Installation
Mounting a fixed NGT station
A fixed NGT AR or SR station is most commonly mounted
using a desk console (Codan part number 15-10471). A fixed
NGT AR Voice or VR station may be mounted using a desk
console (Codan part number 15-00766). For general guidance
on suitable locations for equipment and installing the fixed
station see the reference material on the enclosed CD.
Desk console
The pre-assembled NGT Desk Console (Codan part number
15-10471, used with the NGT AR and SR Transceivers only)
combines a handset, a goose-neck microphone, a junction box,
an in-built speaker, and a headphone jack (see Figure 3 on
page 24). The Code 766 Desk Console (Codan part number
15-00766, used with the NGT AR Voice and VR Transceivers
only) does not have an internal junction box or attached
handset. The handset connects to the rear of the console. The
console cradles the handset.
RF unit and transceiver supply
The RF unit and the transceiver supply are self-contained and
are usually stacked loosely. If you want to mount the RF unit
and/or the transceiver supply, contact your Codan
representative to obtain a rack-mounting unit or the
appropriate mounting cradles.
WARNING
If you are mounting an RF unit in a cradle, do
not fit rubber feet to the bottom of the RF unit.
NOTE
If you are transferring a mobile station to a fixed
station, and you are not mounting the RF unit in
a cradle, rubber feet can be fitted to the bottom
of the RF unit. The rubber feet are available
from Codan (Codan part number
30-11208-000).

The HF band is the range of frequencies between 3 and
30 MHz. HF transceivers usually cover a frequency range of
1.6 to 30 MHz.
Codan HF transceivers transmit on single sidebands. This
reduces the power required to send HF signals and increases
the number of channels available within the HF spectrum.
HF transceivers are primarily used for long-range
communication where distances of 3000 km (1800 mi) and
more are possible. Obstructions such as buildings and
mountains have little effect on long-range communication. HF
radio can cover such large distances because of the way the
transmitted radio signal propagates.
HF radio waves propagate in three ways simultaneously:
•
ground wave
•
direct wave
•
sky wave
Ground wave
The ground wave travels near the ground for short distances,
typically up to 100 km (60 mi) over land and 300 km (190 mi)
over sea. The distance covered depends upon the operating
frequency, transmission power, and type of terrain.
Direct wave
The direct wave travels in a direct line-of-sight from the
transmitter to the receiver.

HF radio transmission
Sky wave
The sky wave is the most important form of HF propagation.
The radio wave is transmitted toward the sky and is reflected
by the ionosphere to a distant receiver on earth.
The reflective properties of the ionosphere change throughout
the day, from season to season, and yearly.

Frequency, distance and time of day
The extent to which a radio wave is reflected depends on the
frequency that is used. If the frequency is too low, the signal is
absorbed by the ionosphere. If the frequency is too high, the
signal passes straight through the ionosphere. Within the HF
band, low frequencies are generally considered to be in the
range of 2 to 10 MHz. High frequencies are above 10 MHz.
A frequency chosen for daytime transmission may not
necessarily be suitable for night-time use. During the day, the
layers of the ionosphere are thick. The layers absorb lower
frequencies and reflect higher frequencies. At night, the
ionosphere becomes very thin. The low frequencies that were
absorbed during the day are reflected, and the high frequencies
that were reflected during the day pass straight through.
Summer HF communications usually operate on higher
frequencies than those used in winter over the same distance.

HF radio transmission
Solar activity varies over an 11 year cycle. Higher frequencies
need to be used during periods of peak activity.
It is important to remember that you may need to change the
frequency you are using to achieve the best communication.
The general rules of thumb for HF communication are:
•
the higher the sun, the higher the frequency
•
the further the distance, the higher the frequency
Channels and modes
A channel is a name that is given to a frequency or a pair of
frequencies, e.g. ‘Channel 1’, ‘4500’ and ‘Headquarters’. The
frequencies may be any frequencies within the HF range.
Each channel has one or more modes associated with it. Each
mode indicates a sideband that can be used with the channel,
such as USB or LSB. When you make a call you need to
specify the channel and the mode you want to use.
Table 6 shows examples of channels and the information
associated with them.

Networks and scanning
A network is two or more stations that use the same
frequencies and call system to communicate. The frequencies
are allocated by a government authority and enable the
network to maintain HF communication throughout the day
and night.
The call system is the method the network uses to make and
receive calls. For example, in networks that use the Codan
Selcall or Open Selcall call system to make calls, the user
enters the address of the station they want to call, then selects
the channel/mode on which to make the call. In networks that
use the ALE/CALM call system, the transceiver selects the
best channel/mode for the call.
The transceiver can be set to scan the channel/modes used by
your network to detect incoming calls. It is recommended that
when you are not using the transceiver to communicate you
switch scanning on. This ensures that you can receive calls
from stations in your network.
Etiquette for the use of HF radio
There is a standard procedure for communicating over HF
radio. Before you begin transmitting, switch off scanning,
select a channel, then press PTT on the handset to initiate
tuning of the antenna. Listen to the channel that you are going
to use and ensure that there is no voice or data communication
taking place. You may need to wait until the channel is clear or
select another channel.
When you first establish communication with another station
it is customary to state their call sign and then your own using
the phonetic alphabet (see Table 7 on page 67). For example:
‘Alpha Bravo One, this is Alpha Bravo Two. Do you receive
me? Over.’
66
NGT Transceiver Getting Started Guide
HF radio transmission
In this example your call sign is AB2 and you are calling a
station with the call sign AB1. A call sign is a group of letters
and numbers issued by a government authority to identify a
station. The phonetic alphabet is used to ensure that your call
sign is understood.
The word ‘over’ is used to signify the end of your
transmission. The transceiver may be set up to transmit a short
beep when you release the PTT button on the handset. When
your conversation with the other party is finished, the party
that speaks last should say ‘out’.
Swearing or foul language should not be used—heavy
penalties can apply.
Keep communication as short as possible.
