DCI MotoTRBO Ham Radio Linking Group
not affiliated with Motorola but we sure like their stuff

We are always looking for Net Control Stations for the weekly Tech nets.  If you would like to call the net, we welcome your interest.  Please Email Tech Net for more information or to set up for a net or a schedule.  Thank you!!!


DCI began as its life as a typo in March 2011 with the release of the c-Bridge.  We were a part of TRBO-6 since 2009 but we wanted to pursue wider DMR linking opportunities.  DCI's focus is to learn more about IPSC, c-Bridge implementation and 3rd party networking options.  We desire to converse with the wider DMR Ham community and offer a wide range of talkgroups to enable dynamic and efficient communications.

The main goals of DCI are to assist in the growth of DMR generally and MotoTRBO 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.  Network growth is very simple with the c-Bridge as it is so very easy to do and undo, without the need for the network keys of member networks.  We also want to have in place the ability to work emergencies and nets.  Just being able to load the time slots which tend to rather quiet in the ham TRBO world quickly and simply is a great reason to reach out.   Other reasons are to play with TRBO and learn, 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 or made dormant until needed.  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.

DCI has c-Bridge connections to: SF TRBO, NorCal, DMR-MARC, Georgia-DMR, AZ-TRBONET and more.  DCI actively supports the c-Bridge and the philosophy of connecting IPSC networks for many reasons.  Most importantly, peer slots on a simple IPSC network are finite and operationally, more problematic as the number of repeaters grow on a single IPSC network.  The c-Bridge breaks that limitation wide open and 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 have a single repeater or you are part of an IPSC network, are welcome to explore an affiliated repeater or IPSC network on DCI.  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 desire a long term linking plan, 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-Bridge (or better into a CPM on Q-B) 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 or use of CPM's, please Email us at: DCI Linking.  We also have a c-Bridge Forum if you wish to follow along in a more interactive setting.
