Training Information (valid for TU5160)

The System 5000 MF/HF is designed for “occupational use only” and is also classified as such.

It must only be used in the course of employment by individuals aware of both the hazards as well as the way to minimize those hazards.

The radio is thus NOT intended for use in an uncontrolled environment by general public.

The System 5000 MF/HF has been tested and complies with the FCC RF exposure limits for

“Occupational Use Only”. The radio also complies with the following guidelines and standards regarding RF energy and electromagnetic energy levels including the recommended levels for human exposure:

• FCC OET Bulletin 65 Supplement C, evaluating compliance with FCC guidelines for human exposure to radio frequency electromagnetic fields

• American National Standards Institute (C95.1) IEEE standard for safety levels with respect to human exposure to radio frequency electromagnetic fields, 3 kHz to 300

GHz

• American National Standards Institute (C95.3) IEEE recommended practice for the measurement of potentially hazardous electromagnetic fields – RF and microwaves

Below the RF exposure hazards and instructions in safe operation of the radio within the

FCC RF exposure limits established for it are described.

Warning:

Your radio set generates electromagnetic RF (radio frequency) energywhen it is transmitting.

To ensure that you and those around you are not exposed to excessive amounts of that energy (beyond FCC allowable limits for occupational use) and thus to avoid health hazards from excessive exposure to RF energy, FCC OET bulletin 65 establishes an Maximum

Permissible Exposure (MPE) radius of 6″ (1.8m) for the maximum power of your radio (150W selected) with a whip antenna having a maximum gain of 3.0dBi.

This means all persons must be at least 6″ (1.8m) away from the antenna when the radio is transmitting.

Installation:

1.

A whip antenna with a maximum power gain of 3 dBi must be mounted at least 12.6″

(3.9m) above the highest deck where people may be staying during radio transmissions.

The distance is to be measured vertically from the lowest point of the antenna. This provides the minimum separation distance which is in compliance with RF exposure requirements and is based on the MPE radius of 6″ (1.8m) plus the 6.6″ (2.0m) height of an adult.

2 On vessels that cannot fulfil requirements in item 1, the antenna must be mounted so that its lowest point is at least 6″ (1.8m) vertically above the heads of people on deck and all persons must be outside the 6″ (1.8m) MPE radius during radio transmission.

• Always mount the antenna at least 6″ (1.8m) from possible human access

• Never touch the antenna when transmitting

• Use only authorized T&T accessories

3.

If antenna has to be placed in public areas or near people with no awareness of the radio transmission, the antenna must be placed at a distance not less than 12″ (3.6m) from possible human access.

Failure to observe any of these warnings may cause you or other people to exceed FCC RF exposure limits or create other dangerous conditions.

1 MF/HF Fundamental info

Propagation of MF and HF Radio Waves.

MF/HF radiocommunications provide a medium and long range service. The 1.6-4 MHz marine band is intended primarily for coastal operation beyond normal VHF communication range. A reliable range of more than 150 nautical miles can be expected in most areas in the daytime, more in the nighttime. Propagation of the radio waves in this band is mainly by ground waves i.e. the waves from the transmitter aerial follow the earth’s curvature to the receiver aerial. The high frequency range 4 — 30 MHz can provide communication for hundreds or even thousands of nautical miles. The long range is achieved by sky waves reflected from the ionosphere. Propagation of the radio waves depends on a number of factors such as frequency, time of day, time of year, and solar activity. The channels allocated to the maritime mobile service in the HF range are divided into a number of bands:

4, 6, 8, 12, 16, 18, 22, 25 MHz to allow a suitable frequency band to be selected for communication dependent on distance and time of day.

Radiotelephony

The mode of emission used for telephony transmissions in the marine bands is SSB (singlesideband, J3E). On the international distress frequency 2182 kHz compatible AM (amplitude modulation, H3E) may be used in addition for communication with non-GMDSS ships. AM mode is used also when receiving broadcasting. The frequencies for radiotelephone distress and safety traffic in the HF bands are 4125 kHz, 6215 kHz, 8291 kHz, 12290 kHz, and 16420 kHz. Working frequencies for public correspondence with coast stations are arranged in pairs for duplex/semi-duplex operation. For the HF bands these channels are allocated numbers by ITU on an international basis. In addition a number of simplex frequencies are available in each band for ship-to-ship communication.

Radiotelex

Marine telex is also referred to as (NBDP) ‘Narrow Band Direct Printing’. Due to the narrow bandwidth of the transmissions, a longer range may be expected compared to radiotelephony. The frequencies for radiotelex distress and safety traffic are 2174.5 kHz, 4177.5

kHz, 6268 kHz, 8376.5 kHz, 12520 kHz, and 16695 kHz. Working frequencies for public correspondence with coast stations are arranged in pairs. For the HF bands these channels are allocated numbers by ITU on an international basis. In addition a number of simplex frequencies are available in each band for ship-to-ship communication.

