ENVOY™ TRANSCEIVER REFERENCE MANUAL 463
Group Selective call An ALE call that is sent to stations specifically addressed in the call that
are tuned to or scanning the same frequency in an ALE/CALM HF
network.
The Group Selective call may be used if the MIL-STD-188-141B ALE
option is installed.
handset A hand-held device that is used to control the functions of a transceiver. It
consists of a microphone, PTT button, display and keypad.
HF network Two or more stations that use the same channels and call system to
communicate.
hot key A key on the handset or desk console that is pre-programmed with a macro
that enables you to perform a task quickly.
Last Heard log A log of the last 100 on-air transmissions detected by the current station.
The information gathered from each transmission includes the address of
the heard station, the time/date of the transmission, and the channel/mode
used for the transmission.
The Last Heard Log is available if the MIL-STD-188-141B ALE option is
installed.
link A link is established following a 3-way handshake process. Scanning is off
and a timeout is active (Settings > Calling > General > In Call
Timeout).
With ALL calls and NET calls that are set to link immediately, the link
establishment process is 1-way.
listen before transmit
(LBT)
The automatic process that the transceiver uses to detect whether or not
there is traffic on a channel and, when necessary, select another channel or
inform the user that the channel is busy.
LQA beacon A Channel Test call that is made in an ALE/CALM HF network using a
Group Selective or NET address syntax. The LQA beacon tests all
channels in the scan table(s) associated with the HF network to determine
the best channel according to local and remote BER and SINAD
measurements. On completion of the beacon, the information collected
replaces the information for the channel stored in the LQA database. It is
sometimes referred to as an ALE beacon.
The LQA beacon is available if the MIL-STD-188-141B ALE option is
installed.
macro A short set of instructions to automate a task you perform with the
transceiver. When a macro is assigned to a key, the key becomes a hot key.
Message call A call that enables you to send a message to a specific station.
