§ 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 limitations 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 kHz,
   2738.0 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.
