If the Cfg LBT Mode in the Control List is enabled, the transceiver will detect whether or not there is traffic on the selected channel, i.e. the channel is occupied. The transceiver will listen on a channel for the length of time specified in the Cfg LBT Period entry in the Control List. The transceiver will try busy channels twice before reporting that they are busy.The Cfg LBT Mode may be set to Enabled, Override allowed, or Disabled.When the Cfg LBT Mode is set to Enabled, and the transceiver detects that the channel(s) tried is(are) busy, it will prompt you to try the call again. You can:• press the key to try the call again using LBT• press the key to select a new channel, then press the key to make a call on this channel using LBTNOTEIf you change the setting in the Cfg LBT Mode entry in the Control List you must switch the transceiver off then on again for the change to take effect.NOTEIf only one channel was tried and found to be busy using LBT, you can listen for traffic on the channel then, if clear, override LBT by holding the key.

NGT ASR Transceiver Getting Started Guide 73CODANAppendix E—HF radio transmissionThe 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 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 waveGround waveThe 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 waveThe direct wave travels in a direct line-of-sight from the transmitter to the receiver.
HF radio transmission74 NGT ASR Transceiver Getting Started GuideSky waveThe 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.Figure 7: The reflective properties of the ionosphereFrequency, distance and time of dayThe 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.ionospheretransmitter receiveremittedHF wavereflectedHF wave
HF radio transmissionNGT ASR Transceiver Getting Started Guide 75Solar 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 frequencyChannels and modesA 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.Table 6: Examples of channels and modesChannel Receive frequency(kHz)Transmit frequency(kHz)ModesChannel 1 10600 10600 LSB, USB4500 4500 – AMHeadquarters 22758 23000 USB
HF radio transmission76 NGT ASR Transceiver Getting Started GuideNetworks and scanningA 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 optionThe 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.
HF radio transmissionNGT ASR Transceiver Getting Started Guide 77The Advanced ALE optionsThe 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 radioThere 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. 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.NOTEIf you have the Cfg LBT Mode set to Enabled or Override allowed, the transceiver searches for a channel that is not being used; you do not need to check any channels first.
HF radio transmission78 NGT ASR Transceiver Getting Started GuideThe 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.Table 7: The phonetic alphabetLetter Word Letter WordA Alpha N NovemberB Bravo O OscarCCharliePPapaD Delta Q QuebecEEchoRRomeoF Foxtrot S SierraG Golf T TangoHHotelUUniformI India V VictorJ Juliet W WhiskeyK Kilo X X-rayLLimaYYankeeM Mike Z Zulu

DefinitionsNGT ASR Transceiver Getting Started Guide 81GlossaryThis term Means...active line The line below the title of a list on the handset screen. Items in the active line are selected by pressing the key.address The HF transceiver equivalent of a telephone number. Your station self address is used by other stations to call you, and it is sent when you make calls to identify you as the caller. It is sometimes referred to as an ID, a station ID, or a self ID.ALL call An ALE address syntax used to broadcast to any station that is tuned to the same frequency in an ALE/CALM network or scanning the network. The ALL call uses a special address syntax @?@ that ALE stations recognise. The ALL call does not request any automatic responses from stations that enter the link. Stations can be configured to enter a link on detecting an ALL call or to ignore an ALL call.A selective ALL call addresses a subset of stations tuned to the same frequency in an ALE/CALM network or scanning the network.A multiple selective ALL call addresses these subsets within the one call.
Definitions82 NGT ASR Transceiver Getting Started GuideANY call An ALE address syntax used to broadcast to any station that is tuned to the same frequency in an ALE/CALM network or scanning the network. The ANY call uses a special address syntax @@? that ALE stations recognise. The ANY call requests an automatic response from stations detecting the call. These responses are returned in any slot position (collisions may occur). The initiating station then completes the link establishment with an acknowledgement sent to all stations from which it received a response. The operator at the initiating station can use these responses to gather information on the status of the stations using the network. Stations can be configured to respond to or to ignore ANY calls.A selective ANY call addresses a subset of stations tuned to the same frequency in an ALE/CALM network or scanning the network.A multiple selective ANY call addresses these subsets within the one call.automatic tuning antennaAn antenna designed for use with multichannel transceivers. It uses a microcontrolled stepper motor to give continuous tuning over the operating frequency range of the antenna.channel Frequencies programmed in the transceiver to transmit and receive signals on air.This term Means...
