Sec.  80.1089   Ship radio equipment—Sea areas A1 and A2.

   This section contains the additional equipment requirements for ships that
   remain within sea areas A1 or A2 at all times. Ships fitting in accordance
   with this section satisfy the sea area A1 requirements denoted in  Sec. 80.1087.

   (a) In addition to meeting the requirements of  Sec. 80.1085, ships engaged on
   voyages  beyond sea area A1, but remaining within sea area A2, must be
   provided with:

   (1) 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;

   (2) 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)(1)(i) of this section; and

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

   (i) Through the polar orbiting satellite service on 406.0–406.1 MHz or the
   INMARSAT–E service in the 1.6 GHz band (this requirement may be fulfilled by
   the EPIRB required by  Sec. 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 if within
   INMARSAT coverage; this requirement may be fulfilled by an INMARSAT ship
   earth station.

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

   (c)  Ships subject to this section must be capable of transmitting and
   receiving   general   radiocommunications   using   radiotelephony  or
   direct-printing telegraphy by either:

   (1) A radio installation operating on working frequencies in the bands
   between 1605–4000 kHz or between 4000–27500 kHz (this requirement may be
   fulfilled by the addition of this capability to the equipment required by
   paragraph (a)(1) of this section); or

   (2) An INMARSAT ship earth station.
