Be prepared for alternative communications. The 3-3-3 plan is a simple, universal protocol designed to let you reach family and friends when conventional networks fail.
Channel 3
Tune your radio to channel 3 on CB or PMR446. Radio amateurs use HF (7.133 MHz) and VHF (145.300 MHz).
3 Hours
Turn on your radio every 3 hours (00:00, 03:00, 06:00, 09:00, 12:00, 15:00, 18:00, 21:00).
