When disaster strikes, and conventional communication systems fail, amateur ham radio operators step in to bridge the gap, providing a crucial link between those in affected areas and the outside world.
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.

But if you are not able to be heard, your radio immediately notifies you.
