DC PD 460MHz simulcast system (site) is now fully encrypted except for one talkgroup CW-1.
The FD 800MHz system (site) isnt and talkgroup CW-1 is simulcast on 800 so you realy only need to worry about one system any more.
I doubt it will depricated in the RRDB yet, since its still active. It will be replaced in about a year with something new (also fully encrypted.)
I would expect to see most of the surrounding jurisdictions to do a lot of encryption in the next 2-5 years also.
