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. 

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.

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.
