Personally I love DMR. I had a tough time programming my hotspot because when it comes to computer programming, I am as dumb as they come, but I figured it out. Programming the code (I wrote my own) was very simple. I love the idea of it but............... yes there is a but.
1. I don't like Digital in any form when it comes to getting a distance from the transmitter, tower, etc. When it comes to digital, either its all there or it isn't. In places where you can at least, with a good ear, make out a voice through the static om analog, with digital, that's not there. Too many times I have been on the fringe of a repeater or station and had a tough time. After switching to analog, I could at least make out through the static what was being said.
2. When it comes to talk groups, they are not all the same. Not only do you have talk groups to contend with, you have networks. You can have 5 different networks with all the same talk groups, BUT, none of the talk groups can talk to each other because they are all on different networks and the networks are not linked together. Of course, leave it up to the Hams who have the choice as to what they have on their repeaters and you could have an NEDECN repeater here but not another for 50+ miles but in between you will have a Brandmeister repeater. Your friend could be on a DMARC repeater and the only one available to you is Brandmeister. I live in a state where NEDECN rules the airwaves with only a few other repeaters on another network (which are out of range of me). I have Ham Friends in other states where they have a totally different network or their repeaters carry all 6 New England state talk groups where mine only carries 2 New England state talk groups. If I want to talk to other Hams on digital networks in my state, DMR is unpopular but Yaesu Fusion is spreading and is very popular (so I have been told). That means here is another digital radio I have to purchase if I want to talk around here. By the time you are done, you will have more radios than a 911 RCC in a large city, and thats just on 2 meters.
Overall, I enjoy DMR. I think that maybe some with rotten opinions of it should keep their mouths quiet when around newer Hams or Hams who are exploring different digital voice modes. I have heard nothing good about DMR from a lot of Hams because its allegedly a commercial digital mode not meant for Ham Radio, it wasnt created by Hams therefore "Its not real Ham Radio". To me, its another tool in the Ham Radio bag. Use it wisely, use it where needed, don't bad mouth it, but don't glorify it. It is what it is. It might not be for everyone, but it is good for some. Let others be and let them explore and settle into their own niche, not the majority.
