Congratulations again Johny! Regarding your posting of interconnected repeaters, I wouldn't count on them being interconnected if TSHTF. The interconnection adds another level of complexity. which is reliant upon the internet, or microwave links. The simplest method of communication, simplex or point to point, is usually the most reliable, though perhaps not the most effective. The nice thing about amateur radio is that it teaches you how to use radio frequencies appropriate for the distance involved. Anyways, a Baofeng radio with a modest antenna is good for short distances, but I wouldn't count on it for large area coverage.
I'm looking forward to talking to other amateurs interested in getting a regional "prepper" net active. It'll be important to find a frequency that isn't already saturated with activity, probably on the high end of 75 meters.
