an active channel. Three radio-wide variations of smart PTT are available:

1.Transmit Inhibit on Busy Channel: With this feature enabled, you will be inhibited from transmitting if any activity is detected on the channel.

2.Transmit Inhibit on Busy Channel with Wrong Squelch Code: With this feature enabled, you will be inhibited from transmitting on an active channel with a squelch code other than your own. If the squelch code is the same as yours, the transmission will not be inhibited.

3.Quick-Key Override: This feature can work in conjunction with variation one or two. With this feature enabled, you will be able to override the transmit inhibit state by quick-keying (two PTT activations within one second of each other) the radio.

Smart PTT radio operation is exactly the same as standard radio op- eration, except that if you try to transmit (press PTT) on a Smart PTT channel, a continuous alert tone is generated until the PTT is released; the transmission is inhibited.
