Bob it's been my experience that the dupe check only works for non moving
objects (lat/long does not change). The trackers that ping on every turn
get through the check and digipeat. We had one local gent teaching his
daughter driving lessons in a parking lot (with MANY curves and
obstacles) and you should have seen the packets going through a 1-1 then
bouncing off two local digi's! Both Wide digi's have dupe check enabled.
