Structure of user information
Information in the Envoy™ Transceiver is stored like blocks in a building. Basic
blocks are populated with information first, then these blocks, along with different
blocks, are assembled into larger blocks. Ultimately, one of the top-level blocks is
used to make a call.
The most basic block is a frequency. A frequency is combined with a mode, say USB
or LSB, and a name to become a channel. Channels may be grouped into scan tables.
Scan tables may be allocated to HF networks. An HF network defines the call system
by which a call is made.
Further blocks may be assembled for the convenience of the user. A contact stores
information on the typical calls that can be made to a person. Each call is defined by
the HF network and the call type.
How these blocks are assembled is up to the system administrator. There is, of course,
finer detail that needs to be included, however, the basic structure of information in
the transceiver is shown in Figure 25.
