Ill have to get back to you with the frequency...but I use it every time I'm in the car...its good practice for the racing where one really needs it to compete. I think its a good test of where one is at driving wise as well as if you can hold a full conversation WHILE driving and keeping your cool/doing everything right, you know your doing well!
