Hi, i found this little mod for the ACRE radio modifacation for Arma 3. And it's just a comparison for what i think would be a nice addition for the game.

what i suggest is the ability to adjust your direct comms range.
like:
whisper = can be heared up 3-4m
talking = can be heared up to 15-20m
yelling = can be heared up to 50-60m

something like that. Of course the actual ranges can be varried, but i think it makes the ingame voice much more useable. often you don't want to talk to someone who seems to be no thread simple because the whole town will know you're there if you do. but if you could just whisper to someone in the next room you could maybe even make new friends without giving away your position to every person on the map. Hope you like my suggestion and consider it for the future development

edit: easiest way might be to re-enable 2 extra channels and redine them as whisper, talk and yell channel or something like that.
