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).

DMR Repeaters in Essex

DMR in Essex seems to be growing quickly.  There are DMR repeaters across Essex, Kent, Suffolk and East London, including:

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
TG810 South-East England Group of local repeaters for Essex, Kent, Hertfordshire and East London (See list)
TG840  East England Group of local repeatersfor the East of England  (See list)
TG235 UK-Wide UK-wide Calling. Opens all repeaters.
Once contact made, switch to TG80 or TG81
TG80 to TG84 UK-Wide (User) “User Activated”, so doesn’t open all repeaters. Use if you want to chat with someone else in the UK
TG2 Europe Europe-wide Calling. Use for a short time to establish contact, to avoid tying up the group
TG13 Worldwide English World-wide Calling for English-speakers. Use for a short time to establish contact, to avoid tying up the group.

DMR Radios

We’re happy to recommend the Tytera MD-380 – A DMR-enabled handheld at a decent price. Here are some handy links

  • TYT MD-380 Review – Thanks to Paul G7BHE for the review
  • Buy a TYT MD-380 from eBay
  • Ham Goodies DMR Codeplug – programming any DMR radio can be a pain. Save some time and use the excellent codeplugs created by Charlie M0PZT – There’s a UK-wide one, or one that includes the local repeaters. Download the file and upload to the handset via a PC USB cable
