Encryption can be implemented on a per radio basis as well as per talkgroup. I think you will find the agencies you mention will use encryption in a limited way as and when its needed, quite possibly custom programming radios for specific operations. Examples would be raids on Meth Labs & joint operations with Police (such as those recently involving the bikie gangs). These are cases where encryption is necessary but for every day operations the information gained from listening is not of much value to most crims. I'm also speaking from my own opinion and not on behalf of my agency as they may have different ideas. Encryption keys are a big job to maintain properly, even with OTAR and a team of techs. To me there is little point implementing encryption half cocked, but then an issue like this may end up being managed centrally on behalf of the agencies... I don't think the idea of moving technical support in to a common group or even outsourcing it is beyond the realms of possibility.centralcoastscanman wrote: I'm thinking NSWFB will probly have some channels encrypted as will NSWAS but their general duties will remain digital in the clear...
Railcorp might have their BAS and their CNI Security channel encrypted..
I am only guessing here as to what will happen, and have no inside knowledge of any kind what so ever..
