§  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;
