Means...
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 a station
ID, or a self ID.
An ALE broadcast call that is made from your transceiver on the channels
in the scan table(s) allocated to the HF network that is selected for the call.
Stations that detect the call update the relevant information in their LQA
database.
ALE Sounding calls are available if the MIL-STD-188-141B ALE option
is installed.
An ALE address syntax used to broadcast to any station that is tuned to or
scanning the same frequency in an ALE/CALM HF network. The ALL
call uses a special address syntax @?@ that ALE stations recognise.
A selective ALL call addresses a subset of stations. A multiple selective
ALL call addresses these subsets within the one call.
The global ALL address syntax may be used if the FED-STD-1045
ALE/CALM option is installed. Selective ALL calls may be made if the
MIL-STD-188-141B ALE option is installed.
An ALE address syntax used to broadcast to any station that is tuned to or
scanning the same frequency in an ALE/CALM HF network. The ANY
call uses a special address syntax @@? that ALE stations recognise.
A selective ANY call addresses a subset of stations. A multiple selective
ANY call addresses these subsets within the one call.
The ANY address syntax may be used if the MIL-STD-188-141B ALE
option is installed.
A process that automatically adjusts the gain with respect to the input
signal to provide a constant output level.
A process that automatically provides a constant output level as the input
level varies.
An antenna designed for use with multi-channel transceivers. It transforms
the frequency-dependent load presented by the antenna to a stable
impedance close to 50 Ω to enable the transmitter to operate efficiently.
The station that receives the call. You enter the address of this station, or
an appropriate syntax to match the address, when you make a call to this
station.
