Bruce gave you some good advice regarding the CornerPegging feature
According to the TT3 manual, you can configure both the Minimum Turn
Angle and the Minimum Turn Time. The angle is the minimum change in
direction required to trigger a beacon. As Bruce states, you don't
want that to be too small, probably no less than 15 degrees.
The time is the minimum time between beacons generated by the change
in direction. Let's say you are driving around in circles (looking
for a parking spot at Dayton, no doubt <g>). If your Minimum Turn
Angle is set to 15 degrees, you will send out 24 beacons by the time
you make a complete circle. But the CornerPegging routine also looks
at the Minimum Turn Time to decide whether or not it's too soon to
send out another beacon. If you set that parameter to, let's say 30
seconds and it takes you 2 minutes to complete the circle, you will
only send something like 4 beacons rather than 24.
