About your DMR digital radio
Your digital radio may be programmed for DMR (digital)
trunking, MPT (analog) trunking, or both (dual mode).
Dual mode networks are able to receive both digital and
analog calls. Fully-featured conventional analog
operation is also available.
You may notice differences between analog and digital
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 analog networks, the background noise in a call
gets progressively worse when you are in fringe areas or
even slightly outside normal coverage areas. 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.
