Bruce gave you some good advice regarding the CornerPegging feature 
of SmartBeaconing.

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.
