An issue that many have, is understanding clandestine and effective communication in a non-permissive environment. In this video, the Survivalist uses a DMR radio along with an attached “Jungle Antenna”, to send a message to his Family at their Retreat to let them know of his “Incoming” status, and also to check the security status of the Retreat.
NC Scout has written many posts on clandestine commo with different types of radios. I suggest you go back and read his posts, or better yet, get in on one of his classes. I’ve been trained in the military on many commo tasks, and I still got a lot out of the class I attended.
