(Main)Maritime mobile transmitters and receivers for use in the MF and HF bands - Harmonised Standard covering the essential requirements of articles 3.2 and 3.3(g) of Directive 2014/53/EU
General Information
- Abstract
The present document specifies technical characteristics and methods of measurements for radio transmitters and
receivers, for use on vessels, 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 [i.9], to
the Maritime Mobile Service (MMS).
The present document refers to equipment for one or more of the following:
- Single SideBand (SSB) modulation for telephony transmission and reception (J3E);
- Frequency Shift Keying (FSK) or SSB modulation of a keyed sub-carrier to transmit and receive Digital
Selective Calling (DSC) signals.
The present document also refers to radio equipment with either an integrated or external DSC controller.
The requirements in the present document are applicable to receivers for operating on all frequencies in the bands
1 606,5 kHz to 4 000 kHz or 1 606,5 kHz to 27,5 MHz as allocated in the ITU Radio Regulations [i.9], to the MMS.
Other spot frequency receivers should meet all the requirements of the present document and other relevant standards as
applicable for the frequencies and modes provided.
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 - ETSI ETS 300 067 [i.4]), those parts of the equipment should
fulfil the relevant requirements of the appropriate standards for the service(s) in question e.g. ETSI ETS 300 067 [i.4].
The present document covers the essential requirements of article 3.2 and article 3.3(g) of Directive 2014/53/EU [i.1]
under the conditions identified in annex A.

ETSI EN 303 402 V2.1.1 (2017-05) - Maritime mobile transmitters and receivers for use in the MF and HF bands; Harmonised Standard covering the essential requirements of articles 3.2 and 3.3(g) of Directive 2014/53/EU
Overview
SIST EN 303 402 V2.1.1:2017 is a harmonised standard addressing the technical requirements for maritime mobile transmitters and receivers intended for use in the Medium Frequency (MF) and High Frequency (HF) bands. This Slovenian standard, which aligns with ETSI EN 303 402 V2.1.1, ensures compliance with articles 3.2 and 3.3(g) of the Radio Equipment Directive 2014/53/EU. The standard applies to shipborne radio equipment using frequencies allocated to the Maritime Mobile Service (MMS) as specified by the International Telecommunication Union (ITU) Radio Regulations.
Equipment covered by this standard supports:
- Single SideBand (SSB) modulation for voice transmissions (telephony)
- Digital Selective Calling (DSC) using Frequency Shift Keying (FSK) or SSB modulation of a sub-carrier
- Integration with internal or external DSC controllers
The document defines technical characteristics, measurement methods, and essential requirements that contribute to interoperability, safety, and legal compliance in maritime radio communications.
Key Topics
- Frequency Bands: Focuses on MF (1 606.5 kHz to 4 000 kHz) and HF (1 606.5 kHz to 27.5 MHz) bands assigned to maritime use.
- Distress and Safety Functions: Ensures the reliability of distress frequencies and functions in emergencies, including operational readiness and controls for distress signals.
- Emission Classes: Covers J3E (SSB telephony) and F1B (DSC) emission types, supporting both analogue and digital communication.
- Labelling and Controls: Specifies requirements for equipment labels, user controls, indicators, and protection against misuse or mishandling.
- Environmental and Electrical Testing: Includes requirements for performance under various environmental conditions such as temperature extremes, vibration, damp, corrosion, and power source variations.
- Receiver and Transmitter Performance: Outlines limits for spurious emissions, frequency accuracy, sensitivity, selectivity, intermodulation, and audio characteristics.
- Interoperability: Mandates compatibility with other maritime radiocommunication services where equipment is designed for multi-service use.
Applications
The standard is crucial for:
- Vessel Operators and Shipowners: Ensures onboard communications are safe, effective, and compliant with EU regulations, supporting emergency communications and operational radio traffic.
- Radio Equipment Manufacturers: Provides a framework for designing and testing shipborne MF/HF transmitters and receivers, ensuring products meet legal and safety requirements for CE marking in Europe.
- Maritime Safety Authorities: Assists in approving and inspecting radio installations on ships under national and international safety regulations.
- Integrators and Service Providers: Guides the integration of compliant MF/HF radio and DSC systems into broader ship navigation and control electronics (Navigacijska in krmilna oprema).
MF and HF radio equipment built to this standard supports long-range distress calling, routine communications, and integration with digital safety services both on coastal and ocean-going vessels.
Related Standards
To ensure comprehensive compliance and interoperability, consider the following related standards:
- ETSI EN 300 338 series - Standards for DSC on MF, HF, and VHF bands
- ETSI ETS 300 067 - NBDP (narrow-band direct-printing telegraphy) for maritime use
- IEC 60945 - General requirements for marine navigation and radiocommunication equipment (environmental conditions)
- ITU Radio Regulations - Frequency allocations and operational practices for the Maritime Mobile Service
- Directive 2014/53/EU (RED) - Radio Equipment Directive guiding essential requirements for all radio equipment within the EU
SIST EN 303 402 V2.1.1:2017 is essential for anyone involved in maritime mobile radio, offering a clear baseline for regulatory compliance, safety, and technological reliability in MF/HF shipboard communications.
