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 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
CODAN
Ground wave
The ground wave travels near the ground for short distances,
typically up to 100 km over land and 300 km 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.
NGT ASR Transceiver Getting Started Guide73
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.

74NGT ASR Transceiver Getting Started Guide
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.
Tabl e 6 shows examples of channels and the information
associated with them.

HF radio transmission
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
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.
The CALM option
The NGT ASR transceiver has the CALM option installed as
standard. CALM stands for Codan Automated Link
Management.
The CALM option enables the transceiver to test the signal
propagation qualities of your channels and build a profile of
each channel’s suitability for use at different times of the day
and night. The transceiver can then select the most suitable
channel/mode for you when you make a call. You are able to
make ALE ALL calls with this option.
CALM is compatible with FED-STD-1045 ALE.
76NGT ASR Transceiver Getting Started Guide
The Advanced ALE options
The Advanced ALE options are installed in addition to the
CALM option, and are standard for the NGT ASR transceiver.
They provide the capability to make ALE calls using ALL,
ANY, Group Selective, NET and Wildcard address syntaxes.
These calls are from one station to many stations at the same
time. The Advanced ALE options also provide advanced link
quality analysis and advanced messaging.
The Advanced ALE options are interoperable with
FED-STD-1045 ALE and MIL-STD-188-141B.
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 the PTT button 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.
HF radio transmission
If you have the Cfg LBT Mode set to Enabled or
NOTE
Override allowed, the transceiver searches for a
channel that is not being used; you do not need
to check any channels first.
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 78). For example:
‘Alpha Bravo One, this is Alpha Bravo Two. Do you receive
me? Over.’
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.
NGT ASR Transceiver Getting Started Guide77
HF radio transmission
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.
