Certainly all of those are DNR frequencies, and there have been reports of P25 usage on DNR frequencies in the past year or more. I can tell you that I still hear plenty of analog transmissions on the DNR frequencies that I listen to in the Upstate, including Spartanburg and Caesars Head. I have each of those programmed into the scanners at P25 channels and haven't heard much at all in that mode, but maybe I've just missed it. Maybe others can chime in on what they've heard.
A digital scanner should allow you to listen to those channels assuming they're not encrypted - if they are encrypted, that might be why I'm not hearing them.
