Has anyone figured out how to set the volume offset for all talkgroups in a FL at once? I find it better (for me) to have the volume offset set at +3 for most of my systems as I have a jeep and its so much easier to hear when the windows are open or top is down. So I'm trying to find a way to set all of the channels to +3 instead of having to go one by one. Thanks in advance.
