   (a) The operational details of the stations transmitting maritime safety
   information in accordance with this section are indicated in the ITU List of
   Radiodetermination and Special Service Stations and the IMO Master Plan of
   Shore-Based Facilities.

   (b) The mode and format of the transmissions mentioned in this section is in
   accordance with the ITU-R Recommendation M.540 as specified in  Sec. 80.1101.

   (c) Maritime safety information is transmitted by means of narrow-band
   direct-printing telegraphy with forward error correction using the frequency
   518 kHz in accordance with the international NAVTEX system (see  Sec. 80.1077).

   (d) The frequency 490 kHz may be used, after full implementation of the
   GMDSS, for the transmission of maritime safety information by means of
   narrow-band direct-printing telegraphy with forward error correction (see
    Sec. 80.1077).

   (e) Internationally, the frequency 4209.5 kHz is used for NAVTEX-type
   transmissions by means of narrow-band direct-printing telegraphy with
   forward error correction (see  Sec. 80.1077).

   (f) Maritime safety information is transmitted by means of narrow-band
   direct-printing telegraphy with forward error correction using the
   frequencies 4210 kHz, 6314 kHz, 8416.5 kHz, 12579 kHz, 16806.5 kHz, 19680.5,
   22376 kHz, and 26100.5 kHz (see  Sec. 80.1077).

   (g) Maritime safety information is transmitted via satellite in the maritime
   mobile-satellite service using the band 1530–1545 MHz (see  Sec. 80.1077).
