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

You cannot transmit if any traffic is

Busy Channel with

detected on the channel.

Carrier

 

 

 

Transmit Inhibit on

You cannot transmit on an active channel

Busy Channel with

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.
