I have to second the recommendation regarding amateur radio. You don't need to learn morse code, the Technician exam is really pretty easy with a bit of study, and once you have your license, you have access to a HUGE range of options for communications. Most Ham gear is designed for rough use. There's repeaters for your use with handheld radios smaller than an Altoids tin; you can also access Forest Service and Park Service frequencies with that same little HT when in the backcountry for bulletins and communication in an emergency.
