  § 80.1091   Ship radio equipment—Sea areas A1, A2, and A3.

   This section contains the additional equipment requirements for ships
   that remain within sea areas A1, A2, or A3 at all times. Ships fitting
   in accordance with this section satisfy the requirements denoted in
   § 80.1087 or § 80.1089 for sea-areas A1 and A2. Ships fitting in
   accordance to this section have the option to comply with either the
   requirements of paragraph (a) or (b) of this section.

   (a) In addition to meeting the requirements of § 80.1085, ships subject
   to this section must be provided with:

   (1) An INMARSAT ship earth station capable of:

   (i) Transmitting and receiving distress and safety data communications;

   (ii) Initiating and receiving distress priority calls;

   (iii) Maintaining watch for shore-to-ship distress alert, including
   those directed to specifically defined geographical areas;

   (iv) Transmitting and receiving general radiocommunications, using
   either radiotelephony or direct-printing telegraphy; and

   (2) An MF radio installation capable of transmitting and receiving, for
   distress and safety purposes, on the frequencies:

   (i) 2187.5 kHz using DSC; and

   (ii) 2182 kHz using radiotelephony; and

   (3) A radio installation capable of maintaining a continuous DSC watch
   on the frequency 2187.5 kHz which may be separate from or combined with
   that required by paragraph (a)(2)(i) of this section; and

   (4) Means of initiating the transmission of ship-to-shore distress
   alerts by a radio service operating either:

   (i) Through the polar orbiting satellite service on 406.0-406.1 MHz
   (this requirement may be fulfilled by the EPIRB required by
   § 80.1085(a)(6), either by installing the EPIRB close to, or by allowing
   remote activation from, the position from which the ship is normally
   navigated); or

   (ii) On HF using DSC: or

   (iii) Through the INMARSAT geostationary satellite service, by an
   additional ship earth station.

   Note to paragraph (a)(4)(iii): For ships subject to this subpart,
   sailing only in domestic waters, alternative satellite system fitting
   may be considered. However, the satellite system fitted must comply
   with all features of the INMARSAT system for its intended function.
   These are shown in IMO Resolution A.801(19) and in IMO Resolution
   A.1001(25) (both incorporated by reference, see § 80.7). In any case,
   the alternative satellite system must provide continuous coverage for
   all sea areas in which the ship intends to sail.

   (b) In addition to meeting the requirements of § 80.1085, ships subject
   to this section must be provided with:

   (1) An MF/HF radio installation capable of transmitting and receiving
   on all distress and safety frequencies in the bands between 1605-27500
   kHz using DSC, radiotelephony, and narrow-band direct-printing
   telegraphy; and

   (2) Equipment capable of maintaining DSC watch on 2187.5 kHz, 8414.5
   kHz and on at least one of the distress and safety DSC frequencies
   4207.5 kHz, 6312 kHz, 12577 kHz, or 16804.5 kHz although it must be
   possible to select any of these DSC distress and safety frequencies at
   any time (this equipment may be separate from, or combined with, the
   equipment required by paragraph (b)(1) of this section); and

   (3) Means of initiating the transmission of ship-to-shore distress
   alerts by a radiocommunication service other than HF operating either:

   (i) Through the polar orbiting satellite service on 406.0-406.1 MHz
   (this requirement may be fulfilled by the 406.0-406.1 MHz EPIRB
   required by § 80.1085(a)(6), either by installing the 406.0-406.1 MHz
   EPIRB close to, or by allowing remote activation from, the position
   from which the ship is normally navigated); or

   (ii) Through the INMARSAT geostationary satellite service (this
   requirement may be fulfilled by an INMARSAT ship earth station).

   (4) In addition, ships must be capable of transmitting and receiving
   general radiocommunications using radiotelephony or direct-printing
   telegraphy by an MF/HF radio installation operating on working
   frequencies in the bands between 1605-4000 kHz and between 4000-27500
   kHz (this requirement may be fulfilled by the addition of this
   capability to the equipment required by paragraph (b)(1) of this
   section).

   (c) It must be possible to initiate transmission of distress alerts by
   the radio installations specified in paragraphs (a)(1), (a)(2), (a)(4),
   (b)(1), and (b)(3) of this section from the position from which the
   ship is normally navigated.
