Appendix F—HF radio transmission 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.
NGT SRx Transceiver Getting Started Guide
61
HF radio transmission
Sky wave The sky wave is the most important form of HF propagation. The HF 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 5:
The reflective properties of the ionosphere
ionosphere
emitted HF radio wave
reflected HF radio wave
receiver
transmitter
Frequency, distance and time of day The extent to which an HF 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.
62
NGT SRx Transceiver Getting Started Guide
HF radio transmission
Summer HF radio communications usually operate on higher frequencies than those used in winter over the same distance. 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 radio communications 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, for example, ‘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 7 shows examples of channels and the information associated with them. Table 7:

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 radio communications 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 scanning is switched on when you are not using the transceiver to communicate. This ensures that you can receive calls from stations in your HF radio communications network.

HF radio transmission
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 8 on page 66). 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. 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.

active line
The line below the title of a list on the handset screen. Items in the active line are selected by pressing .
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.
automatic tuning An antenna designed for use with multiantenna channel transceivers. It uses a microcontrolled stepper motor to give continuous tuning over the operating frequency range of the antenna. call detect time The length of time during scanning that the transceiver pauses on each channel in order to detect an incoming call. It is the inverse of the scan rate. channel
Frequencies programmed in the transceiver to transmit and receive signals on air.
Channel Test call
A call that enables you to test the quality of a channel in a Codan Selcall network.
control cable
A cable connecting two items of equipment that allows control information to be passed between the equipment.
