There are currently five coordinated repeaters on the 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 an ID assigned by the DMR-MARC group. Getting an ID is easy and free! You may apply for an ID at the DMR-MARC website by using the “Register ID” link. It is preferred that all stations use an DMR-MARC assigned ID on all repeater slots on the system.

Additionally, Brandmeister has indicated that any new USA ID’s assigned that begin with the number “1” will not be able to use their network after May 1, 2018. Please beware you will need an ID that starts with the number 3 per the adopted MCC standard.

Private Voice Calls on NoCO DMR Network

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.

ID’ing Your Talkgroup

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.

Motorola Radio Users

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.
