Line controlled
base/mic
Specifies the subtone to be used when the base station transmits audio from the
balanced line input, unbalanced line input, or microphone connected to the
control panel.
Talk through
repeater Specifies the subtone to be used by default when the base station is repeating.
It is only used if the received signal does not have any of the subtones specified
by the signalling profile.
Tx Timers
In the Add or Edit Signalling Profile dialog box, the Tx Timers tab lets you
configure tail timers that the transmitter users.
You can also set up a transmit lockout and enable anti-kerchunking.
Three different tail timers give you power and flexibility in tail timing. The
total tail time is the sum of all three timers. The graphic at the top of the tab
shows the difference between them. Tail timers are used to:
Q
eliminate squelch tail (the ‘tish’ sound caused when the CTCSS detector
doesn’t immediately re-mute the user’s radio when carrier ceases)
Q
prevent users on different subtones from taking control of the repeater
during a temporary lull in the conversation
Transmit lockout
To prevent radio users from monopolising the base station, you can set a time
limit and have the transmitter lock users out for a defined period after this time
limit is exceeded. Transmit lockout terminates the current transmission and
gives other users the opportunity to use the channel.
