What is IPSC2?

IPSC2 is an independent DMR Master Server connected to the worldwide DMR+ (bMaster+) system. It is often considered the “New DMRplus” network. The IPSC2 system is developed by radio amateurs and offers unique features & connectivity with its IPSC2 servers and bMaster+ worldwide networks. The IPSC2 network is designed for independent DMR networks, with numerous innovative futures connected by bMaster+.

Independence, flexibility & stability are clearly recognised for user’s & sysops of the IPSC2 system. The stability of the IPSC2 network is an integral part that shapes the community of the global DMRplus IPSC2 network.

**Note – The Phoenix Network, (now DV-Scotland), no longer map TG235, 80-84 & regional talkgroups via the DMRplus Reflector system, eg. 4400, 4430 etc. This was a decision made by the Phoenix network (DV-Scotland). IPSC2-FreeSTAR shares all National and Regional talkgroups (that are local to our UK server) to the DMRplus Reflector system as standard. We recognise that some people still activly use the DMRplus Reflector system to connect to their local groups and regional areas.
