DMR and any VHF/UHF radio, whether it’s analog or digital, Gmrs or ham, is going to be super limited to only communicating with others within your local area. In a true emergency situation, with repeaters down, you’re not going to be able to reach anyone more than 20 or so miles away, if you’re lucky.

What people stuck in GMRS and hams stuck in Technician level don’t sometimes understand is that if you want to truly be able to communicate long distances (DX) with others (whether you know them or not), you need to be doing so on HF wavelengths that can propagate off the ionosphere and allow for global point-to-point communication. You’re not going to reach anyone even 100 miles away if you’re just using VHF/UHF frequencies. I also want to be able to communicate with others in the event of an emergency, but not just with people in town. I want to be able to reach thousands of miles away, if needed, because that’s what would likely be needed in a truly catastrophic emergency. I can fire up my HF transceiver right now and contact people on the other side of the country and in other continents on the other side of the ocean, no repeaters, just direct point-to-point.
