What is DMR (Digital Mobile Radio) | DMR Radio | amateur radio | Aishi, vu3oos

Digital mobile radio (#DMR) is a digital radio standard for voice and data transmission in non-public radio networks. It was created by the European #Telecommunications Standards Institute (ETSI), and is designed to be low-cost and easy to use. 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 and TETRA uses a four-slot TDMA in a 25 kHz channel. #oscarconvention Register Yourself for OSCAR Convention : https://www.beaham.in Index DMR 0:00 Intro of OSCAR Convention 0:06 Introduction 1:01 DMR Projection 1:16 What is DMR? 1:46 Are there any special modes of operation of DMR? 2:07 What is trunking 2:27 Is DMR UHF or VHF? 3:08 What is DMR Zone? 3:26 What are the features of DMR? 3:52 What is TDMA? 4:08 Conclusion VHF UHF Basics | When you will use UHF and VHF:    • VHF UHF Basics | When you will use UH...
