The first question is usually, why do I want or need DMR? This turns out to be an easy answer in the commercial world, however a it can be a bit of a challenge in the amateur realm. The answers are pretty similar for both. DMR is a standards based RF modulation protocol making it easy for manufacturers to build equipment for. What this means to you is choice. Equipment can vary from $50 - $7000 or more. The standard puts most of the radios on a very even field though. Each radio must meet the standard to meet the DMR standard. In this section I'll explain why DMR is a great mode for both amateur and commercial radio operations.
