About your digital radio
You may notice some differences in the way digital and
analog radios perform: the lack of static in low signal
areas and consequently where you notice that coverage
is poor.
Lack of static noise
You may notice the lack of static noise on digital
channels. This lack of static is because your digital radio
removes the “noise” from the transmission so that you
hear only clear voice.
Coverage
With analog radios, a transmission gets progressively
worse when you are in fringe areas or even slightly
outside normal coverage areas. In these circumstances,
you are probably able to still understand the
transmission despite the amount of static because the
human brain can interpret speech even when it is not
perfectly clear.
With digital radios, the signal remains clear and then
drops off quite quickly at the border of a transmission
area. The reason for this is that a digital transmission is
either received or it isn't.
Because of this difference you may notice that digital
radios have different coverage patterns to analog
radios. However, the actual coverage area between an
analog and a digital voice system is very similar.
