Let's say you have six people; one with some awareness, and five others who can fog a glass and get handed a radio and told 'press here and speak.'That is easy enuff to understand. In the case of the OP and his needs it seems like one licensed individual could instruct the others what and how to do it. Other than the obvious legal ramifications is there something else that would make this a no go in terms of jamming up the airways and has been stated?
Just trying to learn here, not trying to be difficult.
The six disperse to different physical areas. As they disperse, two find they can only communicate with one each of the other five, and, one of them keeps asking if anyone else can hear them. Yet another find that their radio's antenna has somehow fallen off but they try to talk anyway.
The one that keeps asking if anyone can hear is actually jamming the transmissions of two others but has no idea, and the one with the antenna that fell off burns out the transmitter because that is what happens when you do that.
The one 'licensed' person cannot be running around to the other locations to see why the communications 'system' has no chance of working as planned.
So, tell me again how this is a good idea?
Answer: get FRS radios. They do not have removable antennas, and they are always low power so they can't get far enough apart so only some can hear while others cannot. And nobody is breaking any laws.
