Using EMP-Hardened HF Ham Radio to Send/Receive E-Mail During ..

• survivalblog.com

 EMP may destroy routers, cell towers, and power sources; solar coronal mass ejection (CME) may remove power from all communications systems; cyber warfare may have similar outcomes. Travel in some of these circumstances will be difficult, or dangerous to impossible.

Ham radio VHF/UHF repeaters may go down, due to power outages or EMP. Direct, point to point simplex VHF Ham radio will still work (even after an EMP, if hand-held radios were at all hardened or protected) over modest distances. Long range HF direct Ham radio communications will work (possibly after a delay of any EMP), presuming you had protection (if EMP) and have your own power. However, they will be of less usefulness if you haven't established communications plans, frequencies, modes, and protocols with your loved ones. Without prior pre-arranged schedules, connecting directly with your intended recipient may take precious hours of transmissions, create immense interference to others, use precious power, and provide a very easy radio signature from your location.
