134 Part F: Configuring Channels
The Duration box specifies the length of the tone burst. You can specify this
in milliseconds or in cycles. If the burst has too many cycles, it comes back into
phase with the original subtone and the radio may detect it again, re-opening
the receiver gate. Specifying the duration in cycles for different CTCSS
frequencies can help prevent this.
The Phase angle box specifies the amount that the burst is out of phase with
the original CTCSS subtone. If you select +120 or -120 instead of 180, more
cycles are required before the burst comes back in phase with the original
subtone.
Soft-off time
The base station can also send only carrier (carrier without modulation of any
kind) at the very end of each transmission.
In the Edit Signalling Profile dialog box, Tx Timers tab, the Soft-off time
check box enables the feature and the Duration box specifies the length of time
that only carrier is transmitted.

In the Add or Edit Signalling Profile dialog box, the Advanced tab lets you

repeater. They are tones that can be added to transmissions for a particular talk
group. To enable them, edit the Subaudible Signalling tab.
