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 see 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.

[[Page 96]]

    (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.

\1\ Limited to a peak envelope power of 150 watts.                      
\2\ Available 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.

    (2) Ship stations may conduct radioprinter communications with 
private coast stations on frequencies within these bands which are 
assigned to their associated private coast stations;
    (3) Any alphanumeric code may be used; and
    (4) The bandwidth of radioprinter communications on frequencies 
within these bands must not exceed 300 Hz.
    (e) Frequencies in the 2000-27500 kHz band for medical advisory 
communications. (1) Private coast stations may be authorized to use any

Government and non-Government fixed or fixed and mobile radio services 
shown in the Commission's Table of Frequency Allocations contained in 
Sec. 2.106 of this chapter for communications with ship stations to 
provide medical treatment information or advice. Assignment of these 
frequencies is subject to the following limitations:
    (2) No protection is provided from harmful interference caused by 
foreign stations; and
    (3) A private coast station must cease operations on a frequency 
that causes harmful interference to a foreign station.
    (f) Frequencies in the 156-162 MHz band. The following tables 
describe the carrier frequencies available in the 156-162 MHz band for 
radiotelephone communications between ship and private coast stations. 
(Note: the letter ``A'' following the channel designator indicates 
simplex operation on a channel designated internationally as a duplex 
channel.)
