Oh yeah, there are modes like DMR and YSF that are completely digital data. That really helps a lot because with analog, the further you got away from the repeater you are using, the scratchier your voice would become until you just weren't understandable. With digital, you either make the system or you don't. There's no real in-between. You're either able to be heard or you're not. But if you are not able to be heard, your radio immediately notifies you.
