Additional radio equipment to be provided for area A2 vesselsU.K.
12.—(1) In addition to meeting the requirements of regulation 10, every area A2 vessel shall be provided with–
(a)an MF radio installation capable of transmitting and receiving, for distress and safety purposes, on the frequencies–
(i)2,187.5 kHz using DSC; and
(ii)2,182 kHz using radiotelephony;
(b)an MF radio installation capable of maintaining a continuous listening watch on the frequency 2,187.5 kHz using DSC; such installation may be separate from, or combined with, that required by sub-paragraph (a)(i); and
(c)means of initiating the transmission of ship-to-shore distress alerts by a radio installation, other than an MF radio installation, operating either–
(i)through the Cospas-Sarsat satellite service in the 406 MHz band; this requirement may be fulfilled by the satellite EPIRB required by regulation 10(f) if it is installed close to, or capable of remote activation from, the position from which the vessel is normally navigated;
(ii)on HF using DSC; or
(iii)through the INMARSAT geostationary satellite service; this requirement may be fulfilled by–
(a)the equipment specified in paragraph (3)(b), or
(b)the satellite EPIRB required by regulation 10(f) if it is installed close to, or capable of remote activation from, the position from which the vessel is normally navigated.
(2) Means shall be provided to initiate transmission of distress alerts by the radio installations specified in paragraph (1)(a) and (1)(c) from the position from which the vessel is normally navigated.
(3) The vessel shall, in addition, be capable of transmitting and receiving general radio communications using radiotelephony or direct-printing telegraphy by either–
(a)a radio installation operating on working frequencies in the bands between 1,605 kHz and 4,000 kHz or between 4,000 kHz and 27,500 kHz; this requirement may be fulfilled by the addition of this capability to the equipment required by paragraph (1)(a); or
(b)an INMARSAT ship earth station.
