Digital mobile radio (DMR) is an open digital mobile radio standard defined in the European Telecommunications Standards Institute (ETSI) Standard TS 102 361 parts 1–4[1] and used in commercial products around the world. DMR, along with P25 phase II and NXDNare the main competitor technologies in achieving 6.25 kHz equivalent bandwidth using the proprietary AMBE+2 vocoder. DMR and P25 II both use two-slot TDMA in a 12.5 kHz channel, while NXDN uses discrete 6.25 kHz channels using frequency division. The standard has become popular within the amateur radio community due to the relative lower cost and complexity compared to other commercial digital modes.

DMR was designed with three tiers. DMR tiers I and II (conventional) were first published in 2005, and DMR III (Trunked version) was published in 2012, with manufacturers producing products within a few years of each publication.

The primary goal of the standard is to specify a digital system with low complexity, low cost and interoperability across brands, so radio communications purchasers are not locked into a proprietary solution. In practice, many brands have not adhered to this open standard and have introduced proprietary features that make their product offerings non-interoperable.

Some people have been asking about how the TG8 works on VKDMR network below 8/X full talkgroups the the repeators they link with.

Radio Programing for use with you loacl repeaters all you need the programe Talkgroup 8 on Timeslot 1 into your radio to access your group of repeaters but in you want to go to a deffrent area this where u need to differ the programing with the flowing talkgroups
Area Number TG8 Area Repeaters Full talkgroup
1 – VK7 Launceston, Hobart 10008 
2 – Sydney, W and N NSW All Sydney, Orange and Grafton 20008 
3 – Southern VK2 and VK1 Highrange, Goulburn, Yass and Canberra 30008 
4 - Mt Wombat and Shepparton Mt Wombat and Shepparton 40008
5 – VK3 VK3 50008
6 – SE Queensland Brisbane and SE Qld 60008
8 – VK5 Adelaide 80008
9 – Perth Perth 90008

Acording the the VKDMR web site these talkgroups cant be canged i have a duplex hotspot configured with 8/2 and it a static talkgroup in my hotspot but i have also found my grabing a handheld and manually setting the talk group in the right hand colum on the table 8/6 i can also come out on the Brisbane and SE Qld repeaters at the of writeing this futher testing is need to see im i can hear the 8/6 or anyone the others areas i will update this as i do some testing.

IPSC2 options = TS1_1=X0008; MMDVM repeators and pistar duplex Hotspots.

Something for simplex hotspot users you may not want to static it in the options in the options line so i would just progame the full talkgroup into your radios (example for the ALL Sydney,Orange and Grafton progeame talkgroup 20008 into your radio) i know this works as i have done sometesting
