OVERVIEW OF HF NETWORKS
140 ENVOY™ TRANSCEIVER REFERENCE MANUAL
Overview of HF networks
An HF network is two or more stations that use common channel/mode combinations
and call system to communicate. This simplifies communication because each station
knows the method with which they can make and scan for incoming calls, and the
frequencies they can use. To access information about the HF networks programmed
in the transceiver, navigate to User Data > HF Networks.
HF networks are based on call systems. A call system is a method of making and
receiving calls. For example, if you are in an HF network that uses the Codan Selcall
or Open Selcall call system, you make calls by entering the address of the station that
you want to call, then selecting the channel/mode that you want to use. When your call
is detected by the called station, that station rings to alert the operator. In an
ALE/CALM HF network, you make calls by entering the address of the station that
you want to call. The transceiver selects the best channel on which to make the call.
When you add an HF network, you must select the call system that you want to use
and enter the self address. You can then enter further information based on your
selection.
NOTE: The call systems from which you can select depend on the options
installed in the transceiver.
The transceiver can be set to scan the scan tables associated with your HF 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 communication network.
Figure 42 shows the information that is stored for an HF network. Each item is
described in detail in the sections following.
