as Mark said, all of Plymouth County and Boston are conventional analog, except for Mass State Police. That is trunked, which your scanner will have no trouble with. Just a heads up, Boston Fire is now using a new system so you won't hear them dispatched to every call, expect for fires.The 346XT will be more than enough. I have a Freescan file for Plymouth County and most of eastern MA if you want me to send it to you? PM me, thanks.
