(Main)Electromagnetic compatibility and Radio spectrum Matters (ERM) - Technical characteristics and methods of measurement for shipborne watchkeeping receivers for reception of Digital Selective Calling (DSC) in the maritime MF, MF/HF and VHF bands
- Abstract
The present document states the minimum operational and performance requirements for shipborne receivers intended to be connected to an external installation, including a decoder for DSC, and used as receivers for watchkeeping DSC on board ships operating in the mobile MF, MF/HF and VHF band allocated in the ITU Radio Regulations [1] to the maritime mobile service, both in connection with distress and safety communication and in connection with general communication. These requirements include the relevant provisions of the ITU Radio Regulations [1], ITU-R Recommendations M.493-12 [3], M.541-9 [10], M.489-2 [9] and the IMO Resolutions A.803(19), A.804(19), A.806(19) and A.694(17). The present document specifies also technical characteristics, methods of testing and required test results for dedicated watchkeeping receivers for use with radio installations in the GMDSS as required by chapter IV of the SOLAS. It covers both receivers with analogue output or with digital DSC signal output interfaces or with both. DSC watchkeeping receivers may be a separate equipment or be integrated with a DSC or radiotelephone equipment. For integrated equipment the present document specifies the requirements and methods of testing of the DSC watchkeeping receivers only. DSC watchkeeping receivers can be either fixed-frequency receivers or, in MF/HF bands, scanning receivers. Requirements for the DSC equipment or radiotelephone equipment are given in EN 300 338-2 [12], EN 301 925 [11] and EN 300 373-1 [13] respectively.

SIST EN 301 033 V1.3.1:2010 is the SIST adoption of the ETSI standard for shipborne watchkeeping receivers used for Digital Selective Calling (DSC) in the maritime MF, MF/HF and VHF bands. It specifies minimum operational and performance requirements, technical characteristics, test methods and required test results for receivers used on ships for distress, safety and general communication, including use in the Global Maritime Distress and Safety System (GMDSS).
What does SIST EN 301 033 V1.3.1:2010 specify?
SIST EN 301 033 V1.3.1:2010 specifies the requirements for shipborne DSC watchkeeping receivers that connect to an external installation and include a DSC decoder. The document covers separate receivers and the receiver part of integrated DSC or radiotelephone equipment.
The standard is organized into clauses on scope, references, definitions and abbreviations, general and operational requirements, technical requirements, test conditions, environmental tests, MF/HF performance, VHF performance, and radiated measurement arrangements.
| Annex | What it covers |
|---|---|
| Annex A | Normative radiated measurements, including outdoor and indoor test sites, antennas, substitution methods and anechoic chamber arrangements |
| Annex B | Informative bibliography |
What are the key requirements of SIST EN 301 033 V1.3.1:2010?
General design and operation
Clause 4 requires the equipment to maintain continuous watch on the relevant DSC channels and to be suitable for shipboard use and continuous operation. In practice, this means the receiver has to be ready for alarm and calling duties without frequent intervention.
Clause 4 also requires accessible construction, replaceable main modules, protection against static voltage at the antenna input, and software protection. The software and memory rules matter because distress calling information must remain available and operator-programmed memory needs protection against power interruption.
Clause 4.6 defines the interfaces for analogue and digital DSC outputs, and for scanning control and frequency read-out where provided. This is important for integration with external DSC decoder equipment and with ship systems using IEC 61162-1 or ITU-T V.11.
Bands, channels and reception modes
Clause 5 defines the operating bands and call channels. MF covers 1 606,5 kHz to 4 000 kHz, HF covers 4 MHz to 27,5 MHz, and VHF covers 156 MHz to 174 MHz.
For distress, urgency and safety calling, the standard fixes specific watch channels, including 2 187,5 kHz in MF and channel 70 at 156,525 MHz in VHF. MF/HF scanning receivers may scan up to 6 frequencies, and the document sets rules for which distress frequencies must be included when the operator can customize the scan list.
Clause 5 also fixes the reception classes: F1B or J2B for MF/HF DSC and G2B for VHF DSC. For a buyer or test lab, this tells you what demodulation mode the equipment must support.
Test conditions and performance
Clause 6 sets normal and extreme test conditions, signal connections, test frequencies, standard test signals and measurement uncertainty. It also requires bit error ratio measurements for digital outputs and for analogue outputs via a linear FSK discriminator.
Clauses 7 to 9 then apply environmental and RF performance checks. These include vibration, dry heat, damp heat, low temperature and corrosion, followed by calling sensitivity, adjacent channel selectivity, co-channel rejection, intermodulation, spurious response, dynamic range, spurious emissions, antenna input protection and scanning efficiency.
What terms does SIST EN 301 033 V1.3.1:2010 define?
- assigned frequency - the centre of the frequency band assigned to a station.
- continuous watch - a watch that is not interrupted except for brief breaks caused by the ship’s own communications or maintenance/checks.
- performance check - the receiver check of calling sensitivity described in clause 7.2.
- DSC (Digital Selective Calling) - the calling system used for maritime mobile service distress, safety and general calls.
- GMDSS (Global Maritime Distress and Safety System) - the ship radio framework that uses these receivers for distress and safety communications.
- MF/HF - Medium Frequency and High Frequency, the bands used for maritime DSC watchkeeping in this standard.
- VHF - Very High Frequency, used here for DSC watchkeeping on channel 70.
Who uses SIST EN 301 033 V1.3.1:2010?
The standard is used by manufacturers of shipborne DSC watchkeeping receivers, designers of integrated DSC and radiotelephone equipment, and test laboratories that verify conformance. It is also relevant to ship equipment integrators, marine radio installers, and quality or procurement teams that need to confirm the receiver supports the required maritime channels, interfaces and environmental performance.
Which standards are used with SIST EN 301 033 V1.3.1:2010?
- ITU Radio Regulations - define the maritime mobile service bands and channel framework used by the receiver.
- ITU-R Recommendation M.493-12 - defines the maritime DSC system the receiver must demodulate.
- ITU-R Recommendation M.541-9 - gives operational procedures for DSC use.
- ITU-R Recommendation M.489-2 - provides technical characteristics for VHF radiotelephone channels.
- ITU-T Recommendation E.161 - guides keypad digit arrangement.
- ITU-T Recommendation V.11 - defines compatible digital interface levels and stop/start control signals.
- IEC 61162-1 - provides the digital maritime interface used for frequency control and read-out.
- IEC 60417 - supplies graphical symbols for equipment markings.
- ETSI EN 300 338-2 - covers DSC equipment; this standard points to it for the DSC generator/decoder functions.
- ETSI EN 301 925 - covers VHF radiotelephone transmitters and receivers used with related equipment.
- ETSI EN 300 373-1 - covers maritime MF and HF transmitters and receivers.
What does the SIST EN 301 033 V1.3.1:2010 document contain?
The document contains detailed test methods for the receiver’s calling sensitivity, selectivity, rejection, dynamic range, emissions and protection against strong signals. It also defines environmental test procedures for vibration, temperature cycling and corrosion so the receiver can be assessed for shipboard service conditions.
Annex A gives the radiated measurement arrangements used for spurious emissions and receiver sensitivity measurements, including outdoor site geometry, antenna positioning and optional indoor anechoic chamber setups. Clause 6.9 also gives measurement uncertainty limits and how to interpret test results in a conformance report.

