K4USD Network

Supporting Amateur DMR Repeater Operators
(Revised 04/12/2016)

Amateur Radio Guide to Digital Mobile Radio (DMR): http://www.k4usd.org/guide.pdf

The K4USD Network operates a c-Bridge cloud (currently 65 managers) and a development cBridge offering connectivity to the core DMR-MARC, NATS, DCI and Brandmeister networks along with connectivity to other content (TG) providers.

Each DMR Repeater is typically assigned a c-Bridge Manager, your repeater can be configured as either a MASTER or PEER; most select configuring their repeater as a PEER so they do not need a static IP address.

We offer a standard configuration as listed below, but can customize within some limitations for your individual repeater needs. If there is a talk group you want that we do not have, we will try and obtain it for you. Please contact your local repeater operator for the layout of talk groups on specific repeater.

We do not charge for connectivity, but accept donations to cover the expense of licenses required for each repeater and hardware. Our data center is donated by one of our operators and is located near Dayton, Ohio.
