I have a new TRX-1 and I'm listening to Fluvanna Co Virginia. And when there's a transmission on the Sheriff's Dispatch talk group, I do get a few words here and there and then I also get a busy signal like on a telephone. The "E" on my scanner doesn't show up. They just upgraded the county's system to P25 Phase II, do I have to do anything special on my scanner to tell it, it's P-II? All other talk groups are fine. Is this possibly encrypted? I've heard other encrypted signals on other systems and they sound garbled, unintelligible, and the "E" does show on my scanner, but not on this site.
