Crossband Repeater Settings
The following settings are for cross-band repeater operation only. These
settings require a cross-band linking cable to be installed between the radio’s
auxiliary ports. For more information, see
“Installing a Cross-band Linking
Your cable may have additional connections that require further pro-
gramming (for example, GPS, ignition sense, and external alert). For
information on settings related to these additional connectors, refer to
the installation instructions for your cable (see
), or contact your radio provider.
Programmable I/O
and Audio Settings
At a minimum, settings in
must be
programmed for both radios.
Notes:
1.
Select Busy Status (
) to re-
transmit any signal.
2.
Select Signalling Audio Mute Status (
) to transmit valid signalling only. This is
recommended if the repeater is to operate on a scan group where
member channels require valid subaudible signalling. Otherwise the
radio may re-transmit short bursts of activity when a channel is busy
but not captured due to invalid activity.
3.
D-Split means the receiving radio will sound the repeater audio. To
silence the repeater signal on the receiving radio, select C-Bypass
Out.
