What everyone's opinion on the Close Call feature? I have read Unidens take on it and how it works and what makes it work but as far as "field testing" goes, what is everyone's experiences with it. For example I get hits from across the small city I live in on my 996t and not in situations such as a fast food drive thru even when I am 10 feet away. I realize there is alot of variables such as output wattages etc.
