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 comm unication 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 (single-sideband, 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 ‘Narrow Band Direct Printing’
(NBDP). 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 ‘all ships’ and 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 ship-to-ship calling.

Two-tone Alarm Signal
To switch to the Two Tone Alarm Signal display: Press the Shift key
followed by the Alarm key.
Transmission of the two tone alarm signal will continue for 45
seconds, but may be stopped manually by pressing the STOP key in
the frequency display. When the alarm signal ceases press the
handset key and transmit your distress message by speaking into
the handset microphone with a clear and calm voice.
Two-tone Alarm Display Functions:
Listening for Calls
Coast stations transmit traffic lists consisting of call signs/names of
the ships for which they have traffic.
The traffic lists are sent at specified times and at intervals of typically
two hours. They are broadcasted on the normal working frequencies
on the coast station. Ships should, as far as possible, listen to the
traffic lists transmitted by relevant coast stations. On hearing their
call sign they should establish communication as soon as they can
do so.
1. Select the appropriate station.
2. Select the channel on which traffic lists are transmitted.
3. Switch loudspeaker on and adjust volume to an appropriate
level.
If on HF, traffic lists are transmitted in more frequency bands
simultaneously, search for the channel with the best propagation
conditions.
Making a Manual Call
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.
1. Hook off the handset.
2. Press the PTT key on the handset when speaking.
Say:
1. <Called station’s name (3 times)>
2. ‘This is’ <Your ship’s name (3 times)>
3. ‘Over’
3. Release the PTT key to listen.
4. 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.
Note: The two tone alarm signal generator is intended for alerting
ships not yet equipped with DSC equipment. It may be used only to
announce a distress message and primarily on the frequency 2182
kHz in AM telephony mode.
