Appendix E—HF radio transmission CODAN 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 and more are possible.
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.
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.
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.
HF radio transmission 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.
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.
