SIST ETS 300 067:1999 is the Slovenian adoption of an ETSI European Telecommunications Standard for radiotelex equipment used in the maritime MF/HF service. It specifies minimum technical characteristics, operating features and methods of measurement for shipboard radiotelex equipment, including integrated equipment and combinations of a maritime transmitter/receiver with external NBDP equipment.

What does SIST ETS 300 067:1999 specify?

SIST ETS 300 067:1999 specifies minimum requirements for radiotelex equipment for use on board ships, together with the test conditions and measurement methods used to verify them. The document covers both integrated equipment and separate transmitter/receiver plus external NBDP arrangements, and it also expects relevant IMO performance standards and radio regulations to be met.

The document is organized into:

• Clause 1 - Scope
• Clause 2 - General requirements
• Clause 3 - Test conditions
• Clause 4 - Integrated equipment, transmitting part
• Clause 5 - Integrated equipment, receiving part
• Clause 6 - Radiotelex modems, modulating part
• Clause 7 - Radiotelex modems, demodulating part
• Clause 8 - RF transmitters used with radiotelex modems
• Clause 9 - RF receivers used with radiotelex modems
• Clause 10 - Station requirements
• Clause 11 - Interference
• Clause 12 - Operational procedures
• Annex A - Bibliography

What are the key requirements of SIST ETS 300 067:1999?

General and installation requirements

Clause 2 requires ship-suitable construction, clear labeling, and controls that are simple to use in practice. That matters because crew need to identify functions quickly, avoid accidental operation, and maintain the equipment at sea.

Clause 2.1 requires the equipment to carry visible type designation and permanent serial identification, and each unit must remain clearly identifiable. It also calls for accessible maintenance information and a comprehensive technical description for type testing.

Clause 2.1 and 2.7 also require practical operating features such as priority handling between multiple operating positions, incoming-call priority over local use, support for message composition and verification of at least 4000 characters, and a printing facility. In daily use, this means the equipment must support real shipboard traffic, not only bench testing.

Clause 2.2 requires indicators for supply voltage, standby, call detection, transmitter inhibit on continuous B or Y signalling, and RF output to the antenna. Clause 2.5 adds protection against excessive current, voltage transients, polarity reversal, and dangerous access to live parts.

Clause 2.6 sets a fast start-up expectation: the equipment should meet the specification within one minute of switch-on, or after a 30-minute warm-up for heated parts such as crystal ovens. Clause 2.3 also requires stored ship identity and process information to survive power interruptions.

Transmitter and receiver performance

Clauses 4, 5, 8 and 9 define the radio-frequency performance for both integrated equipment and separate transmitter and receiver units. The equipment must work on assigned radiotelex frequencies in the maritime mobile service, including the bands 415 kHz to 526.5 kHz, 1605 kHz to 4.0 MHz, and 1605 kHz to 28 MHz, with certain commonly used frequencies readily accessible where applicable.

The transmitter must use F1B or J2B emission, identify the assigned frequency clearly, and change frequency within 15 seconds, or 25 seconds for the 415 kHz to 526.5 kHz band. This matters because radiotelex operation depends on fast channel changes and correct frequency alignment.

Clause 4 also requires a 170 Hz frequency shift, automatic inhibition of transmission within one minute if a continuous B or Y signal is generated, and protection against damage if the antenna is short-circuited or open-circuited for at least five minutes at maximum power. The same family of checks appears again for stand-alone transmitters in clause 8.

The receiver must accept F1B and J2B signals, support direct operator access to selectable emission classes where more than one is available, and tune from any frequency to any other within 15 seconds. Clause 5 and clause 9 also cover calling sensitivity, adjacent channel selectivity, blocking, co-channel rejection, intermodulation, vibration effects, tuning error and spurious response rejection.

Clause 9.3 allows either continuous tuning or synthesized tuning in steps no greater than 100 Hz. Clause 9.4 requires frequency conversion to preserve MARK and SPACE polarity, and it allows an output frequency change to 1500 Hz to support existing NBDP equipment.

Clause 5.9 and 9.12 require protection of receiver input circuits against a 30 V r.m.s. unmodulated signal for 15 minutes and a direct current path from antenna terminal to chassis not exceeding 100 kΩ. In practice, that is a robustness check for installation faults and static voltages.

Modem and station behavior

Clause 6 sets the modulating part of radiotelex modems to 100 baud with a clock accuracy of 30 ppm or better. It requires at least one output type - binary digital or audio - and, for audio output, it specifies the 1615 Hz and 1785 Hz tone mapping used to represent Y and B.

