DCI MotoTRBO IPSC Amateur Radio Group
Our mission is to connect to and converse with the wider DMR Ham community by openly sharing our network resources and talkgroups to enable dynamic connections to all radio amateur DMR groups.

Our focus is to learn more about and experiment with, IPSC, c-Bridge implementation and 3rd party networking options compatible with MotoTRBO IPSC networking.  You only need a DMR capable user radio but you must use or have access to a Motorola MotoTRBO repeater.

Our main pursuits are to actively to participate in the growth of the Amateur DMR community generally and MotoTRBO networking more specifically, to learn more about the "c-Bridge" and promote linking via the c-Bridge and other 3rd party efforts that can expand the abilities of TRBO.  Independent network growth is very simply implemented with the c-Bridge as it is so very easy to do and undo, without the need for the authorization keys of member networks.  We also desire to have in place the ability to work emergencies and nets with redundant talkgroup servers (now online: NATS) to insure smooth day-to-day communications as well as during priority and emergency events. 

Simply being able to load the time slots in the ham DMR world quickly and simply is a great reason to reach out to all the groups.   Other reasons are to play with DMR and TRBO as well as learning more about the technology, but also, connections can be simply for special functions such as hamfests, conventions and other demonstration events.  The connections can be short or long term, scheduled or impromptu.  The beauty of the c-Bridge is that connections can easily be severed, made dormant until needed and then reconnected, manually or dynamically.  Any administrator or manager of an  ISPC network knows how that can be problematic when adding or trying to delete repeaters from an IPSC network. But also, this method requires no trips to the hilltops and no worry about the network security being compromised by a disgruntled repeater owner or system operator.  This helps to insure that our approach remains politically neutral across all the independent Amateur DMR groups.

Important Caution:  Do not buy any equipment, especially DMR repeaters, before you know it will do what you want done.  Read this simple GUIDE or ask around first.  Motorola repeaters are the standard in Ham networking and no other manufacturers are able to network to Motorola's MotoTRBO repeaters.

DCI also participates in DMR nets and most managers turn on these talkgroups at the appropriate times so that users are able to participate.  4 DMR nets are automatically scheduled:  Worldwide, Tech Net, TAC 310 Net and the new QnA Hour.

DCI has c-Bridge connections to many other c-Bridges.  DCI actively supports the c-Bridge and the philosophy of connecting IPSC networks for many reasons and more especially the NATS concept of talkgroup servers.  Most importantly, peer slots on a simple IPSC network were finite and operationally, more problematic as the number of repeaters grow on a single IPSC network.  The c-Bridge broke that limitation wide open and now offers so much more than a simple party line on 2 time slots.  Talkgroups can be used for routing and this enables the use of more than a single Talkgroup on a Timeslot.  While not the complete answer to TRBO's IPSC limitations, it is a quantum improvement.

If you already have a TRBO repeater or you are part of an IPSC network, you are welcome to explore  bringing your repeater or IPSC network onto the  DCI Open IPSC network.  DCI can also peer in (join) to your network of 1 or more repeaters.  Whether to simply get your feet wet as you get up to speed and then move off into some other direction or you may desire a long term affiliation, our network managers are available to use and gain experience with TRBO networking.

If you have a c-Bridge, then it can easily link to our c-Bridges (or better: use NATS) and these types of links (conference connections) are preferred over that of putting a c-Bridge peer on your network or your repeater on our networks.  If interested in exploring these options, please Email us at: DCI Linking.  We also have a c-Bridge Forum if you wish to follow along in a more interactive setting.

DCI is also in favor of a nationwide DMR Emergency talkgroup.  More information on our All Call page.
