We teach new hams that nobody owns a frequency, and as such, they may use any frequency they wish as long as they follow the rules. This is generally correct, however, repeaters are special. Owners can set their own rules.
Recently, I have heard people in the amateur radio community – especially in emergency communications circles – discussing the idea of using channel names or designators instead of frequency.
Whenever my article about Baofeng radio non-compliance is shared, I usually see a number of comments on it, and it usually starts quite an argument! I would like to try to clarify some of the misunderstandings people have. Update, September 28, 2018: I have added a few additional questions and answers.
There is a lot of confusion on whether DMR is legal to use in the amateur bands. The short answer is an unequivocal yes. DMR is legal on the ham bands.
