Radio Basics Presentation, by Saratoga

My purpose in writing this article is to focus attention on an area that is lacking for too many people. Having been in a group that did a lot of training, it became clear that this was an area that needed attention. We used email and cell phones to coordinate training location and times, but the thought was always in the back of my mind; what if there was no Internet or cell phones? How would we form up as a group? I have compiled the information into a simple, bullet-point scenario to make it easier to grasp and to focus on key areas. Also, there are exceptions to specific parts of this information, but for the majority of people it will apply.
