Southeastern Emergency Digital Association Network

While most Amateur Radio operators use VOICE to communicate, a growing number have connected their computers to their VHF ham radios to exchange information using a wireless network of digital repeaters and storage systems. One such system is the Southeastern Emergency Digital Association Network (SEDAN). Using nearly 50 digital repeaters installed throughout Florida, data can be transferred quickly and efficiently. SEDAN is managed by Barry Isbelle. The network has access to the State Emergency Operations Center in Tallahassee and the National Hurricane Center in Miami. Many city and county emergency operation centers also have SEDAN equipment. The draft Nassau County ARES communications plan lists SEDAN as the back-up digital communications scheme, behind Winlink. SEDAN is unique in that unlike either Winlink or D-Star, it's performance envelope is not dependent on having an internet connection.

For more info on SEDAN, contact Barry Isbelle via N2Db@bisbelle.com or check the SEDAN website. 

SEDAN operates only on 145.770 MHz. A map of the SEDAN nodes is on the SEDAN website here.
