We will know by Monday if it actually happens. It would require a massive logistical effort as every radio would have to be touched to load the new programming, and every site configured. Certainly needed to have been planned way before November of last year.
True but experience I've had and people I talk to say that all police radios, regardless of agency, have encryption already loaded when they are programmed. They can just choose to not use it as it is a matter of flipping the switch.
There is 1 Town in Sussex (Georgetown) and 1 Fire Department (not sure the name at this time) that have full time encrypted talk channels.
Rehoboth has a clear Dispatch Channel but 2 full time encrypted talk channels. In my experience having worked for police agencies they have it programmed in, just can choose to not use it.
Even the Courts have Encryption, but again don't use it. The radios are programmed with it so if a radio with encryption on is talking to one with it off it can still send/receive to that radio. It's just designed that way.
I hope that helps.
