Motorola Passport radios can be programmed for disabled transmit on certain talkgroups also although they still have to afiliate or register with the system before they will receive the talkgroup regardless on whether or not it was already being carried on that tower or not.
The controller can be set for stun on certain radio ID's or MINS. This is used mostly for seasonal customers or if somebody hasn't been paying their bills. When the radio tries to register with the system it will show as Disabled.
The owner also has the option to turn on ESN validation. If a radio tries to spoof another radio ID with a different ESN then what is programmed into the Home site for that talkgroup, it also shows disabled but I believe it can also be killed depending on how the controller was programmed.
The controller also has the Kill command which is similar to the inhibit command on a Moto Type II system. Not sure if the radio can be revived by reprogramming or if it has to go to the Depot as I never did see one come into our service shop after it had been killed.
If you are looking to passively monitor your local system with a Passport Radio, it can't be done. Your best bet is to park your scanner on the home channel and hope the system isn't too busy.
I would think that the radio itself could be programmed for transmit disable. I know on Kenwood radios, each talkgroup that is programmed in has a setting for transmit disabled or enabled, but I do not know about the other manufacturers.
