I have dogs that bark too much to leave PTT off... I don't want to be broadcasting all my frustration, either... too many kids play that don't need to hear that kind of language.
Thank you for caring.
Really, there is nothing worse than someone with a mic on that has screaming kids, nagging girlfriends, crying babies, loud music and barking dogs in the background.
Now if more people would see the benefit of "push to talk" some people wouldn't have been banned for airing their frustration over an open mic.
