Common Radio Features
Smart PTT (Conventional Only)
Smart PTT is a per-channel, programmable feature used in
conventional radio systems to keep radio users from talking over
other radio conversations.
When smart PTT is enabled in your radio, you will not be able to
transmit on an active channel. If you try to transmit on an active
smart-PTT channel, you will hear an alert tone, and the transmission
will be inhibited. The LED will also blink red to indicate that the
channel is busy.
Three radio-wide variations of smart PTT are available:
Transmit Inhibit on
Busy Channel with
Carrier
You cannot transmit if any traffic is
detected on the channel.
Transmit Inhibit on
Busy Channel with
Wrong Squelch Code
You cannot transmit on an active channel
with a squelch code or (if secure-
equipped) encryption key other than your
own. If the PL code is the same as yours,
the transmission will not be prevented.
Quick-Key Override This feature can work in conjunction with
either of the two above variations. You
can override the transmit-inhibit state by
quick-keying the radio. In other words,
two PTT Button presses within the
preprogrammed time limit.
