Eh, they've been using VIPER and analog radio together since the VIPER towers were installed. As a lifetime Asheboro resident and feed provider, I was excited and very confused when I saw this on TV, but then I was like "this isn't news at all"... I'm not certain why they did a story over a year after they started using 800Mhz digital. I'm guessing they will get more talkgroups, b/c I think all the cities' police in Randolph use a single talkgroup right now.
I don't believe so. They may decide to encrypt one or more Tactical talkgroups, but judging from Randolph's lack of encryption so far I think it's likely they won't. Plus it's all about interoperabililty, no?
