§ 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.
^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 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.