Clause 7 sets the demodulating part to accept an audio input with a 170 Hz frequency shift and 1700 Hz center frequency. Clause 6.5 and 7.4 define timing for transmitter keying and receiver reactivation, including an adjustable transmit lead time from 0 ms up to at least 100 ms and receiver reactivation not exceeding 12 ms after the last bit.

Clause 10 covers station-level behaviour. The station must automatically activate the transmitter when a selective call matches the equipment identity, and in ARQ operation the master station must change to standby after 128 cycles if the circuit is not established. Scanning receivers, phasing maintenance, answer time and station delay time are also part of the station checks.

Clause 11 requires reasonable electromagnetic compatibility with other onboard radio and navigation equipment, and clause 12 checks that operating procedures conform to the relevant CCIR Recommendations. That makes the standard useful not only for equipment design, but also for proving that the shipboard operating sequence is correct.

What terms does SIST ETS 300 067:1999 define?

• Radiotelex equipment - Direct-printing telegraph equipment with automatic identification and error correction for the maritime mobile MF/HF radio service.
• Narrow Band Direct Printing (NBDP) - The direct-printing telegraph method used by this standard for maritime text transmission.
• Forward Error Correcting (FEC) - An operating mode in which the system sends information so that errors can be corrected without repeating the message in the same way as ARQ.
• Automatic Repetition reQuest (ARQ) - An operating mode in which the receiving side controls repetition to recover incorrect blocks.
• Automatic Gain Control (AGC) - A receiver control that adjusts gain so varying signal levels remain usable for decoding.
• F1B - The emission class used for radiotelex signaling with frequency-shifted digital information and no sub-carrier for automatic reception.
• J2B - The emission class that uses single sideband with a modulating sub-carrier and suppressed carrier for radiotelex operation.

Who uses SIST ETS 300 067:1999?

SIST ETS 300 067:1999 is used by manufacturers of shipborne MF/HF radiotelex equipment, test laboratories, approval bodies, shipyards, marine electronics installers, and maintenance teams. It is also relevant to procurement and quality managers who need to specify type-tested equipment for maritime mobile service use.

In practice, these users rely on the standard when designing equipment, checking interfaces, running type approval tests, verifying transmitter and receiver performance, and confirming that shipboard radiotelex installations behave correctly in FEC and ARQ operation.

Which standards are used with SIST ETS 300 067:1999?

The document names several companion standards and references that shape its technical framework:

• IMO Assembly Resolution A.569(14) - provides the general requirements for ship-borne radio equipment forming part of GMDSS.
• IMO Assembly Resolution A.613(15) - provides performance standards for ship-borne MF/HF radio installations capable of voice communication, NBDP and digital selective calling.
• CEPT Recommendation T/R 34-01 - supplies maritime mobile radio equipment specifications; Annex VI is treated as part of this standard, and later references point to Annex 1 and Annex 7 for related transmitter and receiver requirements.
• CCIR Recommendation 625 - provides the direct-printing telegraph system with automatic identification and error correction used by maritime radiotelex.
• CCIR Recommendation 490 - covers the introduction of direct printing telegraph equipment in the maritime mobile service.
• CCIR Recommendation 491-1 - covers translation between identity numbers and identities for direct printing telegraphy.
• CCITT Recommendation F.130 - covers maritime answer-back codes.
• CCITT Recommendations V.10, V.24 and V.28 - define electrical and interchange-circuit characteristics for binary interfaces.
• CCITT Recommendation E.161 and Q.11 - support keypad arrangement and numbering-plan conventions.
• CISPR Publication 16 - provides radio-interference measuring apparatus and measurement methods.
• Convention on the Safety of Life at Sea (SOLAS), as amended - provides the maritime safety context for compatibility and onboard installation expectations.

What does the SIST ETS 300 067:1999 document contain?

SIST ETS 300 067:1999 contains detailed test conditions, standard test signals, artificial antenna arrangements, and procedures for connecting test signals to NBDP encoders and decoders. It also contains requirement-and-test-method pairs for transmitter power, frequency accuracy, stability, unwanted emissions, receiver sensitivity, selectivity, blocking, vibration performance, and protection of input circuits.

The document includes the operational features needed for shipboard use, such as selective calling, message preparation, printing, frequency scanning, automatic transmitter activation, and ARQ operation. It also includes Figures 1 and 2, which show the limits for unwanted emissions and spurious signal components.