1 Scope
The present document states the minimum operational and performance requirements for shipborne receivers intended
to be connected to an external installation, including a decoder for DSC, and used as receivers for watchkeeping DSC
on board ships operating in the mobile MF, MF/HF and VHF band allocated in the ITU Radio Regulations [1] to the
maritime mobile service, both in connection with distress and safety communication and in connection with general
communication.
These requirements include the relevant provisions of the ITU Radio Regulations [1], ITU-R Recommendations
M.493-12 [3], M.541-9 [10], M.489-2 [9] and the IMO Resolutions A.803(19), A.804(19), A.806(19) and A.694(17).
The present document specifies also technical characteristics, methods of testing and required test results for dedicated
watchkeeping receivers for use with radio installations in the GMDSS as required by chapter IV of the SOLAS.
It covers both receivers with analogue output or with digital DSC signal output interfaces or with both.
DSC watchkeeping receivers may be a separate equipment or be integrated with a DSC or radiotelephone equipment.
For integrated equipment the present document specifies the requirements and methods of testing of the DSC
watchkeeping receivers only.
DSC watchkeeping receivers can be either fixed-frequency receivers or, in MF/HF bands, scanning receivers.
Requirements for the DSC equipment or radiotelephone equipment are given in EN 300 338-2 [12], EN 301 925 [11]
and EN 300 373-1 [13] respectively.

1 Scope
The present document states the minimum operational and performance requirements for shipborne receivers intended
to be connected to an external installation, including a decoder for DSC, and used as receivers for watchkeeping DSC
on board ships operating in the mobile MF, MF/HF and VHF band allocated in the ITU Radio Regulations [1] to the
maritime mobile service, both in connection with distress and safety communication and in connection with general
communication.
These requirements include the relevant provisions of the ITU Radio Regulations [1], ITU-R Recommendations
M.493-12 [3], M.541-9 [10], M.489-2 [9] and the IMO Resolutions A.803(19), A.804(19), A.806(19) and A.694(17).
The present document specifies also technical characteristics, methods of testing and required test results for dedicated
watchkeeping receivers for use with radio installations in the GMDSS as required by chapter IV of the SOLAS.
It covers both receivers with analogue output or with digital DSC signal output interfaces or with both.
DSC watchkeeping receivers may be a separate equipment or be integrated with a DSC or radiotelephone equipment.
For integrated equipment the present document specifies the requirements and methods of testing of the DSC
watchkeeping receivers only.
DSC watchkeeping receivers can be either fixed-frequency receivers or, in MF/HF bands, scanning receivers.
Requirements for the DSC equipment or radiotelephone equipment are given in EN 300 338-2 [12], EN 301 925 [11]
and EN 300 373-1 [13] respectively.

ETSI ETSI EN 301 033 V1.3.1 (2010-09) 8 1 Scope The present document states the minimum operational and performance requirements for shipborne receivers intended to be connected to an external installation, including a decoder for DSC, and used as receivers for watchkeeping DSC on board ships operating in the mobile MF, MF/HF and VHF band allocated in the ITU Radio Regulations [1] to the maritime mobile service, both in connection with distress and safety communication and in connection with general communication. These requirements include the relevant provisions of the ITU Radio Regulations [1], ITU-R Recommendations M.493-12 [3], M.541-9 [10], M.489-2 [9] and the IMO Resolutions A.803(19), A.804(19), A.806(19) and A.694(17). The present document specifies also technical characteristics, methods of testing and required test results for dedicated watchkeeping receivers for use with radio installations in the GMDSS as required by chapter IV of the SOLAS. It covers both receivers with analogue output or with digital DSC signal output interfaces or with both. DSC watchkeeping receivers may be a separate equipment or be integrated with a DSC or radiotelephone equipment. For integrated equipment the present document specifies the requirements and methods of testing of the DSC watchkeeping receivers only. DSC watchkeeping receivers can be either fixed-frequency receivers or, in MF/HF bands, scanning receivers. Requirements for the DSC equipment or radiotelephone equipment are given in EN 300 338-2 [12], EN 301 925 [11] and EN 300 373-1 [13] respectively. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
