One of the comments I frequently received when the Signals Handbook, Volume One was released, was that it was to “tactical” and military oriented. Indeed, it was, because that is the intended audience. After browsing through many radio and communication threads on various discussion forums, it seems that some folks can’t separate the different ways a radio can be used. Radios are a valuable tool for “preppers” and other preparedness minded people. They can be used to monitor the local, and national situation. They can be used to call for help. They can be used to notify friends, family, and loved ones of someones status and well being. In short, they are a great prep tool. But that is not all they can do. Radios, and other signal methods can also be used for the protection and security of ones group. It is this niche application that the signals handbooks are being developed. Depending on the situation, any small group may face threats from the outside world. It is this rare, but dangerous condition that the small team can be greatly aided by good COMSEC procedures, proper radio discipline, and a little bit of practice.
