Transceiver
The Transceiver window displays the selected
Transceiver (TCVR) alpha identity (A to F if a
six-way Interswitch is connected, see
Interswitch), its status (Master or Slave) and
the scanner unit the transceiver is connected to
(X-band or S-band).
The following controls are available when
operating as a Master display:

switching the operational mode between
standby and transmit

changing the pulse length

changing between AFC and manual
tuning
If the Transceiver has been selected as a Slave
at the Interswitch window the Pulse Length and
Tune functions are unavailable.
Operational Mode
The system can be in one of two operational
modes: Standby and Transmit. In addition, when the system is in standby
following power up it may also be warming up
48
.
A slave display can only be switched to Transmit if its associated
master display is in Transmit mode. If Transmit is selected on a
slave display when its master is still in Standby (NOT transmitting),
a prompt is displayed and the slave remains in Standby.
48
Upon power-on of a “cold” transceiver, a warm up period is required to prevent damage to
the magnetron before it can start transmitting.
The transceiver informs its connected display(s) if it is in the warm up process.
When a display is connected to a transceiver that is in warm up, either because of
interswitching or from power-on, a textual status and a count appears in the Transceiver sub
menu. The count starts at 0 and increment each second up to a maximum of 999. Only when
the transceiver informs the connected display(s) that the warm up period has ended is the
text and count removed and the normal standby text displayed. Transmit can be selected
only when the warm up period has ended.
