Northern Colorado DMR

The Northern Colorado (NoCO) DMR group is a group of Northern Colorado amateur radio operators who operate and maintain an amateur radio DMR  repeater network. Usage of the repeater system is open to use by all licensed amateur radio operators with the appropriate privileges.

Information on how to program DMR radios and general system usage information may be found under Documentation.

We are open to hosting other repeaters on our C-Bridge. If you have a Mototrbo repeater that is or may be connected to the internet, contact us. There is no requirement to be local to the region.

About the Northern Colorado DMR Network

There are currently five coordinated repeaters on the Northern Colorado (NoCO) Network, three connected together with a Rayfield Communications C-Bridge, and two repeaters connected to the Brandmeister network. Both networks allow the slots on the various repeaters to be linked together either statically and/or dynamically. Typically, slot 1 on all the repeaters is known as the wide slot, where remote regional/national/worldwide links exist, while slot 2 is for local and regional links.

In addition to the C-Bridge network, our group also has repeaters connected with the Brandmeister DMR network. We have several Hytera repeaters on this network as well as one Motorola repeater. There are several talkgroups that are cross connected between the C-Bridge and Brandmeister networks.  Please see the talkgroups page for specific talkgroup information.

To link to other repeaters and devices on both the C-Bridge and Brandmeister networks, you MUST use a CCS7-ID. Getting an ID is easy and free! You may apply for an ID at the site. It is preferred that all stations use this CCS7-ID on all repeater slots on the system.

Private voice calls are OK on the repeaters on the system. Please do keep these private calls brief, as it locks out the ability of others to use the repeater slot while the private calls are in progress. Please yield usage of a repeater slot to group calls.

It is generally recommended when putting your call out on a group to also identify which group you are calling on. Many people scan with their radios and so if they just hear a call they may not know what channel to use to return your call.

It is also recommended that users of Motorola radios configure TX interrupt in their TX channel configurations. The C-Bridge uses TX interrupt for call arbitration, and although you might get bumped off the repeater, at least you will not be doubling with another station.
