MASTER SCAN Mode
MASTER SCAN is the default scan mode and is enabled to allow
continual communication across congested channels.
Master Scan scans channels stored into GS Memory and only opens the
squelch for signals with the correct subcode (CTCSS or DCS tone).
To achieve this, all radios in your group must have the same channels
in GS memory (group channels) and use the same Subcode (CTCSS or
DCS tone).
By scanning only group channels, radios in the network will be able to
detect and receive group transmissions- continual communication with-
out interruption. When transmitting in this mode, the radio switches to
an unused group channel if it detects another signal with no code, or the
wrong code, on the channel last used by the group. In this way, all group
users will be able to have continual communication to or from other
users.
CH09-CH20 are stored into GS Memory and CTCSS01 is set for
MASTER SCAN Subcode by default. The GS memory can be changed,
