SIST EN 300 065-1 V1.1.3:2003 is the Slovenian standard adopting ETSI EN 300 065-1 V1.1.3 for narrow-band direct-printing telegraph equipment used in the NAVTEX system. It specifies the minimum technical characteristics and measurement methods for maritime receivers that automatically receive and print meteorological, navigational, and Search And Rescue (SAR) messages from NAVTEX coast stations.

What does SIST EN 300 065-1 V1.1.3:2003 specify?

SIST EN 300 065-1 V1.1.3:2003 specifies the minimum requirements for a Narrow-Band Direct-Printing (NBDP) maritime receiver operating in NAVTEX. The equipment is defined as a radio-frequency receiver with a signal processor and a printing device, and the standard ties its message format and system operation to ITU-R Recommendations M.625-3 and M.540-2.

The document is organized into:

• Scope and references
• General requirements
• Test conditions, power supply, and ambient temperatures
• Receiver and signal processor requirements
• Printing device requirements
• Interference considerations

In practice, this means the standard is focused on how the receiver should behave, how to measure its performance, and how to check that it still works under normal and extreme conditions.

What are the key requirements of SIST EN 300 065-1 V1.1.3:2003?

Receiver functions and message handling

SIST EN 300 065-1 V1.1.3:2003 requires the receiver to operate on 518 kHz, with any second or third maritime safety frequency selected manually. It also requires built-in test facilities to check the receiver, signal processor, and printing device, including the signal path from the antenna to an audio output.

The receiver must let the user select which coast stations are printed by detecting the B1 characters, and it must allow at least four message categories identified by B2 characters to be excluded, except for navigational warnings, gale warnings, and SAR messages. This matters because the equipment has to limit unwanted printout while still preserving the messages that are safety-critical.

Message storage, alarms, and print control

SIST EN 300 065-1 V1.1.3:2003 requires the equipment to avoid printing messages that were not correctly received or that have already been stored as correctly received, unless B3B4 = 00. It must store at least 100 message identifications, erase the oldest when memory is full, and remove a stored identification automatically after 60 to 72 hours.

The standard also requires an alarm for SAR messages, a paper-low or paper-out alarm, and asterisk marking for each invalid character. If paper runs out during printing, the identification of the incomplete message must not be stored, and no new identifications may be stored until paper is available again. In practice, this is about preserving message integrity and making sure the operator knows when printout or memory management affects reception.

Electrical safety and retention of settings

SIST EN 300 065-1 V1.1.3:2003 requires protection against excessive current, voltage, overheating, voltage transients, and accidental polarity reversal. Accessible metal parts must be capable of earthing, and live parts above 50 volts peak must be guarded or isolated.

The user-programmed memory related to station selection and message-category exclusion must survive power interruptions shorter than 6 hours. For users, this means receiver settings should not be lost during short outages.

Performance under test conditions

SIST EN 300 065-1 V1.1.3:2003 defines normal and extreme test conditions for temperature, humidity, and power supply. It sets the normal test signal, the artificial antenna arrangements, and the procedures for tests at 0 °C and 40 °C.

The receiver and signal processor are tested for call sensitivity, interference rejection and blocking, co-channel rejection, intermodulation, spurious emissions, and input-circuit protection. The character error ratio used in several limits is less than 4 x 10-2, and spurious emissions are limited to 1 nW for any discrete component. In practice, these tests show whether the receiver can still decode NAVTEX messages in the presence of noise, strong signals, and environmental stress.

Printing device requirements

SIST EN 300 065-1 V1.1.3:2003 requires the printing device to print received messages on paper, allow simple paper replacement, and hold enough paper for at least 200000 characters. It also requires legible print, low noise, and at least 32 characters per line.

For buyers and testers, this section matters because it links message reception to an output device that can be used reliably on board ship.

What terms does SIST EN 300 065-1 V1.1.3:2003 define?

• Narrow-Band Direct-Printing (NBDP) - A maritime direct-printing telegraph arrangement in which messages are received and printed automatically.
• NAVTEX - The maritime system covered by the standard for transmitting meteorological, navigational, and SAR information to ships.
• Search And Rescue (SAR) - The message type for rescue-related information that the receiver must treat as priority traffic.
• B1 characters - The characters used to identify coast stations for selective printing.
• B2 characters - The characters used to identify message categories that can be excluded.
• B3B4 - The message identity used in the standard’s rules for always-print messages.
• Character error ratio - The receiver performance measure used to judge whether a message is correctly received.

Who uses SIST EN 300 065-1 V1.1.3:2003?

SIST EN 300 065-1 V1.1.3:2003 is used by manufacturers of NAVTEX receivers, maritime equipment designers, test laboratories, and type-approval authorities. It is also relevant to shipowners, buyers, and quality managers who need to check that a receiver meets the expected NAVTEX performance and safety behaviour. The foreword also places it in the context of ETSI type-approval guidance for equipment used aboard ships.

What changed in SIST EN 300 065-1 V1.1.3:2003 from the previous edition?

SIST EN 300 065-1 V1.1.3:2003 is described as an editorial revision of ETS 300 065 made after the publication of Part 2. The history also records the earlier ETS 300 065 publication and Amendment 1 to the first edition.

Which standards are used with SIST EN 300 065-1 V1.1.3:2003?

• ITU-R Recommendation M.625-3 - Provides the direct-printing telegraph equipment message format used by the standard.
• ITU-R Recommendation M.540-2 - Gives the operational and technical characteristics for the NAVTEX system.
• CEPT Recommendation T/R 34-01 - Supplies the maritime mobile radio equipment environmental test conditions referenced by the standard.
• CISPR 16 - Provides the measuring apparatus and methods used for conducted spurious emissions.
• Solas Convention - Sets the shipboard safety context for electromagnetic compatibility with other radio and navigation equipment.

What does the SIST EN 300 065-1 V1.1.3:2003 document contain?

The document contains measurement methods for receiver performance, including the artificial antenna arrangements and the normal test signal at 518 kHz. It sets out tests for sensitivity, blocking, co-channel rejection, intermodulation, spurious emissions, and protection of input circuits.

It also contains the general operating rules for selecting coast stations, excluding message categories, handling memory of received messages, and issuing alarms for SAR and paper status. The printing device section covers print quality, line length, paper handling, and capacity. The environmental testing section points to the vibration, dry-heat, damp-heat, and low-temperature procedures used for type approval.
