If you are totally bewildered and confused by ham radio and what options you have, start with my Basic SHTF Radio. This is a guide to let you know what your options are (if ham is too much for you, GMRS & FRS are great, easy options with a lot of close similarity to UHF ham that will work right out of the box).
I consider this next one to be the companion and "Intermediate SHTF Radio" to my basic book. Brushbeater, aka NC Scout, who runs an excellent radio course by all reports, has published his guide to using a Baofeng radio: The Guerrilla's Guide To The Baofeng Radio. If you have a Baofeng and kinda understand the basic of radio and what your needs are, or if you have a new Tech ham (amateur operator) license and need to figure the stupid thing out, start here. Also check out Scout's classes at Brushbeater.org.