Foreword
This European Telecommunications Standard (ETS) has been produced by the Radio Equipment and
Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI) and
has undergone the ETSI standards approvals procedure.
The standard sets out the minimum requirements for the use of radiotelex equipment aboard ships,
operating in the maritime mobile MF/HF radio service. Equipment must be capable of transmitting on one or
more of the frequency bands assigned to the service (415 kHz to 526.5 kHz, 1605 kHz to 4.0 MHz, or 1605
kHz to 28MHz).
The standard incorporates the requirements of International Maritime Organisation (IMO) Assembly
Resolutions A 569(14) and A 613(15), CCIR Recommendations 490, 491-1 and 625 and CCITT
Recommendation F.130. It includes the performance standards for Narrow-Band Direct Printing (NBDP)
equipment operating in the Global Maritime Distress and Safety System (GMDSS). Where the equipment is
provided with a digital input panel, it must comply where practicable with CCITT Recommendation
E.161/Q.11.

1 Scope
1)
This standard states the minimum requirements for radiotelex equipment for use on board ships. These
requirements include the relevant provisions of the Radio Regulations and the performance standards for
shipborne MF/HF radio installations for Narrow Band Direct Printing (NBDP) equipment operating in the
Global Maritime Distress and Safety System (GMDSS), and of the performance standards Res. A 569(14)
and Res. A 613(15) as adopted by the International Maritime Organization (IMO).
Annex VI of CEPT Recommendation T/R 34-01, CCIR Recommendation 625, 490, 491-1 and CCITT
Recommendation F 130 are regarded as a constituent part of this standard.
Maritime radiotelex equipment shall use the error-detecting and correcting system used for direct-printing
telegraphy in the maritime mobile service as described in CCIR Recommendation 625.
The equipment shall be able to operate in the Forward Error Correcting (FEC) and Automatic Repetition
reQuest (ARQ) modes in accordance with CCIR Recommendation 625.
Maritime radiotelex equipment may consist of integrated equipment or of a combination of a maritime mobile
transmitter/receiver and external NBDP equipment. Where such a combination is used the requirements for

Foreword
This European Telecommunications Standard (ETS) has been produced by the Radio Equipment and
Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI) and
has undergone the ETSI standards approvals procedure.
The standard sets out the minimum requirements for the use of radiotelex equipment aboard ships,
operating in the maritime mobile MF/HF radio service. Equipment must be capable of transmitting on one or
more of the frequency bands assigned to the service (415 kHz to 526.5 kHz, 1605 kHz to 4.0 MHz, or 1605
kHz to 28MHz).
The standard incorporates the requirements of International Maritime Organisation (IMO) Assembly
Resolutions A 569(14) and A 613(15), CCIR Recommendations 490, 491-1 and 625 and CCITT
Recommendation F.130. It includes the performance standards for Narrow-Band Direct Printing (NBDP)
equipment operating in the Global Maritime Distress and Safety System (GMDSS). Where the equipment is
provided with a digital input panel, it must comply where practicable with CCITT Recommendation
E.161/Q.11.

1 Scope
1)
This standard states the minimum requirements for radiotelex equipment for use on board ships. These
requirements include the relevant provisions of the Radio Regulations and the performance standards for
shipborne MF/HF radio installations for Narrow Band Direct Printing (NBDP) equipment operating in the
Global Maritime Distress and Safety System (GMDSS), and of the performance standards Res. A 569(14)
and Res. A 613(15) as adopted by the International Maritime Organization (IMO).
Annex VI of CEPT Recommendation T/R 34-01, CCIR Recommendation 625, 490, 491-1 and CCITT
Recommendation F 130 are regarded as a constituent part of this standard.
Maritime radiotelex equipment shall use the error-detecting and correcting system used for direct-printing
telegraphy in the maritime mobile service as described in CCIR Recommendation 625.
The equipment shall be able to operate in the Forward Error Correcting (FEC) and Automatic Repetition
reQuest (ARQ) modes in accordance with CCIR Recommendation 625.
Maritime radiotelex equipment may consist of integrated equipment or of a combination of a maritime mobile
transmitter/receiver and external NBDP equipment. Where such a combination is used the requirements for
integrated equipment shall apply to that combination.
If the equipment, or parts of it, is designed in such a manner that it can also be used for other categories of
maritime radio communication (e.g. radiotelephony), the relevant parts of the equipment shall furthermore
fulfil the requirements of the relevant standards applicable for the service(s) in question.
