John Parnell has created a great series of Survival Communications books that are broken down by state/region. These books give you the info you’ll need to locate FCC licensed amateur operators in the event of a disaster that takes out cell phones, land lines and the internet. Access to BMRS/FRS radios, CB radios and ham or amateur radio communications could prove critical to your survival. Check out the full list of Survival Communications books and find one closest to your area.