DSC

DSC (Digital Selective Calling) is an automatic calling system which allows a specific station to be contacted and made aware that a station wishes to communicate with it. In addition to calls to specific stations the system can also be used to call groups of ships and this is of significance for its use for DSC distress alerting. DSC is an alerting signal only and the communication which follows the call is made on an appropriate frequency band using radiotelephony or radiotelex. The frequencies for DSC distress and safety calling are 2187.5

kHz, 4207.5 kHz, 6312 kHz, 8414.5 kHz, 12577 kHz, and 16804.5 kHz. Calling frequencies for public correspondence with coast stations are arranged in pairs, both international and national frequencies are assigned. In addition the frequency 2177 kHz may be used for shipto-ship calling.

Wait until transmission of the traffic list has finished and the channel is free. Call the coast station on the working frequency on which the traffic list was received or as instructed by the coast station.

• Hook off the handset.

• Press the PTT key on the handset when speaking.

Say:

• <Called station’s name (3 times)>

• ‘This is’ <Your ship’s name (3 times)>

• ‘Over’

• Release the PTT key to listen.

• When answered:

Follow the instructions from the coast station. The coast station may ask for further identification, information on position and next port of call, and may suggest another working channel for the traffic to follow. If the coast station is not ready to receive traffic immediately it may ask you to wait for a specific number of minutes.

PTT only when you are talking. If on a simplex channel (in other words, a channel that can carry only one transmission at a time), always say “Over” just before releasing.

Direct Dial Calls:

If a phone number was included in the call then immediately after reception of the acknowledgement the DSC call is repeated on the working frequency. This call may be used by the coast station for channel quality evaluation. If the channel quality evaluation indicates that communication will be satisfactory, the coast station sends a DSC acknowledgement and starts dialing the subscriber number. Dialing tones may be heard in the speaker or handset.

When the handset is placed on hook after a Direct Dial call a DSC call indicating ‘End of call’ is send to terminate the connection. The coast station may respond with a DSC call indicating the chargeable duration of the connection.

Geographic Area Computation

When transmitting a geographical area call, the user is requested to enter the position of the ship (x,y) and the radius of interest r. This information is transformed to a square with a corner point and the length of its sides and . Finally the DSC message is transmitted over the air. See the figure below for an illustration of the relation between the user input (the white circle) and the information transmitted over the air (the grey square).

The center point is the position of the ship measured in degrees and minutes, whereas the radius of interest is given in nautical miles.

The corner point of the square and the length of its sides is given in degrees. Note that these values are rounded to degrees, and due to the requirement that the square shall include the entire circle; this will result in a slightly larger area than defined by the user input.

Also note that special handling is required when close to the poles. If the latitude of the corner point is transformed to a value greater that 90° then is set to 90° and the length of the square is reduced correspondingly. If the length of the square is greater than 90° then is set to 90°.

9 1 MF/HF Fundamental info Propagation of MF and HF Radio Waves. MF/HF radiocommunications provide a medium and long range service. The MHz marine band is intended primarily for coastal operation beyond normal VHF communication range. A reliable range of more than 150 nautical miles can be expected in most areas in the daytime, more in the nighttime. Propagation of the radio waves in this band is mainly by ground waves i.e. the waves from the transmitter aerial follow the earth s curvature to the receiver aerial. The high frequency range 4-30 MHz can provide communication for hundreds or even thousands of nautical miles. The long range is achieved by sky waves reflected from the ionosphere. Propagation of the radio waves depends on a number of factors such as frequency, time of day, time of year, and solar activity. The channels allocated to the maritime mobile service in the HF range are divided into a number of bands: 4, 6, 8, 12, 16, 18, 22, 25 MHz to allow a suitable frequency band to be selected for communication dependent on distance and time of day. Basic Radiotelephony The mode of emission used for telephony transmissions in the marine bands is SSB (singlesideband, J3E). On the international distress frequency 2182 khz compatible AM (amplitude modulation, H3E) may be used in addition for communication with non-gmdss ships. AM mode is used also when receiving broadcasting. The frequencies for radiotelephone distress and safety traffic in the HF bands are 4125 khz, 6215 khz, 8291 khz, khz, and khz. Working frequencies for public correspondence with coast stations are arranged in pairs for duplex/semi-duplex operation. For the HF bands these channels are allocated numbers by ITU on an international basis. In addition a number of simplex frequencies are available in each band for ship-to-ship communication. Radiotelex Marine telex is also referred to as (NBDP) Narrow Band Direct Printing. Due to the narrow bandwidth of the transmissions, a longer range may be expected compared to radiotelephony. The frequencies for radiotelex distress and safety traffic are khz, khz, 6268 khz, khz, khz, and khz. Working frequencies for public correspondence with coast stations are arranged in pairs. For the HF bands these channels are allocated numbers by ITU on an international basis. In addition a number of simplex frequencies are available in each band for ship-to-ship communication. DSC DSC (Digital Selective Calling) is an automatic calling system which allows a specific station to be contacted and made aware that a station wishes to communicate with it. In addition to calls to specific stations the system can also be used to call groups of ships and this is of significance for its use for DSC distress alerting. DSC is an alerting signal only and the communication which follows the call is made on an appropriate frequency band using radiotelephony or radiotelex. The frequencies for DSC distress and safety calling are khz, khz, 6312 khz, khz, khz, and khz. Calling frequencies for public correspondence with coast stations are arranged in pairs, both international and national frequencies are assigned. In addition the frequency 2177 khz may be used for shipto-ship calling. 3
