DMR In Essex

On this page, you’ll find some basic information about DMR, and some handy information for those in and around Essex.

What is DMR?

DMR is a Digital Voice mode. There are three Digital Voice modes currently: DMR (Motorola), D-Star (Icom) and Fusion (Yaesu).

DMR is gaining ground, and price may play a part in this. Handsets, such as the Tytera MD-380 are now around £100 (much cheaper than a D-Star).

Talk Groups

DMR repeaters are configured to allow access to selected “Talk Groups”. As a repeater can only have two slots, only two of these can be used at any one time.

The following list shows the main groups for us in Essex, sorted by distance:

 

Group Description Notes
TG9 LOCAL Local repeater – So much like an analogue repeater, only those listening locally can send/receive. Use slot 2 where possible
TG801 South-East England Group of local repeaters for Essex, Kent, Hertfordshire and East London (See list)
TG840  East England Group of local repeaters for the East of England  (See list)
