About your DMR digital radio

Your DMR digital radio can be programmed for DMR 

conventional or DMR trunked operation. Analog 

conventional and MPT operation is also available.

DMR and MPT trunking operation is controlled 

by a software license (SFE) and may not be 

available with your radio.

In DMR and MPT trunking operation, dual-mode 

networks are able to receive both digital and analog 

calls.

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.
