In the arena of grid down communications, wilderness plays a big part. In a SHTF scenario you will most likely find yourself operating outdoors at some point. With this in mind, your training should focus on operating in a less than perfect environment.
If you go outside and look around, you are sure to find somewhere you can practice your craft. It can be a park or maybe your friend’s woods? It may even be your backyard. Wherever you choose, get out of the house! Leave the comfort of your shack and go test your kit. You will not know what works for you until you find out what does not work for you! You need to work out the bugs now, not when the sky is falling. You can go camping and take your comms kit. Get your kids involved, set up a base station and give them frs radios to go “on patrol”.
