5. Ham radio: Old technology gets new respect


emergencyFox TV News reports that emergency managers seeking reliable backup communication in a crisis are finding new solutions in an old technology: ham radio

“It’s just another avenue, another opportunity for us to be able to communicate,” said Herb Schraufnagel KK4LRJ, public safety captain with Emory University Hospital Midtown, Atlanta.

Emory HealthCare is among a growing number of hospital systems to adopt ham radio. Hospital administrators and government officials took a lesson from Hurricane Katrina, which left some Gulf Coast medical centers isolated from the outside world, as landlines and cell towers failed.
