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.

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.

broadcasts which cause interference to stations operating on 156.800
MHz until the interference problem is resolved.
\11\ The frequency 157.100 MHz is authorized for search and rescue
training exercises by state or local government in conjunction with
U.S. Coast Guard stations. Prior U.S. Coast Guard approval is
required. Use must cease immediately on U.S. Coast Guard request.

for ship to coast station communications.
\13\ Available for assignment to coast stations, the use of which is in
accord 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.
\14\ Available only in the Puget Sound and the Strait of Juan de Fuca.
