Digital Scanner
Best thing to do is look at the RR Database for the city(s), county(ies) where you live and/or work. If there are a number of digital systems, then a digital scanner would be the best buy. If there aren't any or only one or two systems (Public Service - City/County) then an analog scanner would do fine for the present. As has already been mentioned in this string - many Cities/Counties are in the process of moving to digital or will be sometime in the next year or two. I don't know if there is a requirement and deadline for all cities/county public service systems to switch to digital and what that deadline is. There may be someone on that will know for sure and can let you/everyone know what that deadline is.
