs will revert automatically to the holder of
the VPCSA license within which such channels are included, except the
channel pairs listed in the table in paragraph (c)(1)(i) of this section.
Those channel pairs, and any channel pairs recovered where there is no VPCSA
licensee, will be retained by the Commission for future licensing.
(e) Canada/U.S.A. channeling arrangement frequencies. The VHF frequencies
assignable to ship and coast stations in the State of Washington and their
usage limitations pursuant to the Canada/U.S.A. channeling arrangement are
described in subpart B of this part.
(4) Subject to the requirements of § 1.924 of this chapter and § 80.21, each
VPCSA licensee may place stations anywhere within its region without
obtaining prior Commission approval provided:
(i) It provides to co-channel coast station incumbent licensees, and
incumbent Private Land Mobile Radio licensees authorized under part 90 of
this chapter on a primary basis, protection as defined in subpart P of this
part. VPCSA licensees that share a common border may either distribute the
available frequencies upon mutual agreement or request that the Commission
assign frequencies along the common border.
(ii) 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.
(iii) For any construction or alteration that would exceed the requirements
of § 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.
(iv) The transmitters must not have a significant environmental effect as
defined by § § 1.1301 through 1.1319 of this chapter.
(d) Working frequencies in the Mississippi River System. The Mississippi
River System includes the Mississippi River and connecting navigable waters
other than the Great Lakes. The following simplex frequencies are available
for assignment to public coast stations serving the Mississippi River System
for radiotelephony communications. These simplex frequencies also are
available for use by authorized ship stations within communication service
range, whether or not the ship is operating within the confines of the
Mississippi River System.
