It's a ham radio thing

Somebody needs to tell Google?
I have a few DMR. Designated Marksman Rifles. Most were built by: John Noveske.
Digital Mobile Radio. I have one - an Anytone D868UV - but I use it in analog FM mode only.
DMR, Yaesu's System Fusion and Kenwood's D-Star operate similarly: you use your radio to talk to a hotspot in your home or a local repeater. From there, your voice signal is digitized and sent to other repeaters and hotspots via the internet, not via radio.
For me, ham radio is about not having to rely on any infrastructure to communicate. These digital modes don't scratch that itch for me, so I haven't bothered with them.
What I will say about the D868UV is the color display is really nice, and the memory capacity is such that I can organize every repeater in New York State by county and even get some in northern PA programmed in. There are several thousand memory channels...I forget how many exactly.

We have a DStar handitalkie, but havent used it in years
Some guys at work, one in particular work digital at times. They like it ok, but agree its not gonna work for EmComm use in a grid down scenario

Is it like the trucker’s CB or is it different & how?
Mine was built by Doug Dinnard. guy was an artist.
Its ham radio. But it allows you to go thru the internet and talk around the world on VHF and UHF
So wait, is this thread about radios or rifles?
Radifles.
OH, like in Fallout 4?
Hmm... so if some targets are not in range, you can holler at 'em on the radio and tell 'em to move closer?
I know nothing of this DMR, I'm still learning the basic talky, lol.
I have Baofeng radios and I can go through the internet with those simply by hitting a repeater that is tied in.
I mostly use DMR now. There's 10 repeaters linked in south/central GA if anyone is interested. Its called the "Vidalia Net".
I agree the DMR through IP isn't worth a hockey when the grid is down. That's were HF shines.

If you have a smart phone, have you tried out Echolink?
I have used it periodically to check in to nets if I'm not near a repeater. I also have used Droidstar, but it's been glitchy.
I’ve spent enough money without adding DMR to the radio list.

There can be some overlap between ham radio and survivalism.
But in my view, any type of ham activity that uses repeaters is outside that overlap zone - ie it is purely part of the ham hobby.
In a very severe crisis (where the ROL is gone and communications by all other means are down), use of ham radio to gather information/communicate would be mostly 99% about listening and as little as 1% about transmitting.
Being that radio is insecure, none of your communications should be "in the clear".
That transmitting would be minimized by using single prearranged words that convey information about situation, progress, location, observations and intent (in much the same way the military does).
Even then, great care would need to be taken to ensure RDF can not be applied to your radio transmissions.

Is that triangulate.....? I did a search for RDF and it now refers to some computer stuff. My guess is Radio Direction Finder.

Correct.
I would not be alive without Triangulation. It is amazingly accurate.

Yep - works both ways.....same as most things can.
A bullet can save your life.....or it can end it.
Hey, you ham experts out there! What about ham radios aboard overland rigs? You know, 4WD vehicles equipped to cross trackless wastes AND outfitted with ham radios? Wouldn't they be harder to locate once the ham radio 'sender' finished his transmission and took off? That OAUSA.NET site was all about ham radios and overland rigs... I believe the guy who set up that site went on to create the American Adventurist Site, which is also pretty cool. 
For really bad times, I'm going HF with an NVIS antenna for local comms and a dipole up high to reach out far. I've been testing this with good results so far.
Line of sight transmissions invite trouble, so VHF and UHF are not really in my plan unless they're on extremely low power for very local communication.
Sure, you can set up rigs in vehicles. VHF and UHF are line-of-sight - if you can see the mountain top 12 miles away, you can talk to someone there. If you're in a valley and want to talk to someone on the other side of the mountain, you're out of luck.Hey, you ham experts out there! What about ham radios aboard overland rigs?

HF uses a very different antenna and bounces the signal off the ionosphere. There are HF antennas for vehicles, but how effective they would be for local communications is another matter. HF is designed to reach far, not within 100 miles.
But to address your point, yes, having your radios mobile will be helpful in avoiding being involved in a fox hunt.
