Sec. 80.357 Morse code working frequencies.
This section describes the working frequencies assignable to
maritime stations for A1A or J2A radiotelegraphy.
(a) Ship station frequencies--(1) Frequencies in the 100-160 kHz
band. The following table describes the working carrier frequencies in
the 100-160 kHz band which are assignable to ship stations. A ship
station may also transmit on a radiotelegraphy working channel of a
coast station within the 100-160 kHz band when directed to do so by the
coast station provided interference is not caused to any land, fixed,
broadcast, or radiolocation station.

(2) Frequencies in the 405-525 kHz band. The following table
describes the working carrier frequencies in the 405-525 kHz band which
are assignable to ship stations. A ship station may transmit on a
radiotelegraphy working channel of a coast station in the 415-490 kHz
band when directed to do so by the coast station.

\1\ The frequency 410 kHz may be used on a secondary basis for the
transmission of radiodetermination information and for transmitting by
radiotelegraph radiodetermination related messages to direction-
finding stations.
\2\ The frequency 512 kHz may be used as a supplementary calling
frequency when 500 kHz is used for distress, safety and urgency
communications. The use of the 512 kHz as a working frequency is
prohibited in areas where it is used as a supplementary calling
frequency when 500 kHz is used for distress, safety, and urgency
communications.
\3\ The frequency 518 kHz is a receive only frequency by ship stations.
It is used by U.S. Coast Guard coast stations for NB-DP transmissions
of meteorological and navigational warnings to ships.
(3) Frequencies in the 2000-27500 kHz band. This paragraph describes
the
[[Page 80]]
working frequencies and Channel Series in the 2000-27500 kHz band which
are assignable to ship stations.
(i) Two Channel Series will be assigned for routine use to each ship
station. Frequencies from any other Channel Series may be used if the
frequencies in the assigned Channel Series are not adequate for
communications.

(ii) If the frequencies listed in paragraph (3)(i) of this section
are not adequate for communications, ship stations may use any of the
non-paired narrow-band direct-printing frequencies listed in
Sec. 80.361(b) of this part for A1A or J2A radiotelegraphy.
(b) Coast station frequencies--(1) Frequencies in the 100-27500 kHz
band. The following table describes the working carrier frequencies in
the 100-27500 kHz band which are assignable to coast stations located in
the designated geographical areas. The exclusive maritime mobile HF
bands listed in the table contained in Sec. 80.363(b) of this part are
also available for assignment to public coast stations for A1A or J2A
radiotelegraphy following coordination with government users.

\1\ All frequencies in this table are shown in kilohertz.
(2) Conditions of use. The following conditions are applicable to
these frequencies:
(i) Frequencies in the 100-160 kHz band are assignable to coast
stations for high seas communications only;
(ii) Frequencies above 5 MHz may be assigned primarily to stations
serving the high seas and secondarily to stations serving inland waters
of the United States, including the Great Lakes, under the condition
that interference will not be caused to any coast station serving the
high seas. Applicants for these frequencies must submit a substantial
showing of need based on the following factors:
(A) A schedule of each currently licensed Morse working frequency
and the expected use of the proposed frequencies;
(B) For additional frequencies within the same MHz band, a factual
showing of the 3 busiest hours of any 4 days within a consecutive 10 day
period for each of the 2 months immediately preceding the filing of the
application indicating that the applicant has used its currently
assigned frequencies within the same MHz band an aggregate average of at
least 40% of the 3 busiest hours of each day for exchanging
communications; and
(C) Any other facts that support the need for the proposed
assignment, e.g., evidence of radio interference by another station
located near enough to render a currently licensed frequency
substantially unusable.
(iii) The frequency 410 kHz may be used on a secondary basis for the
transmission of radiodetermination information and for transmitting by
radiotelegraph radiodetermination messages to direction-finding
stations; and
(iv) The frequency 512 kHz may be used as a supplementary calling
frequency when 500 kHz is used for distress, urgency and safety
communications. The use of the 512 kHz as a working frequency is
prohibited in areas where 500 kHz is used for distress, urgency and
safety communications.
