scope:
This draft European Telecommunication Standard (ETS) states the minimum requirements for radio transmitters and receivers, for use on ships, operating in either the Medium Frequency (MF) only or in the Medium and High Frequency (MF/HF) bands allocated in the International Telecommunications Union (ITU) Radio Regulations [1], to the Maritime Mobile Service (MMS).
This ETS refers to equipment for one or more of the following:
- Single SideBand (SSB) modulation for telephony transmission and reception;
- Frequency Shift Keying (FSK) or SSB modulation of a keyed sub-carrier to transmit and receive Digital Selective Calling (DSC) signals in accordance with CCIR Recommendation 493 [5].
This ETS also refers to radio equipment, which is not integrated with the DSC encoder or decoder, but defines the interfaces with such equipment.
NOTE: The requirements for integrated equipment may be found in other relevant ETSs.
The tests in this ETS are applicable to one or more of the following types of receiver:
- receivers for operating on all frequencies in the bands 1 605 kHz to 4 000 kHz or 1 605 kHz to 27,5 MHz as allocated in the Radio Regulations [1], to the MMS.
- receivers for DSC distress watchkeeping only purposes for MF DSC on 2 187,5 kHz;
- receivers for DSC distress watchkeeping purposes including scanning receivers for MF/HF DSC only on 2 187,5 kHz, 4 207,5 kHz, 6 312 kHz, 8 414 kHz, 12 577 kHz and 16 806,5 kHz.
Other spot frequency receivers, including scanning receivers, should meet all the requirements of this ETS and other relevant standards as applicable for the frequencies and modes provided.
This ETS includes the International Maritime Organisation (IMO) and ITU requirements included in the relevant provisions of the Radio Regulations [1], the International Convention on Safety Of Life At Sea (SOLAS) [3], and the IMO Resolutions A.421(XI), A.610(15), A.613(15), and A.694(17) [4].
If the equipment, or parts of it, are designed in such a manner that they can be used for other categories of maritime radiocommunication (e.g. Morse telegraphy or NBDP), those parts of the equipment should fulfil the relevant requirements of the appropriate standards for the service(s) in question.
