describes the working carrier frequency pairs in the 2000-4000 kHz
band.

^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.)

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

^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.
