The Hoosier DMR repeater network was created in 2014 with the objective of building an all digital linked statewide DMR network. We are not a governing body in any way, we are a consortium, an alliance of repeater trustees with the same vision and values. Our trustee's are Motorola Service Station employees, commercial 2-way radio dealers, repeater enthusiasts, system installers, and Motorola equipment aficionados. Simplicity is our motto. The first DMR repeater in Indiana, the W9AMT Indianapolis machine, was established in Indianapolis in 2011 with the intent of bringing this widely popular and rapidly growing technology to the local amateur radio community. Just a few short years after its inception Hoosier DMR has grown into a statewide phenomenon, providing thosands of square miles of coverage throughout the state. 

Hoosier DMR welcomes all interested licensed amateur operators to experience the power of the DMR technology and utilize our open system. To learn more about becoming a DMR user, please visit our "Getting Started" page.

DMR, or Digital Mobile Radio, is an open source standard for TDMA digital communications. Originally designed for the commercial market by ETSI (the European Telecommunications Standard Institute), the DMR standard was adopted by the amateur community in 2008 with the intent of building a worldwide IP linked repeater network. Since then, the network has grown to over 3,500 repeaters. with over 51,000 users worldwide in nearly 70 countries. 


Firstly, DMR is an ‘open’ standard and is not proprietary to a single manufacturer. This means that competition is possible between manufacturers, which means lower prices on equipment compared to other digital voice modes like DSTAR and Yaesu System Fusion. The bigest advantage that DMR offers is that it employs TDMA (Time Division Multiple Access) technology, allowing for 2 time-slotted voice channels from one repeater and simultaneous data streaming for location based tracking, telemetry and text messaging capabilities. This means each repeater supports 2 unique voice channels at the same time! Basically, 2 channels in one! 


We are constantly building out our network and looking for new sites throughout the state to expand DMR coverage and bring this exciting new technology to as many amateur operators as possible. If you are a repeater trustee, with a coordinated (or non-interfering) frequency pair, on a UHF (70 CM) or VHF (2 M) frequency, with an established tower/antenna site and are interested in upgrading your equipment to the 21st century, please contact us. 

***Please note***

A DMR repeater requires a minimum internet connection of 750 Kbps or higher (recommended 1 Mbps) to be connected to our network. This can easily be achieved through a microwave link, DSL, cable broadband, T1 or a 4G LTE broadband router.
