Introducing The W5AUM DMR Repeater

On August 5th, 2022, members from the Washington County Amateur Radio Club deployed a DMR repeater in Brenham. The equipment deployed includes a Motorola SLR5700 repeater, Cellwave UHF duplexers, and an AT&T LTE hotspot.

Digital Mobile Radio – or DMR for short – is an open standard/protocol for digital mobile radios defined by the European Telecommunications Standards Institute (ETSI), and is used in commercial products around the world. DMR was designed to allow for more bandwidth on a single frequency.

DMR is a TDMA (Time Division Multiple Access) mode, which means that several users can share the same frequency channel by dividing a signal into different time slots. Each frequency can support two time slots (slot 1 and slot 2) allowing simultaneous use from different operators at the same time.
