Wideband
This software is made to work and control the wide band
receiver/transmitter boards.
Scan Mode
During programming of the radio, any channel can be
selected as a scanned channel. When a channel is selected as
a scanned channel, it becomes part of the scan list. The scan
list will be activated by switching to the channel that was
selected as the scan channel during programming of the sys-
tem parameters.
The channel that was selected as the scan channel can still be
used as a receive only channel when in scan mode or receive
and transmit channel if the channel has been programmed for
“Priority Scan TX”.
Scan Channel Delete
When the unit is in scan mode the monitor button can be
pushed to delete a channel from the scan list. If the monitor
button is pushed while scanning has stopped to monitor an
active channel, that channel will be deleted from the scan
list. The channel will remain inactive in the scan list until
the scan mode is re-initiated by switching off the scan list
channel and switching back to the scan list channel. Any
number of channels can be deleted from the scan list in this
way. The scan list is always initiated with all the scan list
channels active.
