Digital?
No, Frederick County has no plans that I've heard of to go digital anytime in the near future (say, 5 years). There is always talk of it, but that's about it. There are also some in Frederick County who believe the 800 trunk system we currently use is "digital" and incapable of being monitored by the public. I've heard them say that, and then, of course, word gets around that we either already "are" digital, or are going that way.
FYI, the county just upgraded all of it's police and fire radios within the past 2 years. That includes new towers in various locations. I don't see them footing the $$$ right now to upgrade the system yet again to digital.
As for Frederick City, they are NOT digital, merely encrypted APCO 25 on the old channels they'd previously used. They may switch back to plain, or they may not, it just depends on high level type decisions there.
So, the answer is, no, unless you want to spend the money on the digital scanner to listen outside the county, Frederick is safe for now. As is, by the way, Carroll County, which between the 2, keeps me plenty busy. I can get both, for the most part (Carroll can get spotty in places) with my rubber duckie antenna on my RS PRO 94.
