Sec.  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.

   (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)

                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  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(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.
