“A DMR radio isn’t any good if it doesn’t have any frequencies or channels programmed into it. Programming your first DMR radio might feel a little bit daunting. It’s certainly different than programming an analog radio. So in part 2 in my series on DMR, we’re going to walk through the process of programming, or building a codeplug, for the Retevis RT82. But this content isn’t just limited to the Retevis, the process is similar for almost all of the Chinese DMR radios, so this information is also good for the other brands.”
