The FreeDMR Server.
The new system is derived from HBlink and is fully-open source and available on GitHUB. The server software allows the implementation of features as we would like to see them, making the software completely customisable to your needs. This also allows the response to issues and bugs more effectively. This system is bridged to other Servers, providing a frontend system with enhanced functionality. It also enabled repeaters to be able to communicate even if a Server upstream is down. An overview of the added functionality is below. Note, all of this functionality is optional and configurable.

Enhanced Talkgroups (dial-a-tg)
Implementation of an enhanced version of a low level talkgroup, including all of the voice announcements, timeouts etc. The confusing numbering used for the old reflector system (TG9) is obsolete. Instead, you can simply manual-dial a private-call to any talk group number to have it routed to Talk Group 9 on Time Slot 2 on a FreeDMR repeater. This also works on Hotspots if you decide to use it. There is control of the timer and fallback to the default Talkgroup (Reflector) as before. Another abbreviation of a Enhanced Talkgroups or Reflectors as they were known is “Dial-a-TG”.
Only allows a single Talk Group to be routed to a Time Slot on a repeater at one time, whilst the Time Slot is active. Even if several static Talkgroups are set up on the slot. As soon as a Talkgroup is keyed up, only that single Talkgroup is routed to the Time Slot until either the timer expires or another Talkgroup is keyed up, which then replaces the first one. This is similar to Hotspot behaviour on other networks. This works even between Dial-a-TG (Talkgroup 9) and other TalkGroups.
Optionally, (set in Options) a 15 minute voice ident in DMR can be set on Time Slot 2. The repeater’s or hotspot call-sign is (spoken) “sent” via “All Call” for optional voice ident. “This is CALL-SIGN FreeDMR”
Things it doesn’t do.
Currently we have not implemented:
- Private calls that transit the network (PC on the current repeater still works)
- Data calls, including SMS and GPS updates (these are a type of PC) – again, still works on the same repeater
