   ^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.

   ^5 But 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.)

   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.

   ^3Within that portion of VHF Public Coast Station Areas (VPCSAs) 1 through 9
   listed in the table in paragraph (c)(1)(ii) of this section within 120 km
   (75 miles) of the United States/Canada border, in the area of the Great
   Lakes, the Saint Lawrence Seaway, and the Puget Sound and the Strait of Juan
   de  Fuca and its approaches, Maritime VHF Channel 88A (157.425 MHz) is
   available for use for public correspondence communications, subject to prior
   coordination  with  Canada.  Maritime VHF Channel 88B (162.025 MHz) is
   available only for Automatic Identification System communications. One
   hundred twenty kilometers (75 miles) from the United States/Canada border
   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.

   ^4Within VHF Public Coast Station Areas (VPCSAs) 1 through 9 listed in the
   table in paragraph (c)(1)(ii) of this section, Maritime VHF Channel 87B
   (161.975  MHz)  may  be  used only for Automatic Identification System
   communications.

   ^5No license authorizing a site-based VHF Public Coast Station or a Private
   Land Mobile Radio Station to operate on maritime VHF Channel 87B (161.975
   MHz) in one of the nine maritime VHF Public Coast Service Areas (VPCSAs)
   listed in the table in paragraph (c)(1)(ii) will be renewed unless the
   license is or has been modified to remove Channel 87B as an authorized
   frequency.

   (ii) Service areas in the marine VHF 156–162 MHz band are VHF Public Coast
   Station 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. Except as shown in the table, the frequency pairs
   listed in paragraph (c)(1)(i) of this section are available for assignment
   to a single licensee in each of the VPCSAs listed in the table in this
   paragraph. 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.

   (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  Sec. 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.

   (3) VPCSA licensees may not operate on Channel 228B (162.0125 MHz), which is
   available for use in the Coast Guard's Ports and Waterways Safety System
   (PAWSS). In addition, VPCSA licensees in VPCSAs 1–9 may not operate on
   Channel  AIS 1 (161.975 MHz) or Channel AIS 2 (162.025 MHz), which are
   designated in those areas exclusively for Automatic Identification Systems
   (AIS), except to transmit and receive AIS communications to the same extent,
   and subject to the same limitations, as other shore stations participating
   in AIS.

   (4) Subject to the requirements of  Sec. 1.924 of this chapter and  Sec. 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  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
