This code is itself is encrypted with in the digital packet that is sent to the radio with the encrypted audio and channel control data. It would be extremely difficult to decrypt this information which is why it was chosen. The radio is keyed at the start with the callsign, serial number and other data then it is able to be controlled over the air.
Presumeably then if a radio is stolen, the radio can be disabled quickly and easily?

If it's in range and switched on, just reprogram it to die - all over the air.

Yes it can be disabled and reenabled if found at a later date. They also have a button that clears the codes on the radio's so if an officer gets into difficulty it can made useless. If the radio's are dismantled in an attempt to reverse engineer they are also automatically cleared and the radio made useless.

I talked to some detectives from Perth today. We deal with police through our line of work every couple of weeks. Basically as someone stated West Metro is already converted (Scarbourough and suburbs around there) to digital. Around 70% of cars now have tardis installed. Told them about this place didn't mention any names will do that tommorow morning when I see them again tommorow. Might have some new faces. They are top blokes

I don't think it will be audio stream, more like a web based interface mimic of CAD with delay.
