I would like to purchase one of the many DMR radios offered. My question is whether or not I can get one that works in the 440 Ham band but could also monitor frequencies above 470 Mhz. I'm looking at radios by Connect Systems, Hytera and Vertex (not ruling out Motorola either). Can any of the models do this? I know most commercial radios will have either a 380 to 450 or 450 to 520 split.
