has anyone heard anything about this? i was told the police depts are going to start using this new encryption that can't be heard by any scanners on the market today.
You can download DSD, using your scanner you can decode the digital format on your computer.
Here is an entire thread talking about it: http://forums.radioreference.com/digital-voice-decoding-software/
Look at the third sticky for the Windows port version, this should be a good start for you.
Just to clarify, TRBO isn't encryption it is a digital format.
You would also need a discriminator tap in your radio to drive the software...I'm curious specifically what departments are thinking of going MotoTRBO?
