I've got this old old Whistler 425 radar detector, but I don't have the book on it. I can't even remember how long ago I bought it. Does anybody know what bands this thing picked up? Just X and K? Maybe KA? I plugged it in and it still appears to work. Don't get me wrong. I also have an X50 that saved me numerous times yesterday from Florida to Missouri (most in Alabama), but I'm wondering if I should just toss this thing or if it still has any redeeming value.
