Audio tab of the Programmable I/O form.
27.2.1 Repeater Transmit Tail Settings
TM8100 Radios
If the transmitter requires a “tail”, then this can be set in the External
PTT (1) tab of the PTT form. During the PTT deactivation delay period,
any signalling, such as CTCSS or DCS, is still present.
If a further transmitter tail is required, then this can be configured in the
Subaudible Signalling tab of the Basic Settings form. During the lead-out
delay period, no signalling, such as CTCSS or DCS, is present.
TM8200 Radios
If the transmitter requires a “tail”, then this can be configured in the
Subaudible Signalling tab of the Basic Settings form. During the lead-out
delay period, no signalling, such as CTCSS or DCS, is present.