DefinitionsNGT ASR Transceiver Getting Started Guide 83Channel Test callA call that enables you to test the quality of a channel. It is sometimes referred to as a Beacon call. Channel Test calls may be made in an ALE/CALM network to replace information in the LQA database, and to perform a manual sounding operation.control cable A cable connecting two items of equipment that allows control information to be passed between the equipment.Emergency call A call that enables you to trigger an emergency alarm at a specific station then speak to an operator there.fixed base stationA transceiver that is permanently installed and cannot be moved without significant effort. It consists of a transceiver, a transceiver supply, an antenna, control and accessory devices, ancillary equipment, and appropriate connecting cables.frequency The number of cycles per second of a radio wave, usually expressed in kilohertz.Get Position call A call that gets the GPS position of a specific station.Get Status call A call that gets diagnostic information about the transceiver at a specific station.This term Means...
Definitions84 NGT ASR Transceiver Getting Started GuideGroup Selective callAn ALE call that is sent to stations specifically addressed in the call that are tuned to the same frequency in an ALE/CALM network or scanning the network. The Group Selective call requests an automatic response from stations that detect the call. These responses are returned in reverse order from that provided in the call. The initiating station then completes the link establishment by sending an acknowledgement to all stations from which it received a response.handset A hand-held device that is used to control the functions of a transceiver. It consists of a microphone, PTT button, display and keypad.hot key A key on the handset or desk console that is pre-programmed with a macro that enables you to perform a task quickly.junction box The unit in a transceiver to which a handset, RF unit, speaker and related devices are connected. The junction box receives the instructions that a user enters through the handset and sends these instructions to the relevant devices.Last Heard Log A log of the last 100 on-air transmissions detected by the current station. The information gathered from each transmission includes the self address of the heard station, the time/date of the transmission, and the channel/mode used for the transmission.This term Means...
DefinitionsNGT ASR Transceiver Getting Started Guide 85link A link is established following a 3-way handshake process. Scanning is off and a timeout, set using the Cfg In Call Timeout entry in the Control List, will be active.With ALL calls and NET calls that are set to link immediately, the linking establishment process is 1-way.listen before transmitIf enabled, the automatic process that the transceiver uses to detect whether or not there is traffic on a channel and, when necessary, select another channel or inform the user that the channel is busy.LQA beacon A Channel Test call made in an ALE/CALM network using a Group Selective or NET address syntax. The LQA beacon tests all channels within the network to determine the best channel according to local and remote BER and SINAD measurements. On completion of the beacon, the information collected replaces the information for the channel stored in the LQA database. It is sometimes referred to as an ALE beacon.macro A short set of instructions to automate a task you perform with the transceiver. When a macro is assigned to a key, the key becomes a hot key.manual sounding A Channel Test call made in an ALE/CALM network using the text SOUNDING as the call address. The station performs a sounding operation, which other stations use to update the information in their LQA database.Message call A call that enables you to send a message to a specific station.This term Means...
Definitions86 NGT ASR Transceiver Getting Started Guidemobile station A station that is usually mounted in a vehicle or is portable and easily transportable. It consists of a transceiver, a power supply, an antenna, control and accessory devices, ancillary equipment, and appropriate connecting cables.mode A type of reception or transmission you can use with a channel e.g. USB.NET call An ALE address syntax that is used to send a call from one station to other stations that have the NET programmed in the NET List. If these stations have their self address in the Member Address setting they become members of this NET. The member stations send an automatic response to the initiating station in a pre-determined response slot, if enabled to do so. The initiating station then completes the link establishment with all member stations. Any other stations with the NET programmed will enter the link at this time too.network Two or more stations that use the same frequencies and call system to communicate.Phone call A call that enables you to connect to a public telephone network.PTT button Press-to-talk button, located on the left side of the handset. This button enables you to communicate during voice calls, switch mute off, cancel voice calls prior to the point where voice can be transmitted, cancel calls where data is being transmitted, and exit out of editable screens without saving changes.This term Means...
