The Metropolitan Amateur Repeater System (M.A.R.S.) including the Branson Repeaters is accessible via DMR Brandmeister TalkGroup: 31686.
DMR stands for Digital Mobile Radio. DMR is an open digital mobile radio standard defined in the European Telecommunications Standards Institute (ETSI) Standard TS 102 361 parts 1–4[1] and used in commercial products around the world. DMR, along with P25 phase II and NXDN are the main competitor technologies in achieving 6.25 kHz equivalent bandwidth using the proprietary AMBE+2 vocoder. DMR and P25 II both use two-slot TDMA in a 12.5 kHz channel, while NXDN uses discrete 6.25 kHz channels using frequency division. The standard has become popular within the amateur radio community due to the relative lower cost and complexity compared to other commercial digital modes.1
