Post-Helene Update and the Importance of Radio After a Natural Disaster
It’s often said that modern communications infrastructure fails us after a disaster.

Why Radio Beats Everything in a Crisis​

• No Infrastructure Needed: Unlike phones, radios run on batteries and antennas.
• Range Varies: FRS for family chats (1-2 miles), GMRS for groups (5-20 miles), HAM for cross-state.
• Legal Note: FRS/PMR446 = no license. GMRS/HAM = license required (but emergencies suspend rules for life-saving use).
