  § 80.357   Working frequencies for Morse code and data transmission.

   This section describes the working frequencies assignable to maritime
   stations for A1A, J2A, J2B (2000-27500 kHz band only), or J2D
   (2000-27500 kHz band only) 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.

                158

   (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.
      405-525 (kHz)
              ^1410
                425
                454

                480
              ^2512
              ^3518

   ^1The 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.

   ^2The 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.

   ^3The 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 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
   § 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 § 80.363(a)(2) of this chapter
   are also available for assignment to public coast stations for A1A,
   J2A, J2B, or J2D radiotelegraphy following coordination with government
   users.

   ^1All 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.

   (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
