I got interested in Amateur radio on these forums. I tried CB which I used decades ago and there was nobody out there. I got my Tech lic in late 2014 and my Gen in mid 2015. Aside from providing excellent back country support via various high level repeaters, I also have HF access via a Yaesu FT-857 and ATAS antenna. I have spoken to people thousands of miles away sitting in my truck in the middle of nowhere. There are also digital HF modes which allow sending/receiving of emails and other modes of communication with the help of a computer. The hobby has been really great for me- meeting people, visiting and helping at repeater sites, soldering various kits together, learning a ton, and enjoying it immensely.
CB is limited to 4Watts and really only good for a close group but still viable as a communications system. Just not one I would rely on for emergencies. You can look up high level repeaters in the area you will be exploring and have them pre-programmed and ready. Repeaterbook has a great app I use often to find repeaters.
