The only things I know is what has been posted, either in various threads here, or over on the DFWScan group.
The way I understand it, at this point (which may or may not be 100% correct, and of course is subject to change) is that FWFD will not be encrypted. Last thing I saw was that some of the smaller jurisdictions, such as North Richland Hills, Haltom City, etc, were leaning against encryption, but no final decision. I have not seen any specific comments on TCSO; if there have been some, I missed them.
