5200 feet on a standard is just crazy out of the box... Was that after firmware upgrade too?? I can't believe the deviation on the standards, some people get 5k and other 500... Order of magnitude difference!!
It is probably the firmware, I just put same kid in standard and it didn't help at all... I am getting 900 ft in open area (beach south shore of LI) and 300-500ft in residential area (houses and trees etc.)
