Radio Resources
Repeater directories and frequency references for staying connected in the backcountry
Radio is one of the most reliable communication tools in the backcountry, especially where cell coverage does not exist. Whether you are running a HAM handheld on 2m/70cm or a GMRS radio for group coordination, knowing what repeaters are in range before you leave is part of trip planning. These resources help you look up repeater coverage, frequencies, and licensing requirements.
