About your DMR digital radio
Your DMR digital radio can be programmed for DMR
conventional or DMR trunked operation. Analog
conventional and MPT operations are also available.
You may notice differences between digital and
analog calls in terms of:
■
static noise in low signal areas, and
■
radio coverage in marginal reception areas.
Lack of static noise
On digital networks there is no static noise, even in
low signal areas. This lack of static is because your
digital radio removes the ‘noise’ from the call, so that
you hear only clear voice.
Coverage
With digital networks, a call remains clear and then
drops off quickly at the border of a coverage area. The
reason for this is that a digital call is either received or
it isn't. With analog networks, the background noise in
a call gets progressively worse when you are in fringe
areas or even slightly outside normal coverage areas.
