Everybody is on the right track on this jamming issue. Here's something that's unexpected. Use the same Military frequencies that they are not jamming. Maybe use modes that they don't use. If they try to do triangulation locating, they'll find themselves and possibly you. But.... You'll be long gone after making your super brief transmissions. Operating crossband is another way to drive them nuts. Transmit on 160 meters and receive on 80 meters. They'll be sitting on 160 meters waiting for a reply and get nothing. There are a ton of ways to skin that cat.
or dont use comms?
I dont have any and wouldnt know how to use them if I found them. From my point of view they would use satellites, drones, IR, etc... to locate people, smoke, tracks/trails, pets, heat signatures, etc...
They know who owns what properties, family ties, old family ties, ex family ties, neighbors, etc... and they can track anyone when we have no way of doing anything. Its just a matter of time before they come knocking on your door.
So with comms they may not be able to block you or listen in but they most likely can say there is an electronic signal coming from this area, send in the dogs....
Dont get me wrong, I wish I had the equipment and knowledge to use it but I dont so I make the best of what I do have
