LTE networks often disappear before power does in real scenarios: long blackouts, traffic overload, or damaged infrastructure. We recommend that any outing with more than two people includes at least one programmed and tested VHF/UHF radio.
Start with an agreed primary channel and a backup. Do not rely on data-dependent apps. In open terrain, schedule check-ins every 30 minutes; in dense forest, shorten spacing between nodes or move to high ground to relay.
Use a common phonetic alphabet (Alpha, Bravo, Charlie…) and short phrases: position, status, need. Avoid long chats that clog the channel. If your team operates in multiple languages, agree on emergency keywords in one language only.
This protocol does not replace licensed training where the law requires it; it is a good-practice framework for practice groups and Modo Survival community outings.
