1.3 Voice Radiocommunications
1.3.1 General
Superfluous Communications and Interference
Unnecessary Transmissions
Communications should be restricted to those necessary for the safe and
expeditious movement of vessels. Unnecessary transmissions are not permitted.
Profane and obscene language is strictly prohibited.
False Distress Transmissions
False distress signals are strictly prohibited.
Penalty:
Any person who knowingly transmits or causes to be transmitted any false
or fraudulent distress signal, call or message is guilty of an offence and
is liable, on summary conviction, to a penalty or to imprisonment, or to both.
Interference
All radio stations shall be installed and operated so as not to interfere
with or interrupt the working of another radio station.
The only situation under which you may interrupt or interfere with the
normal working of another station is when you are required to transmit a
higher priority call or message (for example, distress, urgency or safety
calls or messages).
Secrecy of Communications
Radio operators and all persons who become acquainted with radiocommunications are bound to preserve the secrecy of correspondence.
The contents or even the existence of correspondence transmitted, received or intercepted by a radio station should not be divulged, except to the addressee of the message or his accredited agent, or the properly authorized officials of the Government of Croatia or a competent legal tribunal, or an operator of a telecommunications system as is necessary for the furtherance of delivery of the communications. The foregoing restrictions do not apply to a message of distress, urgency, safety or to messages addressed to ALL STATIONS, that is weather reports, storm warnings, etc.
1.3.2 Communications Priorities
The order of priority for radiocommunications:
1. distress communications,
2. urgency communications,
3. safety communications,
4. communications relative to direction-finding bearings,
communications relative to the navigation, movement and needs of aircraft
engaged in search and rescue operations,
messages containing exclusively meteorological (weather)observations
destined to an official meteorological office,
communications related to the application of the United Nations Charter,
service messages relative to the working of the radiocommunications service
or to messages that have been previously transmitted,
all other communications.
1.4 Operating Procedures – Using imo Standard Phrases (smcp 2001)
1.4.1 General
The present chapter deals with the application of IMO Standard Marine Communication Phrases (SMCP 2001) in operating procedures used in maritime communication.
Microphone Techniques
The efficient use of radiotelephone depends to a large extent on the operator's method of speaking. As the distinctive sounds of consonants are apt to become blurred in the transmission of speech, words of similar length containing the same vowel sounds may sound alike. Special care is necessary in their pronunciation. Special care is also required in handling the microphone. Do not hold the microphone too close to your mouth because
it may cause distortion or slurring of words and you may have to repeat your message to be understood. Speak all words plainly and end each word clearly in order to prevent the running together of consecutive words. The following points should be kept in mind when using a radiotelephone.
Speed and rhythm of speech
Keep the rate of speech constant, neither too fast nor too slow. Remember that the operator receiving your message may have to write it down.
Preserve the rhythm of ordinary conversation. Avoid the introduction of unnecessary sounds such as "ER and "um" between words.
If the communication link is unreliable, or the wording of the text complex or confusing, use the command WORDS TWICE or, upon request, repeat the message using the phonetic alphabet. This should ensure that the information within the text of the message is received correctly.
