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:
eliminate squelch tail (the 'tish' sound caused when the CTCSS detector
doesn't immediately re-mute the user's radio when carrier ceases)
prevent users on different
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 call and gives other
users the opportunity to use the channel.
In the Add or Edit Signalling Profile dialog box, Tx Timers tab, the Transmit
lockout check box enables the temporary disabling of the transmitter after a
call that exceeded the time limit.
The Transmit timer box specifies the time limit for calls. If a call exceeds the
time limit, the transmitter is locked out and the call cannot continue. The
transmitter is unable to transmit for the length of time specified in the Lockout
duration box.
Anti-kerchunking
Anti-kerchunking discourages radio users from repeatedly pressing PTT briefly
to ascertain whether they have service or to reserve the base station for
themselves.
