Imagine you are in occupied territory. You have built your underground, auxiliary, and G force. You are needing to get a one way message to all your local forces. You have already set up an listing SOI for them. You go out to a remote location away from prying eyes. You setup your antenna for 631 KHZ or 631 on ANY AM radio. You tune your XIEGU X6100 (that has been opened up so it will broadcast on that frequency and AM mode) to 631 KHZ, set the radio to AM. When the exact time that was stated in the SOI hits you send your 1 minute encrypted or encoded message to your local forces. You pack up and move one. Message sent. That specific mission accomplished.
