Sec.  80.373   Private communications frequencies.

   This section describes the carrier frequencies assignable for ship-to-ship
   and ship-to-coast private communications.

   (a) Special requirements for private coast stations. Assignment to private
   coast stations of radiotelephony frequencies in the 2000–27500 kHz band are
   subject to the following:

   (1) Private coast stations must use J3E emission.

   (2) On 2182 kHz, private coast stations must be capable of receiving J3E and
   H3E emissions.

   (3) Except in the Mississippi River System and Great Lakes, private coast
   stations serving lakes or rivers are not authorized on the 2000–2850 kHz
   band.

   (4)  Private  coast stations may use DSC for calling on their assigned
   frequencies in the 2000–27500 kHz band and on those frequencies in the
   156–162 MHz band which are allocated for maritime control, commercial and
   non-commercial communications.

   (b) Frequencies in the 2000–27500 kHz band for intership safety and other
   communications. This paragraph describes the geographic areas of operation
   and the frequencies and liminations in the band available for assignment for
   intership safety and operational simplex radiotelephone communications.

   (1) Frequencies avaiable. 
   Carrier frequency (kHz) Geographic area
   2003.0 Great Lakes only.
   2082.5^1,2 All areas.
   2093.0^1 All areas.
   2142.0 Pacific coast areas south of 42 degrees north on a day basis only.
   2203.0^2 Gulf of Mexico.
   2214.0^1 All areas.
   2638.0^1 All areas.
   2670.0 All areas.
   2738.0^1 All areas except the Great Lakes.
   2830.0 Gulf of Mexico only.

   ^1Limited to a peak envelope power of 150 watts.

   ^2Available on a secondary basis for intership communications by ships
   involved in non-commercial fishing.

   (2) Except for 2093.0 kHz and 2214.0 kHz the frequencies shown in paragraph
   (b)(1)  of  this section are authorized primarily for intership safety
   communications in the indicated geographic area.

   (3) Except for the frequencies 2093.0 kHz, 2214.0 Khz and 2670.0 kHz the
   frequencies shown in paragraph (b)(1) of this section may be used on a
   non-interference  basis  to  safety  communications,  for  operational
   communications and in the case of commercial transport ships and ships of
   municipal and state governments, for business communications.

   (4) Ship stations may communicate with government coast stations on 2003.0
   kHz  about  passage  of  vessels.  Interference  must not be caused to
   communications on the St. Lawrence Seaway and on the St. Mary's River.

   (5) Ship stations may use 2670.0 kHz for communications with coast and ship
   stations of the U.S. Coast Guard. When a ship is not equipped to transmit on
   2670.0 kHz or in the band 156–162 MHz the frequency 2003.0 kHz may be used
   on the Great Lakes for communications must not cause harmful interference to
   intership safety, operational and business communications.

   (6) Navigational communications between ships and private coast stations may
   be exchanged on 2738.0 kHz and 2830.0 kHz. The frequencies 2214.0 kHz2738.0
   kHz and 2830.0 kHz are assignable to private coast stations upon a showing
   that they need to communicate with commercial transport or Government ships.
   Private coast station applicants must show that public coast stations do not
   provide the required communications and harmful interference will not be
   caused to the intership use of these frequencies. The transmitter power must
   not exceed 150 watts. If 2214.0 kHz is authorized for ships, intership
   communication  is  also  authorized. The geographic limitations to the
   frequencies  2738.0  KHz  and  2830.0  Khz  do  not prohibit intership
   communication of less than 320 km (200 statute miles) when only one of the
   ship stations is within a permitted use geographic area.

   (7) Private aircraft stations may communicate with ship stations on 2738.0
   kHz and 2830.0 kHz if:

   (i) The communications are limited to business or operational needs of the
   vessel while it is engaged in commercial fishing activities in the open sea
   or adjacent waters;

   (ii) Harmful interference must not be caused to intership communications;

   (iii) The maximum output power used for such communication must not exceed
   25 watts;

   (c) Frequencies in the 2000–27500 kHz bands for business and operational
   communications. (1) The following simplex frequencies in the 2000–27500 kHz
   band are available for assignment to private coast stations for business and
   operational radiotelephone communications. These simplex frequencies also
   are  available  for  use  by authorized ship stations for business and
   operational radiotelephone communications.

   including communications with any scene-of-action aircraft.

   ^5The frequency 6516 kHz is limited to daytime operations. The frequencies
   4417  kHz  and  6516 kHz are also available for calling and reply, see
    Sec. 80.369(d) of this part.

   ^6The alternative carrier frequency 12359 kHz may be used by ship stations
   and coast stations for calling on a simplex basis, provided that the peak
   envelope power does not exceed 1 kW.

   (2) Assignment of these frequencies is subject to the following general
   limitations:

   (i) These frequencies are shared and are not available for the exclusive use
   of any station. No more than one frequency from each of the frequency bands
   will be authorized to a private station without justification;

   (ii) The emissions must be J3E or J2D except that when DSC is used the
   emission must be F1B or J2B; and

   (iii) Maximum transmitter output power is limited to 1 kW except as noted.

   (3)  In  addition to the frequencies shown in paragraph (c)(1) of this
   section, the following coast transmit frequencies listed in the table in
    Sec. 80.371(a) of this chapter are available for assignment to private coast
   stations and authorized ship stations for simplex business and operational
   radiotelephone communications: in the East Coast, West Coast, and Gulf Coast
   regions, 2482 kHz; in the Alaska region, 2309 kHz. These frequencies shall
   not be assigned to public coast stations before July 25, 2002. After that
   date,  only  the above frequencies in the above regions that have been
   assigned  to  at  least one private coast station shall continue to be
   available for assignment to private coast stations. If, by that date, in any
   of the above regions, any of the above frequencies has not been assigned to
   a private coast station, that frequency in that region shall be available
   for assignment only to public coast stations.

   (d) Radioprinter frequencies. (1) The following table describes the bands
   available for radioprinter simplex communications between ship and private
   coast stations:

   the Great Lakes for transmission of scheduled Coded Marine Weather Forecasts
   (MAFOR), Great Lakes Weather Broadcast (LAWEB) and unscheduled Notices to
   Mariners or Bulletins. F3C and J3C emissions are permitted. Coast stations
   on the Great Lakes must cease weather broadcasts which cause interference to
   stations  operating  on  156.800 MHz until the interference problem is
   resolved.

   with an agreed program, for the broadcast of information to ship stations
   concerning the environmental conditions in which vessels operate, i.e. ,
   weather; sea conditions; time signals; notices to mariners; and hazards to
   navigation.

   ^14Available only in the Puget Sound and the Strait of Juan de Fuca.

   ^15The frequency 156.525 MHz is to be used exclusively for distress, safety
