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
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
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
Simply being able to load the

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.
Caution: Do not buy any equipment,
especially DMR repeaters, before
you know it will do what you want done. Read this
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,
TAC 310 Net and the
new QnA Hour.
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
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
more than a single Talkgroup on a Timeslot. While not
the complete answer to TRBO's IPSC limitations, it is a quantum
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
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
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.
